Auxiliary contacts
Function
The auxiliary contacts control the contactor and signal overloads.
NC contact (NC 95-96) Disconnects the contactor, thereby protecting:
• The contactor
• The cables
• The load
NO contact (NO 97-98) Sends a signal, e.g. to the:
• Control system
• Lamp
• Other actuators
The contact rating of the auxiliary switches to be taken into account is specified in the
Technical data (Page 101).
