PKZM0-0.4/AK Eaton Motor Protective Circuit Breaker

The Moeller PKZM0-0.4/AK is a compact, manually operated 0.4A, 3P motor protective circuit breaker designed for overload and short-circuit protection. Its adjustable thermal range spans 0.25–0.4 A, while the magnetic trip responds at 5.6 A, allowing selection according to motor full-load current. The device has a 50 kA short-circuit current rating at 600 V AC and is compatible with branch circuit fuses or breakers rated up to 600 A. It is UL listed and CSA certified for group installations under NEC 430-53 and CEC rule 28-206. This arrangement supports industrial motor circuits without requiring individual motor branch overcurrent protection, reducing both cost and panel space while maintaining full compliance with electrical standards.
