General data
■ Area of application
The SENTRIC LD switches are used for switching main and auxiliary circuits, but also for switching induction motors and other
loads during maintenance and repair work.
They are manually operated switch disconnectors according to
IEC 60947-3/VDE 0660 Part 107 (EN 60947-3) and fulfill the conditions for switch disconnectors.
The SENTRIC LD switches can be used as
• On-Off switches
• EMERGENCY-STOP switches
• Main control switches to EN 60204-1
In EN 60204-1 (VDE 0113 Part 1), main control switches are
called "mains isolating devices", while EMERGENCY-STOP
switches are termed "devices for emergency shutdowns". Maintenance personnel can protect themselves against unauthorized
startup with padlocks (up to three can be fitted).
■ Design
Switches for distribution board mounting
The switches for distribution board mounting are suited for use
in switchboards and for switching inside control cabinets or distributors. They have cap and fitting dimensions to DIN 43880
and can be fitted under the same cover together with miniature
circuit-breakers. The selector switches can be locked in their Off
position with up to 2 padlocks with a hasp thickness of 6 mm.
Switches in molded-plastic enclosure
For surface mounting of individual main control and EMERGENCY-STOP switches, molded plastic-enclosed switches to degree
of protection IP 65 are used. The operating elements can be
locked in their Off position with three padlocks with a hasp thickness of 8 mm.
The molded-plastic enclosures each contain an N and/or a
PE/ground terminal.
1) 16 A versions have four contact elements; 3-pole changeover switches
and 6-pole main control switches have six contact elements.

3LD2 530–0TK11 switch for distribution board mounting

Construction of the contacts
Each switch has three adjacent contact elements1). A fourth
leading switching element for switching the neutral conductor, a
continuous PE/ground terminal, an auxiliary switch (1 NO or 1
NC or 1 changeover contact) can be fitted to each side of the
switch. The auxiliary switches operate as leading contacts on
opening. On opening, the make contact opens before the main
contacts, so that a contactor carries the switching duty in the circuit and the service or safety switch switches at zero current. On
closing, the auxiliary switch switches later than or at the same
time as the main contacts.
Switch construction
Construction of rotary operating mechanisms
The rotary mechanisms of the switches for front or base mounting are mounted on control panel doors, front panels or side
walls with four-hole or center-hole mounting with a standard diameter of 22.5 mm and operated from the outside. In their Off
position, they can be locked with up to three padlocks with a
hasp thickness of 8 mm.
Switch position indication
The switch position is clearly marked with direction arrows and
an "O" for OFF and a "I" for ON at the front.
Switches for front mounting
The switches for front mounting are connected directly to the rotary operating mechanism through the fixing screws or – in the
case of center-hole mounting – a special-purpose coupling.
Switches for base mounting
The switches for base mounting are snapped onto 35 mm
mounting rails to EN 50022 or screw-mounted on mounting
plates.
The actuators are connected to the lower section of the switch
through a door coupling, which can be released in its zero position, and a 300 mm long switch shaft. When the control cabinet
door is open, the switch can be protected against inadvertent
operation by removing the switch shaft from the lower section of
the switch.

switch in molded-plastic
enclosure
The mounting depth can be adapted to individual requirements
by adjusting the switch shaft length.

SENTRIC K Switch Disconnectors from 63 A to 1000 A
General data
■ Design
SENTRIC KA and 3KE switch disconnectors are used as main
control, EMERGENCY-STOP, maintenance and transfer switches
in distribution boards for residential and non-residential buildings as well as industrial switchboards. As three and four-pole
variants, they ensure activation and deactivation of the specified
rated current under load. At the same time, they constitute a
safety isolating function and isolating distance in all low-voltage
circuits.
By virtue of their design, all 3K switch disconnectors feature
double contact interruption and an isolating distance. Therefore,
the fuses are de-energized when the switch disconnectors are in
the disconnected position.
All 3K switch disconnectors are climate-proof and meet the
requirements of IEC 60947-1, IEC 60947-3 and VDE 0660
Part 107.
A changeover operating mechanism is available for the use of 2
switch disconnectors in the 3KE series as load changeover
switches.
Switch disconnectors in the type-tested 8HP molded-plastic distribution board enclosure (degree of protection IP65) are available for use as safety switches.
An operating linkage permits simultaneous switching of two 3KE
switch disconnectors with identical or different rated operating
currents.
The system components can be selected in the "8HP System"
catalog (Order No. 8ZX1012-0HP54-5AB1) (in German only).
Identical accessories for 3KA, 3KL and 3KM switch disconnectors with and without fuses simplify keeping of stocks.
For the SENTRIC KA switch disconnectors, complete kits for
standard and EMERGENCY-STOP use are available for installation in the side and rear panels of switchgear cabinets.

