Signaling switch
4.9.4.1
Description
Function
The signaling switch has two contact systems:
●
One contact system (1 NO c 1 NC contact) signals general tripping irrespective of
whether this was caused by a short circuit, an overload, or an auxiliary release.
●
The other contact system (1 NO contact and 1 NC contact) only switches in the event of
short-circuit release.
To be able to reclose the motor starter protector after a short circuit, once the cause of the
error has been dealt with, the signaling switch has to be reset by hand.
