Description
Signaling contacts CK1 with screw terminals signal the tripping of the manual motor starter in case it was caused by a short-circuit. For CK1 the indication on the device itself is done with a protruding orange button. The contact positions of CK1 need to be manually reset after a tripping event by pushing the orange button. They are attached on the right side of the manual motor starter MS116, MS132 or MS165. Signaling contacts CK1 are available as normally open or normally closed contacts.
