WEG MPW40-3-U010 Manual Motor Protector 6.3-10A 3-Pole 690V Breaker

The WEG MPW40-3-U010 is a 3-pole manual motor protector (motor-protective circuit breaker) with a rotary handle and an adjustable 6.3–10A thermal overload setting range. Designed to provide combined short-circuit and overload protection for electric motors, it features high interrupting capacity for installations with high short-circuit current levels, phase-failure sensitivity, and trip indication that lets the operator visually confirm breaker status. The rotary handle can be padlocked in the OFF position for safe maintenance lockout.
