Eaton 216378 M22-K01 Contact Element 1NC Screw Terminals

The Eaton M22-K01 is a front-mounting break contact element from the Moeller M22 series, providing 1 normally closed (NC) contact for control circuit monitoring, interlocking, and signal duties. Rated at 6 A at 220-240 V AC and 3 A at 24 V, it connects via screw terminals and clips directly to the front of compatible M22 operators. The compact 32 x 10 x 38 mm housing suits space-constrained control panel layouts.
