Product Description
Has the selection of the three section protective current, actuation time: user can set and adjust the
tripper according to the load current;
Self-powered: the circuit breaker provide the energy to electronic tripper by itself, the current signal
and tripper operating power are from the current mutual inductor inside the circuit breaker;
“Pre-alarm” indication: when the actual operating current through the circuit reach or exceed the
pre-alarmed operating current lro, the “pre-alarm” LED on the circuit breaker cover become
yellow color;
Overload indication: when the load current exceed the overload long time delay operating current,
the LED on the circuit breaker cover become red color;
Large current instant tripping function: when the circuit on or during operation, in short circuit large
current (≥20lnm), the circuit release directly through the electromagnetic tripping mechanism;
Interchangeable installation: appearance dimension is same with the CMGM3E series moulded case
circuit breaker.
1. Selective coordination: CMGM3E electronic moulded case circuit breaker has the three sections protection function, use
category is B and have the selectivity coordination when connected with the other short circuit protection device in the same circuit;
2. Has the selection of the three section protective current, actuation time: user can set and adjust the tripper according to the load current;
3. Self-powered: the circuit breaker provide the energy to electronic tripper by itself, the current signal and tripper operating power are from the current mutual inductor inside the circuit breaker;
4. “Pre-alarm” indication: when the actual operating current through the circuit reach or exceed the pre-alarmed operating current lro, the “pre-alarm” LED on the circuit breaker cover become yellow color;
5. Overload indication: when the load current exceed the overload long time delay operating current, the LED on the circuit breaker cover become red color;
6. Large current instant tripping function: when the circuit on or during operation, in short circuit large current (≥20lnm), the circuit release directly through the electromagnetic tripping mechanism;
