What is the difference between a circuit breaker and an isolating switch?

Today we will explain the difference between a circuit breaker and an isolating switch.

1. Circuit breakers and isolating switches are both main circuit switching appliances and distribution appliances.

2. The isolating switch is a passive component, and the circuit breaker is an active component.

3. The task of the isolation switch is to construct a clear breakpoint in the circuit, that is, to achieve the isolation task in the disconnected state.

4. Both the circuit breaker and the isolating switch must have the ability to withstand the electric power impact generated by the peak short-circuit current lpk, and both must have the ability to withstand the thermal shock of the short-circuit current within a certain period of time.
