Advanced design vacuum circuit breakers
ADVAC
Universal applications:
− Medium voltage motor starting applications
− Capacitor switching
− Retrofit applications to replace existing circuit breakers in
repetitive duty applications
Available for 5, 8.25, and 15 kV
applications, in stationary and drawout
forms.
ADVAC circuit breakers have been fully tested to the most
recent versions of ANSI C37.04, C37.06,and C37.09. Using "k"
factor equals 1 as the test criteria.

ADVAC. The circuit breaker.
The new ADVAC circuit breaker continues to improve upon previous designs. Although some aspects remain unchanged, the
differences set this generation of circuit breakers apart from the
rest. The operating mechanism was refreshed with the EL mechanism featuring quick and easy accessory installations. New
programmable “smart” coils provide close, open, and undervoltage actuation of the breaker. All models feature embedded
poles that attain excellent dielectric and thermal capabilities as
well as provide superior protection against outside influences.

ADVAC
Summary of benefits:
− Manual provisions to charge, close, and open the breaker
− Built in charging lever
− EL mechanism features extremely limited and simple
maintenance
− Mechanical anti-pumping device supplies as standard
− Quick and easy smart coil installation
www.nepsi.com
A sturdy metal frame provides the support for the operating mechanism and the poles. This frame also allows for the breaker
to be mounted as a fixed version. The operating mechanism
harnesses stored energy and free trip allowing the opening
and closing operations to be independent of the operator. The
operating mechanism is a simple module containing the electric
motor and gears necessary to provide charging of the closing
spring. This construction allows for simple removal of the mechanism as a complete assembly and greatly increases the reliability of the apparatus. The mechanism can also be customized
with various accessories that are quick and easy to install. The
new smart coils integrate all necessary components required for
electrical operation of the breaker. The smart coils are simple to
install due to their modular design.

AMVAC. Qualities that convince.
The vacuum interrupter assembly consists of the interrupter and
the current carrying parts completely embedded in a proprietary
epoxy resin. Thermal performance of the interrupter is improved
as the epoxy resin draws heat away from the hot spots for a
more even heat distribution. Moreover, the interrupter pole assembly is fully skirted so that push rod and other moving parts
of the current transfer area are isolated and protected from
external influences. As a result, accumulations of dust, dirt, and
condensation do not increase tracking and partial discharge as
they do in non-embedded designs.

ADVAC. Smart coils.
Open, close, and undervoltage coils
allow remote operation of circuit breaker
functions.
www.nepsi.com
Smart coils provide electrical control of the mechanical functions of the circuit breaker. One open and one close coil are
installed as standard parts for basic circuit breaker operation.
An additional open coil can be easily installed and wired to a
circuit completely separate from the first open coil. An undervoltage release can also be easily installed to provide circuit
breaker opening if there is a notable drop in voltage. The coils
can both operate in direct and alternating current. Installation
of these coils only involves securing the coil with a couple of
screws and connecting a wire plug. The coils are programmed
at the factory and ready to install upon arrival.
ADVAC. Stored energy operating mechanism.
ADVAC uses a simple, front-accessible stored energy operating
mechanism designed specifically for use with vacuum technology. This provides the benefits of dependable vacuum interrupters with advanced contact design and proven reliability, without
the complexity of mechanisms and linkages found in previous
generation circuit breakers.
www.nepsi.com
The EL mechanism can be charged manually using the spring
charging lever or electrically by the spring charging gear motor.
While activating one of the above mentioned methods, the cams
(2) on the rotating operating shaft (1) move the closing lever
assembly (3) to charge the closing spring.
A part of the closing spring’s force works on the closing hook
through the closing lever assembly and the pin of the cam/toggle assembly (1). The closing hook remains locked by the closing
shaft (2) and the opening hook reaches its position where it
receives the central hook of the cam/toggle assembly (3). The
breaker signals that it is charged.
Activating the closing push button rotates the closing shaft and
releases the closing hook (1). The stored energy of the closing
spring is transferred to the closing lever assembly (2) which pushes the long levers of the cam/toggle assembly connected by
a pin (3). The long levers move the main shaft counter-clockwise (4) which transfers the motion to the push rods connected
to the contacts in the vacuum interrupters. The breaker signals
that it is closed
The charging motor (if present) automatically rotates the operating mechanism. The closing spring is now charged again and
ready for the next closing operation.
Activating the opening push button rotates the opening shaft
and releases the opening hook (1). This action releases the
central hook of the cam/toggle assembly (2) allowing the contact and opening springs to transfer their energy to the long
levers (3). The main shaft rotates clockwise (4) and the breaker
signals that it is open.
www.nepsi.com
The long levers reach their settled position (1) once the breaker
is closed and are held by the central hook of the cam/toggle
assembly (3). The contact springs inside the poles and the opening spring inside the frame are charged. The contact springs
maintain contact pressure while the breaker is in the closed
position. The central hook applies force to the opening hook (4)
which is locked by the opening shaft (5).

