The ABB MP2‑41R‑10 is a manual motor protector (MMP) designed to provide reliable motor overload, short‑circuit, and phase‑failure protection for electric motors in industrial and commercial applications. It combines a thermal overload trip element with an instantaneous magnetic trip and an ON/OFF/R (reset) rotary operator, enabling manual motor starting and stopping as well as automatic protection. The protector is suitable for use on three‑phase motors and offers adjustable trip settings to match the motor’s rated current. With its rugged construction, compact footprint, and clear status indication, the MP2‑41R‑10 is ideal for motor control centers, machinery, pump systems, compressors, and general three‑phase motor circuits.
