3.
Ground fault current is vector sum of each phase current.
Therefore, 3 Pole products may operate under its phase-
unbalance including in a ground fault situation.
4.
When ZSI function is set, the protection operation will take place
instantaneously with the 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)

Remote reset and digital I/O (A, P, S types)
In case of that MCCB 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.
3. Digital output 3a(524, 534, 544-513)
- Fault output: Long/Short time delay, Instantaneous, Ground fault, UVR, OVR, UFR,
OFR, rPower, Vunbal, Iunbal
(Maintains state as Latch form until user pushes reset.)
- General DO: when setting L/R as remote, it is available to control close/open
remotely by using communication.

ZSI- Zone Selective Interlocking (A, P, S type)
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 MCCB 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.
