What is the function of trip neutral close switch?
Answer Posted / amit tiwari
It is as simple as TNC (Trip Neutral Close) in normal condition the switch will be in NEUTRAL position. To close the Circuit breaker we have to rotate it in direction 'C' as mentioned in TNC switch and breaker will be in operation and if we want to trip the circuit breaker we have to rotate the switch in the direction of 'T' as mentioned in TNC switch and breaker will get tripped for maintenance. Remember TNC will operate from field. Remote closing and tripping can be done as TNC switch will be in 'N' position.
