Answer Posted / vikas s adhatrao
TNC switch is a three position switch, used for closing or
tripping a circuit breaker manually from panel (locally).
this switch is spring loaded, this ensures that switch
returns to neutral position after any operation (either
close or trip). This is required to isloate the closing /
trip coils, which are short time rated, from the control
supply.TNC switch makes close open commands momentary.
