PKZM0-0.63 Eaton Motor Protective Circuit Breaker

The PKZM0-0.63 is a manual motor protective circuit breaker from Moeller, intended to protect small motors against overload and short-circuit conditions. Its thermal setting is adjustable from 0.4–0.63A, allowing selection within the motor’s nameplate full-load current range, while the 8.8A magnetic trip provides short-circuit protection. The device has a 50kA short-circuit interrupting capacity at 600V AC and can be used with fuses or breakers rated up to 600A. It is UL listed and CSA certified, and it supports group installations under NEC 430-53 and CEC Part 1, Rule 28-206. This installation arrangement can reduce wiring costs and panel space requirements for industrial motor circuits.
