They generally offer feedback on the status of the motor control centres (MCC) & the connected motor for easy control of external devices like alarms or safety interlocks. These auxiliary contact...s are mostly mounted in a contactor or starter to control & monitor their operation. They come in normally open (NO), normally closed (NC) and combination (CO) configurations.Read more
