PKZM0-6.3-T Eaton Motor Protective Circuit Breaker

The PKZM0-6.3-T from Moeller is a manual motor protector intended for motors and inductive loads that experience elevated inrush current. Its three-phase construction, rated at 6.3A, includes adjustable thermal overload protection over a 4–6.3A range and a magnetic trip response of 141A. A short-circuit current rating of 22kA at 600V AC identifies the unit’s suitability for the specified industrial voltage application. The product is UL listed and CSA certified and meets NEC 430-53 and CEC Rule 28-206. Those standards permit its use in group installations without separate branch-circuit overcurrent protection for each motor, supporting reduced wiring complexity, smaller panel space requirements, and lower installation costs while preserving safety and code compliance.
