Moeller PKZM0-2,5 Motor Protection Circuit Breaker

The Moeller PKZM0-2,5 Manual Motor Starter Protector is a 3-pole thermal-magnetic motor protection circuit breaker designed to provide manual switching, overload protection, short-circuit protection, and phase-failure protection for three-phase motors. It offers a current adjustment range from 1.6 to 2.5 A with a rated operational current (Ie) of 2.5 A and a rated operational voltage up to 690 VAC. The device accommodates motor ratings of 0.37 kW at 230 VAC, 0.75 kW at 400 VAC, 1.1 kW at 440/500 VAC, and 1.5 kW at 690 VAC, and features a trip class of 10A. Short-circuit capability is 150 kA (Icu) at 400 VAC, with a fixed short-circuit release of 15.5 × Iu (about 38.8 A). Protection functions include thermal overload, magnetic short-circuit, and phase-failure protection. It can be mounted on 35 mm DIN rails or panel-mounted, with screw-terminal connections, and provides IP20 protection at the device and IP00 at the terminals. This MMS is intended for industrial motor control in conveyors, pumps, compressors, HVAC equipment, and other equipment requiring reliable motor protection and control, and is commonly used by maintenance teams and system integrators for replacement, retrofit, and expansion in OEM machinery and electrical panels. Manufacturer is Klockner Moeller / Eaton in the PKZM0 series (MPN PKZM0-2,5 / PKZM0-2.5). Common replacements include Eaton XTPR2P5BC1NL, Schneider Electric GV2ME07, and ABB MS116-2.5.
