Product questions
What does the ABB SK1-02 signaling contact indicate?
The SK1-02 signals that a manual motor starter has tripped, including trips caused by overload, short circuit or an electrical release. It is a signaling accessory, not a motor starter.

The SK1-02 has two normally closed auxiliary contacts and no normally open contacts. It uses screw terminals.
How does the SK1-02 indicate and reset after a trip?
A protruding orange button provides a local trip indication. The signaling contacts require manual reset using that button after a trip.
Where is the SK1-02 mounted and how much space does it need?
It attaches to the right side of the manual motor starter. The contact block measures 9 mm wide, 90 mm high and 78.5 mm deep. Confirm the starter model and available clearance before ordering.
