The Moeller PKZM0-25/AK is a manual motor protective circuit breaker for overload and short circuit protection. Its 25 A, 3P configuration includes an adjustable thermal range of 20–25 A and a magnetic trip response of 350 A, allowing protection to be set according to motor full-load current ratings. The device has a 10 kA short circuit current rating at 600 V AC and is approved with fuses up to 150 A or breakers up to 125 A. It is rated for 7.5 HP at 230 V and 15 HP at 460 V. UL listing and CSA certification support its use in industrial motor circuits, while approvals for group installations under NEC 430-53 and CEC rule 28-206 permit eliminating individual branch circuit protective devices in industrial control panels, reducing cost and space requirements.