■ Benefits
■ Functions
• Lockable with 3 padlocks
• Generous terminal chamber
• Degree of protection IP65
• Maintenance-free
• Easy mounting
The concept and mechanical construction of these switches are
designed for reliable function even under the harshest conditions. In emergencies, every second counts, and our switches
allow immediate isolation.
Our enclosed main control and EMERGENCY-STOP switches
can be locked with up to three padlocks and are available in two
ergonomically designed versions from 16 A to 1000 A.
Our main control and EMERGENCY-STOP switches provide absolute safety, even during maintenance and repair work. Allround safety for people and machines.
With their high degree of protection IP65, they can even withstand dust and water jets, providing unparalleled safety in the
building and industrial installations as well as the food and
chemical industry. Even with the enclosure open, they meet
Safety Class 2. IP20 is the minimum!

SENTRIC NP Fuse Switch Disconnectors
General data
■ Design
SENTRIC 3NP4 and 3NP5 fuse switch disconnectors are switching devices for the occasional manual switching/isolating of
loads and distribution boards. They are capable of switching on,
carrying and switching off the specified rated current (including
a certain overload).
With SENTRIC 3NP4 and 3NP5 fuse switch disconnectors,
downstream electrical loads are safely isolated from the supply,
disconnecting all poles and under load.
The SENTRIC 3NP4 and 3NP5 fuse switch disconnectors are
ideally suited to surface mounting and flush mounting in switchboards (e.g. ALPHA, SIKUS), meter cabinets (e.g. ALPHA 400ZS), and molded-plastic distribution systems such as SENTRIC
8HP.
The possibility of mounting on a wide variety of busbar systems
allows a broad scope of application in control cabinet manufacture and control engineering.
The SENTRIC 3NP4 NH 0002) and NH 00 sizes can be snapped
onto a 35 mm standard mounting rail and are ideal for use in
combination with other switching devices, for example in capacitor modules for reactive power compensation.
SENTRIC 3NP4 and 3NP5 fuse switch disconnectors
6
In conjunction with semiconductor protection fuses (e.g. SITOR),
these are used for the effective protection of frequency converters and soft starters.
SENTRIC NP fuse switch disconnectors
The SENTRIC 3NP4 and 3NP5 fuse switch disconnectors consist
of a fuse base and a removable fuse carrier with inspection window and measurement function window.
Lyre-shaped contacts, arc chutes and connection pieces are integrated in the base. The fuse carrier holds the fuse links or isolating links.
The links can be replaced without the use of tools.
The three conducting paths in the base and the fuse links in the
fuse carrier are separated by partitions, which overlap when the
unit is opened and closed.
This powerful intrinsic protection is known as "full compartmentalization", and efficiently and effectively prevents flashover between the phases.
The SENTRIC 3NP5 fuse switch disconnectors are additionally
equipped with locating springs at the side of the base. These allow "high-speed closing" of the device regardless of the actuating speed of the operator.
LV HRC fuses of sizes NH 000 to NH 3 according to IEC 602692-1 and DIN VDE 43620 are used in the SENTRIC 3NP4 and
3NP5 fuse switch disconnectors. SITOR semiconductor protection fuses can also be used.
Further information is provided in the operating instructions for
the SENTRIC 3NP4 and 3NP5 fuse switch disconnectors.
Auxiliary switches
The SENTRIC 3NP4 and 3NP5 fuse switch disconnectors can be
retrofitted with auxiliary switches for signaling the switching position of the fuse carrier.
One switching element (1 CO) can be fitted to size NH 000
SENTRIC 3NP4 fuse switch disconnectors, or two switching elements (1 CO) to sizes NH 00 to NH 3.
The SENTRIC 3NP5 fuse switch disconnectors can optionally be
supplied with a 2-pole auxiliary switch (1 NO + 1 NC). The variant with fuse monitoring is always equipped with this auxiliary
switch.
3NP40 10
3NP40 70
3NP52 with open fuse carrier
The SENTRIC 3NP4 and 3NP5 fuse switch disconnectors are
suitable for use in any climate and comply with standards
IEC 60947-1, IEC 60947-3 and DIN VDE 0660 Part 107.
The SENTRIC 3NP5 series and the 3NP40 1 and 3NP40 7 variants are available as tin-plated version for use in extremely sulfurous atmospheres (available on request).
In addition, the SENTRIC 3NP5 fuse switch disconnector series
complies with BS 5419 and also has marine approval.1)
All SENTRIC 3NP4 and 3NP5 fuse switch disconnectors can be
sealed, either as standard or using accessories.
1) Use only approved fuse links.
2) Corresponds to fuse sizes NH 000 (NH 00C) or NH 00 with
reduced dimensions; maximum width 21 mm to IEC 60269-2-1 and
DIN VDE 43620.

