Product Description
The Moeller PKZMO-16 (PKZM0-16) is a three-pole thermal-magnetic motor protective circuit breaker (MPCB) from the Moeller PKZM0 series, now produced by Eaton. It provides integrated overload and short-circuit protection in a single compact unit, featuring an adjustable bimetal thermal trip range of 10–16A and a fixed magnetic trip response of 224A. The device mounts on a standard 35mm DIN rail, uses screw-clamp terminals, and is compatible with DILM frame-size B contactors for remote-control combination starter configurations.
