Signal contact SK1-02

ABB SK1-02 — Signaling contacts SK1 with screw terminals signal the tripping of the manual motor starter. For SK1 the indication on the device itself is done with a protruding orange button. The contact positions of SK1 need to be manually reset after a tripping event by pushing the orange button. SK1 signaling contacts signal tripping regardless if it was caused by short-circuit, overload or electrical release (AA1 or UA1). They are attached on the right side of the manual motor starter. Signaling contacts SK1 are available as normally open or normally closed contacts.
