PKZM0-32 Eaton Motor Protective Circuit Breaker

The PKZM0-32 from Moeller is a manual motor protective circuit breaker rated at 32A and configured as a 3P unit for motor circuit protection. Its thermal overload setting is adjustable from 25–32A, allowing alignment with the connected motor’s full-load current rating, while the magnetic trip response is 448A for short-circuit protection. The device carries UL and CSA approvals and is suitable for group installations under NEC 430-53 and CEC Part 1, Rule 28-206. For these applications, group installation can eliminate the need for individual protective devices, reducing installation cost and panel space. The PKZM0-32 provides overload and short-circuit protection for industrial motor circuits.
