The CK safety critical, weld resistant and safety critical relay has 9 double break contacts (Form X & Y - per customers specification) in all NO and NC combinations. Weld no transfer and silver tin oxide safety contacts are standard. The plug-in design offers secure locking feature for maximum ease of maintenance (no wires need to be disconnected or other hardware removed for relay inspection or replacement).

The resistance to impact and vibration is conforming the standards for Railway Transported Equipment. Positive mechanical keying of relay to socket is built into relay and socket during manufacture and terminal identifications are clearly marked on identification plate that is permanently attached to the relay. In power interruption situation relay armature will assume a “safe” position whatever is the relay operating position due to the strength of the 1 compressed spring which pushes the armature back in the rest position.

The CK relays is pluggable in the COR NJ socket.