General data
■ Functions
Fuse monitoring with SIRIUS circuit-breakers
Electronic fuse monitoring (EFM)
To allow fuse monitoring a SIRIUS circuit-breaker is fitted in the
factory, permanently wired and mounted on the fuse carrier of
the SENTRIC 3NP4 and 3NP5 fuse switch disconnectors.
With electronic fuse monitoring, the fuse monitoring system is fitted in the factory, permanently wired and mounted on the fuse
carrier of the SENTRIC 3NP5 fuse switch disconnectors.
When the fuse carrier is closed, the three conducting paths of
the SIRIUS circuit-breaker are switchable in parallel with the fuse
links being monitored. When the fuse carrier is open, all main
conducting paths of the circuit-breaker are de-energized.
The monitoring system works whether or not a load is present.
The failure of a fuse can be signaled to a control room by a group
fault signal via integrated auxiliary switches (2 NO + 1 NC) or
used to isolate the load via a contactor, for example.
The internal resistance of the circuit-breaker is sufficiently high
so that it does not impair the protection function of the monitored
fuse links.
The actuation of the auxiliary switches depends on the version
of the monitoring system. Version "A" stands for "open-circuit
principle", and version "R" for "closed-circuit principle" (see block
diagram).
If a fuse blows, the circuit-breaker trips. The auxiliary switch of
the circuit-breaker can be used for signaling or to open the main
circuit, for example via a contactor.
For size NH 00 SENTRIC 3NP4 fuse switch disconnectors the
signal lead must be ordered separately. For sizes NH 1 to NH 3
the connection is via flat connectors.
The signal lead for SENTRIC 3NP5 fuse switch disconnectors is
enclosed with the unit as ordered, including connector.
Fuse monitoring by SIRIUS circuit-breakers is not permissible for
circuit-breaker controlled feeders subject to reverse feed of
more than DC 220 V in the event of a fault.
In the event of a fuse rupture, a flashing signal on the device indicates a general malfunction with a green LED and the position
of the failed fuse is indicated by a red LED. If more than one device is used, it is easier to identify the relevant feeder.
The EFM automatically returns to the standby position as soon
as the defective fuses have been replaced. Visually this status is
indicated by the status display (green LED).
The electronic fuse monitoring system is also suitable for use in
industrial networks that are especially subject to the effect of harmonics.
With parallel cables and meshed systems, a voltage difference
of more than 24 V is necessary at the switch in order to cause
tripping.

SENTRIC KL and 3KM Switch Disconnectors with Fuses
General data
SENTRIC KL and 3KM switch disconnectors with fuses protect
against overload and short-circuits as main control and EMERGENCY-STOP switches for switchboards, distribution boards,
power supply feeders and motor feeders. In conjunction with
Siemens SITOR semiconductor protection fuses, they are also
used in UPS systems, frequency converters and capacitor control systems.
All SENTRIC K switch disconnectors are climate-proof and meet
the requirements of IEC 60947-1, IEC 60947-3 and VDE 0660
Part 107.
■ Design
All switch disconnectors feature double contact interruption and
an isolating distance. As a result, the fuses are de-energized
when the switch disconnectors are in the disconnected position.
Generally, all SENTRIC 3K.5 switch disconnectors can be secured on the shaft with a padlock to prevent unauthorized reclosing.
The 3KM switch disconnector fuses also feature an isolating
plug connector. This facilitates installation and contact establishment in motor control centers (MCCs) in conjunction with vertical
busbars.
The fact that the accessories for SENTRIC KA, KL and 3KM
switch disconnectors with and without fuses are identical simplifies the keeping of stocks.
Please inquire about a special variant with reduced values that
is particularly resistant to atmospheres high in sulfur, e.g. in the
paper and cellulose processing industries.

