PKZM0-20/AK Eaton Motor Protective Circuit Breaker

The Moeller PKZM0-20/AK is a manual motor protective circuit breaker with a 20A rating and 3P construction for motor circuit protection. Its adjustable thermal range of 16–20 A coordinates with motor full-load currents, while its magnetic trip response of 280 A addresses short-circuit conditions. The short circuit current rating is 10 kA at 600 V AC, with approved use with fuses up to 150 A or breakers up to 125 A. Rated at 5 HP for 230 V motors and 10 HP for 460 V motors, the PKZM0-20/AK is UL listed and CSA certified. It supports group installations under NEC 430-53 and CEC rule 28-206, reducing the need for individual motor branch protection and helping optimize panel space and cost in industrial control panels.