stored energy operating mechanism. The breaker is intended
for use as a General Purpose device in accordance with applicable ANSI standards applying to 5, 8.25, or 15 kV applications:
ANSI C37.04, C37.06, and C37.09. The circuit breaker shall
also conform to the general purpose capacitor switching ratings
referenced in the ANSI standards.
Drawout circuit breaker racking system and interlocks
The circuit breaker shall be inserted and withdrawn by means of
a racking system, which can be operated with the compartment
door open or closed. The racking system shall provide smooth
consistent racking, and shall secure the breaker from both sides
of the cell in all racking positions. During racking, the breaker
shall automatically open and close cell-mounted safety shutters
to cover stationary primary contacts when the breaker is not in
the “Connected” position.
The racking system shall have three distinct positions. In addition to the withdrawn position (free movement): “Disconnected”
(both primary and secondary contacts disengaged), “Test” (secondary contacts engaged, primary contacts disconnected, and
shutter closed), and “Connected” (shutter open, primary and
secondary contacts engaged). Positive stops shall be provided
for all three positions, with deliberate operator intervention required to enable continued insertion or withdrawal of the circuit
breaker from any position.
The racking system and all moving parts of the breaker-cell
interface, including the secondary disconnects, shutter actuator
and ground contact, shall be capable of 500 complete rack-in/
rack-out operations without maintenance.
It shall not be possible to insert or withdraw a closed breaker,
and the breaker shall not be allowed to close within a cell unless it is in the “Connected”, “Test”, or “Disconnected” position.
Electrical and mechanical blocking means shall be employed
to preclude breaker contact closure in any position other then
“Connected”, “Test”, or “Disconnected”. The springs in the
Controls
Opening and closing speed shall be independent of the operator or of control voltage within the rated control voltage range.
Circuit breaker charge, close and trip circuits shall be electrically
separate, and control voltages for each circuit shall be independently selectable from the full range of ANSI preferred control
voltages. Manual provisions shall be provided for closing,
tripping and charging the breaker. These provisions shall be
installed and easily accessible at the front of the breaker.
All control components shall be front accessible for quick
inspection after easy removal of the circuit breaker front cover.
Mechanism operated cell switches shall not be allowed; the circuit breaker shall include eight on-board auxiliary contacts (four
normally open “a” and four normally closed “b”) for customer
use, wired through the secondary disconnects. All breakermounted contacts shall operate in both the “Connected” and
“Test” positions.
Option:
Nine additional contacts (for a total of nine normally open “a”
and eight normally closed “b”) shall be installed on the circuit
breaker and wired through the secondary disconnect, for a total
of 17 on-board contacts.
The breaker shall have flags to indicate open or closed position, and spring charge status. Only the correct status flag for
any single function shall be visible. Pointer systems shall not be
used to indicate status. Additionally, the breaker shall have a
five-digit, non-resetting operation counter clearly visible from the
front of the breaker. The operation counter shall advance when
the breaker closes.
All control devices shall be universal AC/DC, for AC or DC application flexibility with standard parts. All control components
shall be front-accessible for inspections and easily removable
for maintenance.
Option:
Dual open coils shall be supplied for breakers as noted on data
sheets, and wired through separate secondary control sources
for complete redundancy.

Option:
Definite purpose capacitor switching ratings are optionally
offered for single and back-to-back applications. Details of
these applications are required at the time of quotation to insure
conformance to specific applications.
stored energy device operating mechanism shall be automatically discharged prior to removing a circuit breaker from a compartment (other than spring preload charges which do not have
the capacity to operate the circuit breaker).
Option:
A direct-acting undervoltage trip shall be supplied for breakers
as noted on data sheets. The undervoltage trip shall operate
when the control voltage drops to a predetermined value below
the nominal control voltage.
Current path
Each primary lead assembly shall consist of a vacuum interrupter completely embedded in an epoxy resin casting. The
epoxy casting shall encapsulate not only the vacuum interrupter,
but also the upper and lower current carrying parts and current
transfer assembly. The epoxy casting shall limit access to any
moving parts, protecting them from dirt and debris. Epoxy encapsulation shall be used on all 1200 and 2000 ampere circuit
breakers. The 3000 ampere circuit breakers shall use individual
ventilated pole assemblies that shield and protect the vacuum
interrupters. Connecting directly to the pole pads, silver-plated
copper upper and lower leads shall use tulip type self-aligning
primary disconnects. A dedicated ground contact shall be
provided to engage the stationary ground contact in the circuit
breaker compartment to ground the circuit breaker in all positions from “Disconnected” through “Connected”.

The EL actuator shall have a mechanical anti-pumping device
mounted to prevent a continuous succession of close-open operations. The anti-pumping device allows the breaker to close
if the operating mechanism spring is fully charged, the opening
push button and/or shunt opening release are not activated,
and the circuit breaker is open simultaneously.
Maintenance and handling
The operating mechanism shall be front accessible, and all
routine maintenance shall be performed with the breaker in
an upright position. Circuit breakers shall have self-contained
wheels designed for easy insertion, removal and transport on
flat indoor surfaces.
