The ABB MS132‑20 (1SAM350000R1013) is a compact manual motor starter / motor protection breaker designed to manually start and stop small motors and provide built‑in protection against overload, short‑circuit, and phase failure without requiring separate fuses. It is suitable for three‑phase and single‑phase motors and is commonly used in control panels, machinery, and industrial and commercial motor protection applications. The device features a thermo‑magnetic tripping mechanism, a rotary handle with clear ON/OFF/TRIP indication, and a lockable handle for safety.