SENTRIC NJ In-Line Fuse Switch Disconnectors
General data
■ Benefits
Parking position
All SENTRIC 3NJ in-line fuse switch disconnectors are fed via
the busbars. The outgoing current is transported via cable (see
"Terminal positions").
For maintenance purposes, for example, the carriers of the
single-pole in-line fuse switch disconnectors of sizes 1 to 3 and
the three-pole in-line fuse switch disconnectors of size 00 can be
mounted after being turned by 180° (fuse facing outwards).
With SENTRIC 3NJ41 in-line fuse disconnectors it is possible to
choose between having the cable connection on top or on bottom (standard version) by turning the contact carrier. The upper
part can be removed completely. This ensures easy installation.
This results in the following advantages:
• Visible disconnection point
• Depot for fuse links (parking position)
• No opportunity for mistakes on replacing the fuse links
• Additional touch protection in the vicinity of the lyre-shaped
contacts
Inspection holes
SENTRIC 3NJ41 and 3NJ56 single-pole and three-pole in-line
fuse switch disconnectors are designed for installation in lowvoltage distribution boards, substations and cable distribution
cubicles.
They are suitable for use in any climate.
In an open position, they are safe from touch by the back of the
hand (exception 3NJ56: IP00). When the fuse carriers are
closed, the degree of protection for all in-line fuse switch disconnectors is IP30. They comply with the following regulations:
IEC 60408, IEC 60947-3 and VDE 0660 Part 107. Fuse links in
compliance with DIN 43620 Part 1 can be used – nickel-plated
fuse blades are not permissible due to the high transfer resistance.
■ Design
Mounting position
The SENTRIC 3NJ in-line fuse switch disconnectors can be
mounted vertically or horizontally. When fitted horizontally, however, system-specific reduction factors and the coincidence factor (DIN VDE 0660 Part 500 4.7) according to the applicable
system regulations must be observed.

The 3NJ4 and 3NJ5 in-line devices are also available on request
for the following applications:
• In-line feed-in device for 1600 A: two parallel-connected size 3
in-line devices with isolating links fitted instead of the LV HRC
fuses (only 1-pole switching)
• In-line busbar isolating devices with side feeders for isolating
or connecting two busbar systems (sizes 1 to 3)
• Parallel-connected in-line devices for 800 A or 1250 A
(only 1-pole switching)
■ Integration
Assembly kits as well as TTA modules and partly equipped sideby-side cabinets are available for installation in the SIKUS 3200
(8GG) modular distribution board system; see Components for
distribution systems.
3NJ41 in-line fuse switch disconnectors
The SENTRIC 3NJ in-line fuse switch disconnectors for mounting
on 185 mm busbar systems are available in the following versions and sizes:
Installation in SIKUS Universal (8GF) is also possible. Please inquire.
Size 1 for 250 A, 1- or 3-pole switchable
Size 4a for 1250 A, 1-pole switchable
The size 00, 160 A three-pole in-line fuse disconnectors are
available for 100 mm busbar center-to-center distance and only
as a special version for 185 mm busbar center-to-center distance.
Instead of one size 1 to 3 disconnector, two size 00 disconnectors with an adapter and masking frame can be used (see
Accessories) on a 185 mm busbar system.
The swiveling mechanism with three-pole switchable disconnectors of sizes 1 to 3 is lockable and ensures simultaneous switching of all three phases.

