What is it fast earthing or CB spring?
Hi. Fast Earthing switch or same earthing switch but we have different in fast the first rated short-circuit closing current pick is high discharge 2. Operation mechanism type is spring 3. The last device in circuit.❤are you anderstand?
And then it can be used to test mechanical properties of the measurement circuit breaker of the main circuit resistance.
