PKZM0-20-T Eaton Motor Protective Circuit Breaker

The PKZM0-20-T from Moeller is a manual motor protective circuit breaker intended for three-phase motor circuits with inductive loads and elevated inrush current. It combines overload and short-circuit protection with an adjustable thermal setting spanning 16–20A and a magnetic trip at 380A. Its 20A rating and 3P configuration suit motor applications requiring three-pole protection. The device carries a 10kA short-circuit current rating at 600V AC and is UL listed and CSA certified for group installations under NEC 430-53 and CEC Rule 28-206. This certification permits its use without separate motor branch circuit overcurrent devices, helping reduce panel space and installation complexity while supporting applicable safety and compliance requirements.
