simply saying,
RELAY consists of coil wounded on core and a contactor
If you saw a construction of MCB, an arrangement similar to
relay is made with nc contact and an external switch.
During normal operation, current flows through MCB relay
coil is not sufficient to change the position of contactor,
But on faulty condition, the fault current flows through
the MCB relay coil is sufficient to change the position of
contactor as from nc to no.
r u got it.
