PKZM0-1.6/AK Eaton Motor Protective Circuit Breaker

The PKZM0-1.6/AK is a manual motor protector from Moeller designed to protect motors against overload and short circuit conditions. Its adjustable thermal setting spans 1–1.6 A, allowing selection according to the motor nameplate full load current, while the magnetic trip responds at 22 A. The device is rated for 3P operation and provides a 50 kA short circuit current rating at 600 V AC. It accommodates branch circuit fuses or breakers rated up to 600 A for industrial motor applications. For a 3/4 HP motor at 230 V, it is UL listed and CSA certified for group installations under NEC 430-53 and CEC rule 28-206, which permits group installation without individual branch protection and can reduce panel space requirements and installation costs.
