What is mechanical interlock?Explain the uses?
Answer Posted / guru
Its is otherwise termed as Castel Key Interlock.
The primary function of this type of interlock we can
provide many mechanical locks in between the circuit
breakers or isolators but all the locks cane be opened only
with a single key. So if a key is engaged in a isolator or
breaker without shutting down of that breaker that key
cannot be removed and unlock the other cicuit breaker to
switch it on. By this way any mistake of operating 02
circuit breakers operating simultaneously is avoided.
