ABB MS132-1.0 Manual Motor Starter

ABB MS132-1.0 Manual Motor Starter, model 1SAM350000R1005, is a compact 45 mm-wide, 3-pole manual motor protector that combines overload protection with a disconnect function for motor circuits. Rated for up to 480–600 V AC and designed for both three- and single-phase applications, it provides an adjustable overload setting with a rated operating current of Ie = 1.0 A and a setting range around 0.63–1.0 A; the overload protection uses trip class 10. The device is UL 508-listed as a Manual Motor Controller and features ON/OFF/TRIP action, a lockable handle, and clear switch position indication, making operation unambiguous in control panels. For group installations, it supports branch-circuit protection with a maximum circuit-breaker rating of 250 A at 480/600 V, consolidating protection and disconnection in one unit. Designed for use as a motor disconnect in small to mid-size motor circuits, the MS132-1.0 is a practical, space-efficient solution where a dedicated motor protector and disconnect are required in one compact package.
