Product Information
Extended Description
1SAM301901R1002 ABB: 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.

FAQs
The CK1-20 signaling contact is designed for ABB CK1 accessories and pairs with MS116, MS132, and MS165 manual motor starters. It uses screw terminals for robust wiring and provides two normally open contacts to indicate short-circuit trips.
It is rated for up to 690 V AC main circuit (600 V DC) with IP20 protection, two normally open auxiliary contacts, and screw-terminal connections. The device supports durable operation with up to 10,000 electrical cycles and is RoHS/REACH compliant.
After a short-circuit trip, the CK1-20 requires a manual reset by pressing the protruding orange button located on the signaling contact. This ensures deliberate restart and avoids inadvertent re-tripping.
Yes. The CK1-20 carries CE and UL/CSA certifications, with RoHS and REACH declarations, and supports multi-region installations including UKCA and other relevant standards for industrial automation equipment.
By delivering clear visual signaling of tripping events, reducing downtime and speeding fault isolation, the CK1-20 lowers MTTR. Its compact form, durable wiring, and compatibility with MS starters help achieve safer, more reliable motor protection and greater maintenance productivity in automation lines.