Plug-In In-Line Switch Disconnectors with Fuses
Up to 630 A
■ Overview
3NJ6 plug-in in-line switch disconnectors with fuses are typetested to IEC EN 60947/3 and can be used for voltage levels up
to AC 690 V/DC 500 V. The compact design is optimized for
switchboards using plug-in technology. The units can be installed horizontally or vertically. All sizes are available in 2-, 3- or
4-pole versions. The front masking frame is automatically interlocked in the ON position. With the front masking frame closed,
the degree of protection is IP41. The 3NJ6 plug-in in-line switch
disconnectors have a short-circuit strength of up to 100 kA. All
device variants can be equipped with solid-state fuse monitoring
or a communication function.
■ Benefits
Advantages for users and operators
• Conversion, upgrading and replacement without deactivating
the switchboard
• Off-circuit fuse replacement
• Free of maintenance
• High level of personal safety
• Operating handle lockable in the OFF position
• Clear switch position indication
• Electronic fuse monitoring
• Data display via bus systems and Internet through COM function
• Modular accessories for retrofitting and expansion
• Low power losses and therefore economical operation of the
whole switchboard.
Advantages for makers of switchgear and controlgear
• Modular compact design in a 50 mm grid pattern
• Easy and economical assembly thanks to plug-in contact on
the incoming side
• High packing density in the cubicle
• Cable connection with cable clamps or cable lugs
• Can be mounted in various depths of control cabinets
• Comprehensive range of accessories
• Integrated COM function makes additional external equipment
unnecessary.
3NJ6 plug-in in-line switch disconnectors with fuses are ideal
wherever distribution boards have a minimum of space but need
to accommodate as many cable feeders as possible for power
distribution. They can be easily installed in all the industry-standard control cabinets (a depth of at least 400 mm) as well as in
the Siemens 8MF/8MC cubicles and in the SIKUS switchboards.
They are supplied as prefabricated disconnector panels in the
SIVACON switchgear assemblies.
The 3NJ6 plug-in in-line switch disconnectors are available for
rated continuous currents of 160 A to 630 A. LV HRC fuse links
to IEC 60269-1/EN 60269-1 (sizes 00 to 3) take care of overload
and short-circuit protection up to AC 690 V/DC 500 V.
Typical applications are to be found in industry, power stations,
building services, hospitals, hotels, airports and shipbuilding.
The 3NJ6 plug-in load isolating switches fulfill all functions safely
and reliably:
• Power distribution up to AC 690 V and DC 500 V at high shortcircuit strengths
• Feeder circuit-breaker and outgoing circuit-breaker in subdistribution boards
• Fuse protection of lightning and overvoltage protection devices
• Short-circuit and overload protection for frequency converters
and soft starters
• Internal cost center acquisition

SITOR Semiconductor Protection Fuses
■ Benefits
UL approval was achieved for the 3KL switch disconnectors with
fuses in conjunction with the new range of 3NE1 ...–2 fuses.
Due to the mechanical stress on the relatively long fuse blades,
3NE41 SITOR fuses should be switchable only occasionally and
only at zero current. If it is only permissible to switch at zero current, the switch must be marked accordingly.
The use of SITOR fuses rated above 63 A for overload protection
is also not permitted when gR fuses (except 3NE1) are used.
When SITOR fuses are used in 3NP, 3KL and 3KM switch disconnectors, a partial reduction of the rated current of the fuse is necessary due to the higher power loss in comparison with LV HRC
fuses for line protection. The use of SITOR fuses in switch disconnectors may at times result in current values above the rated
currents of the switches. These increased currents occur only
when the switch is used with SITOR fuses; they cannot be utilized when the switch is used with standard LV HRC fuses. Details are given in the table below.
When SITOR fuses of types 3NC24, 3NC84, 3NE33 and 3NE43
are used, the switching capacity of the switch disconnectors as
specified in the catalog must not be fully utilized, as the blades
of these fuses (in contrast to LV HRC line-protection fuses) are
slotted. Occasional switching of currents up to the rated currents
of the fuses is permissible.
The operating voltage is limited by the rated voltage of the
switch disconnector or the fuses. During current-free switching,
the limit value is the rated insulation voltage of the switch disconnector.
The 3NE1 “double protection fuses” can be used both as allrange fuses (gR/gS) as well as for semiconductor and lead protection.
Due to the dimensions of SITOR fuses, only the fuses shown in
the Selection and ordering data below can be used in the 3NP,
3KL and 3KM switch disconnectors.

3) in accordance with EN 60947-1 is maintained, the rated insulation voltage of the SENTRIC 3NP switch disconnectors also amounts to
Ui = 1000 V.
3) Due to the mechanical stress on the relatively long fuse blades, 3NE41
SITOR fuses should be switchable only occasionally and only at zero current.
