1SAM201903R1001

ABB 1SAM201903R1001 SK1-11 Signaling Contact is a side-mounted signaling accessory designed for ABB manual motor starters and motor protection applications. It incorporates one normally open (1NO) and one normally closed (1NC) contact and uses reliable screw-terminal connections. The SK1-11 specifically signals when the manual motor starter has tripped, regardless of whether the trip was caused by a short circuit, overload, or an electrical release such as AA1 or UA1. A protruding orange indicator button provides local visual trip indication. After a trip event, the signaling contact must be manually reset by pressing the orange button.
