The PKZM0-0.25/SP is a 3-pole manual motor protective circuit breaker rated at 0.25 A. It provides adjustable thermal overload protection across a range of 0.16–0.25 A and fixed magnetic short-circuit protection at 3.5 A. Certified to UL and CSA standards as a Type E self-protected combination controller, it integrates overload protection, short-circuit protection, manual disconnect, and controller functionality. Approved for group installation per NEC and CEC requirements, it supports use in grounded Wye power systems with voltages exceeding 240 V. The device is compatible with magnetic contactors for remote operation and eliminates the need for separate fuses or circuit breakers in motor control applications.
