| Zone selective interlock function |
Zone selective interlocking drops delay time that eliminates faults for breakers.
It minimizes the shock that all kinds of electric machinery get under fault conditions.
 Example
 In case of that short time-delay or ground fault accident occurs at ZSI built in system, the breaker at accident site
sends ZSI signal to halt upstream breaker’s operation.
 To eliminate a breakdown, trip relay of ACB at accident site activates trip operation without time delay.
 The
upstream breaker that received ZSI signal adhere to pre-set short time-delay or ground fault time delay for
protective coordination in the system. However upstream breaker that did not receive its signal will trip instantaneously.
 For ordinary ZSI operation, it should arrange operation time accordingly so that downstream circuit breakers will
react before upstream ones under overcurrent/short time delay/ground fault situations.
 ZSI connecting line needs to be maximum 3m.

| UVT coil |
•If the voltage of the main or the control power is
under 70% of the standard, UVT breaks the circuit
automatically.
•Connect instantaneous type with both terminals
(9,10) and connect with time delay type in order to
present time delay controller.
•- The circuit breaker is opened with trip unit power
supply voltages below 70%.
- The circuit breaker is closed with unit power supply
voltage above 85%.
•Instantaneous type can not be used with double trip
coil.

| UVT time delay controller |
•Use of UVT time delay controller is recommended to
prevent tripping when the power supply network for
the trip unit is subject to brief voltage drops or power
supply failures.
•This device is possible to delay as (0.5, 1.0, 1.5, 3 sec).
•It can be mounted at the left side of cradle or the DIN
rail.
•Controller is mounted at cradle (Draw-out type) or
outside of main body (Fixed type).

•Applicable AUX switch is up to 6a6b. Add AA on your order.
•When working with monitoring contact for trip coil the
AUX switch will be 3a3b. When working with OCR’s MCR
function it will be 4a5b. When both monitoring contact and
MCR function working together it will be 3a4b.
•When ordering short “b”additionally it will be attached to
‘b’contacts 51, 52 when the product is out. The additional
short b which enclosed in the product is applicable as the
number of the b contact.
•5a5b is separate product and available. Add UANS AS on

| Mechanical interlock kit |
•It is used to interlock closing and trip between two or
three breakers mechanically so as to prevent unintended
operation at the same time.
•The MI is a safety gear installed in ACB for distribution line
and it creates a mechanical interlock between two or three
circuit-breakers through each CB’s open/close work.
•To operate the MI every component linked to the MI unit
and the MI must be combined before use.
•MI unit is separate product. After installing ACB it is
additionally attached.
•When ordering B0 all components linked to the MI unit
are provided.
•Order other separate kits when having purchased only
ACB without B0.

| OCR & Alarm switch reset |
•When a circuit breaker tripped by fault current or over load
and only if the circuit breaker has been tripped by OCR, the
MRB operates interlock and resets the interlock to restore
electric lines after fault factors have been removed. -(BR)
•When the CB is tripped by OCR it provides functions of
interlocking above mechanism -(BR) and output contacts
(2a) which check operation of CB by OCR as well. The
output contact displays OCR operation by long time, short
time delay, instantaneous and ground fault. And resetting
above mechanism occurs. -(BA)
•Except above functions when emergent restoration of
electric load is needed it automatically reset itself to get
ready to open immediately after trip and reset only output
contacts. (BM)
•It will have been installed when the product is out. Add BR/
BA/BM on your order.

can occur when it reaches the specified temperature.
•Display the maximum temperature on the segment LED
and transmits through a network.
•Communicates with modbus/RS-485 basically, and needs
to be purchased separately.

•The NCT is additionally applied for 3-pole circuit breaker
when it is connected to distribution line (3 phases 4 lines).
•For distribution line (3 phases 4 lines) 3pole circuit
breaker can protect the ground fault however, we can not
classify unbalanced load and ground fault. To complement
this when only a ground fault occurs the NCT senses the
N phase load and operates the GFT.
•When connecting a relay or electric instrument checking
phase is mandatory. Please connect the designated
terminal.
•It is a separate product. Refer to the table below (Rated
current level) and check the item on your order.

•Stable transfer system
Provides definite protection for electric power system by
using Hyudai ACB which has the highest breaking capacity.
•An unmanned woking system
An unmanned automatically transfering system is realized
by installing auto power control device to the ACB with
mechanic interlock device.
•Various mode
Offers four selection modes for user's convenience.
