Eaton M22-CKC01 Contact Element, 1 NC, Momentary, Front Mount, Screw Terminals

For control circuits that demand a dependable break, the M22-CKC01 contact element from Eaton's M22 series delivers a single normally closed contact in a compact, front-mountable module. Unlike generic auxiliary contacts that wear quickly under frequent switching, this unit is built to the IEC/EN 60947-5-1 standard and carries UL/CSA approvals, so it fits seamlessly into professional pushbutton and selector switch assemblies. The momentary action returns the contact to its resting state as soon as the actuator is released, making it ideal for stop functions, status feedback, and interlocking tasks.

Highlights

• One normally closed (NC) contact for breaking control signals
• Front mounting for fast, tool-light installation into M22 actuators
• Screw terminals accept solid or stranded conductors from 0.5 to 2.5 mm²
• Rated up to 500 V AC insulation voltage and 6 kV impulse withstand
• Wide operating temperature range from -25 °C to +70 °C

In daily use

Snap the M22-CKC01 onto any M22 pushbutton, selector switch, or illuminated actuator and you have a complete control station without extra wiring blocks. The screw terminals are angled for easy access, and the IP20 terminal protection is standard for enclosed panels. With a rated operational current of 6 A at 230 V AC (AC-15) and 3 A at 24 V DC (DC-13), it handles both inductive and resistive loads found in motor starters, relays, and PLC inputs. The contact's positive opening mechanism ensures the NC circuit opens even if the contacts weld, a critical safety feature for emergency stop applications.
