Trip Relay
(OCR)
Trip relays are classified according to function.
Trip relays are classified according to their usages and functions to maximize
customers’ satisfaction. Classified trip relays and easy installation.
�Protection: overload, short current, ground fault, earth leakage, under voltage, over voltage,
under frequency, over frequency, reverse power, unbalance, etc
�Measurement: voltage, ampere, power, energy, frequency, power factor, harmonics, etc.
�Event & fault recording: Max. 256 events & faults
�Communication: Modbus/RS-485, Profibus-DP
Susol ACB Trip Relay functioning world-best protection can be interlocked with mechanism.
It makes the breaking capacity of ACB improved and ACB’s life enhanced, and provides
advanced functions - measurement, diagnosis, analysis, and communication.

Trip relay(OCR)
The trip relay of Susol ACB provides the additional protection functions for
voltage, frequency, unbalance, and others in addition to main protection
functions for over current, short-circuit, ground fault. It supports the
advanced measurement functions for voltage, current, power, electric energy,
harmonics, communication function, and others.
Analog trip function interlocked with mechanism enhanced a durability of
devices as well as the breaking capacity of ACB.
Zone selective interlocking function makes the protective coordination more
simple and thermal memory can be applied to various loads.

Ground Fault (G)
The function for breaking ground fault current above setting value
after time-delay to protect the circuit from ground fault.
1. Standard setting current knob: Ig
- Setting range: (0.2-0.3-0.4-0.5-0.6-0.7-0.8-1.0-Off)×In
2. Time delay setting knob: tg
- Inverse time (I2t On): 0.1-0.2-0.3-0.4 sec
- Definite time (I2t Off): 0.05-0.1-0.2-0.3-0.4 sec
3. Ground fault current is vector sum of each phase current. Therefore, 3Pole products may operate
under its phase-unbalance including ground fault situations.(R+S+T+(N) Phase)
4. When ZSI function was set, the protection operation will take place instantaneously with input absence
by downstream devices. It is advised to disable its ZSI function on the last downstream device.
5. Ground-fault functions are basically provided with products equipped with a trip relay through its
internal CT that is embedded in each phase.(But, it can’t be used with earth-leakage protection
function at the same time)

Earth Leakage (G) - Option
The function for breaking earth leakage current above setting value after
time delay to protect the circuit from earth leakage. (A, P, S type)
1. Standard setting current knob: I△n
- Setting range: 0.5-1-2-3-5-10-20-30-Off (A)
2. Time delay setting knob: △t
- Trip time: 140-230-350-800 ms
- Alarm time: 140-230-350-800-950 ms
3. Settings within its alarm range will prevent its breaker from tripping but activating its alarm.
4. This function is enabled and can be used only with private external CT(secondary output 5A)
selected by customers.
5. When ZSI function was set, the protection operation will take place instantaneously with input
absence by downstream devices. It is advised to disable its ZSI function on the last downstream
device.

- When using other CT selected by customers, the setting range is from 0.5 to 5A based on its
secondary current.(Secondary output rating : 5A)
Hence, under 100:5A CT, if trip relay is set to 0.5A, earth-leakage exceeding 10A will activate its
operation (0.5A×20 = 10A)
ZCT or External
CT
※Guideline for the external CT usage
- Earth-leakage protection characteristics using the standard CT which is installed inside of ACB can
protect currents from 20 to 100% range on its rated current.
- As rated currents on ACB increases, current that is covered by its standard CT increase as well.
This can not protect against small leakage currents.
ex) 400A ACB Min. Earth-leakage current 400A×20% =80A
4000A ACB Min. Earth-leakage current 4000A×20% =800A
- Therefore, customers are advised to install an external CT in accordance with its rated currents
within its systems. And choose trip relay(E, X type) which is required with external CT usage in
order to provide earth-leakage functions.

ZSI - Zone Selective Interlocking (A, P, S type)
Zone-selective interlocking drops delay time that eliminates faults for breakers.
It minimizes the shock that all kinds of electric machineries get under
fault conditions.
1. 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.
2. To eliminate a breakdown, trip relay of ACB at accident site activates trip operation
without time delay.
3. 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.
4. 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.
5. ZSI connecting line needs to be Max. 3m.

1) Occurrence of fault A
- Only breaker ① performs instantaneous trip operation.
2) Occurrence of fault B
- Breaker ② performs instantaneous trip operation,
breaker ① performs trip operation after prearranged delay time
- But if breaker ② did not break the fault normally,
breaker ① performs instantaneous trip operation to protect system.

Remote reset and digital I/O (A, P, S type)
In case of that ACB operates due to accidents or over current,
Trip relay indicates the information of the accident through the LED and LCD.
Trip relay A, P and S type is possible to perform the remote reset by digital input,
and have 3 DO(Digital output).
1. Methods to reset Trip relay is to push the Reset button on the frontal side and to
use the remote reset.
2. Digital input
- [R11-R22] input: Remote reset
- [Z1-Z2] Input: ZSI input
- [E1-E2] Input: ZCT for earth leakage detection or external CT input
※All DI are dry contact that has 3.3V of recognition voltage. When inputting close by
SSR(Solid State Relay) or open-collector, connect collector(Drain) to R11.

Trip Alarm Contact [AL]
�When a circuit breaker is tripped by OCR which operates against the fault current
(Over Current Relay), Trip Alarm switch provides the information regarding the trip of circuit
breaker by sending the electrical signal from the mechanical indicator on front cover of main
circuit breaker or internal auxiliary switch. (Installed at the inside of circuit breaker)
AL1, 1a
AL2, 1a
�When a circuit breaker tripped by fault current, a mechanical trip indicator
(MRB, Manual Reset Button) pops out from the front cover and the switch (AL) which sends
control signal electrically is conducted to output the information occurred from fault circuit
breaker.
�MRB and AL can be operated only when tripping by OCR,
but doesn’t be operated by Off button and OFF operation of trip coil.
�To re-close a circuit breaker after a trip, press MRB to reset it for closing.
�2pcs of electrical trip switch (AL1, AL2, 1a) are provided (Option)
�Trip alarm contact and MRB(Manual reset bottom) need to be purchased together.
