PKZM0-0.63-T Eaton Motor Protective Circuit Breaker

The Moeller PKZM0-0.63-T is a manually operated motor protective circuit breaker intended for inductive loads with elevated starting current. Its adjustable thermal setting spans 0.4–0.63A, while the magnetic release trips at 11.97A, providing overload and short-circuit protection for three-phase motor circuits in demanding environments. The device carries a 50kA short-circuit current rating at 600V AC. Its 0.63A rating and 3P configuration match the specified motor protection application. UL listing and CSA certification allow use in group installations under NEC 430-53 and CEC Rule 28-206. This approval can eliminate the need for separate motor branch circuit protection, reducing installation cost and control-panel space requirements while maintaining compliance and safety.
