Distinguish the circuit breaker in one second due to leakage trip or short circuit trip
After the circuit breaker trips, whether we are planning to repair or intend to attempt to close, we must know the reason for the last trip to narrow the suspected range. The circuit breaker has two major protection functions - overload (short circuit is a special form of overload) protection and leakage protection. So how do we know if the circuit breaker is due to an overload trip or a trip due to leakage? In fact, observing the circuit breaker after the trip can be recognized at a glance.
