1SAM301901R1002

ABB 1SAM301901R1002 CK1-20 Short-Circuit Signaling Contact is a dedicated signaling accessory for ABB manual motor starters and motor protection applications. It incorporates two normally open (2NO) contacts and is used to provide remote indication when the associated motor starter trips specifically because of a short-circuit fault. The CK1-20 uses screw terminals and is mounted on the right-hand side of compatible ABB MS116, MS132 or MS165 manual motor starters. The device includes a protruding orange indicator button for local fault indication. Following a short-circuit trip, its contact position must be manually reset by pressing the orange button.
