As it name says Relay contacts gets locked when there is a fault in the circuit.And it is the kind of mechanical switch. Once fault is cleared then only we can able to make the circuit closed by resetting the latching pin in the relay manually.without clearing fault , it wont allow to energize the closing coil of the breaker(ACB) even though u try to reset.

What is the maximum advisable distance where it is required to interconnect a 500 KVA 480 V 3 ph transformer and the main panel or MCC ignoring the voltage droop affectation, does it is exist any standard about it?
