PKZM0-10/AK Eaton Motor Protective Circuit Breaker

The PKZM0-10/AK is a manual motor protective circuit breaker from Moeller, intended to protect motors from overload and short-circuit conditions. Its adjustable thermal range spans 6.3–11 A, while the magnetic trip responds at 140 A for coordination with motor full-load currents. The device carries a 22 kA short-circuit current rating at 600 V AC and can be coordinated with fuses rated up to 150 A or circuit breakers rated up to 125 A. Rated for 3 HP at 230 V and 7.5 HP at 460 V, this 10 A, 3P unit is UL listed and CSA certified for group installations under NEC 430-53 and CEC rule 28-206, supporting reduced use of separate motor branch-circuit protective devices in industrial control panels and helping reduce cost and space requirements.
