ABB MS132-20 Manual Motor Starter

ABB MS132-20 Manual Motor Starter is a compact 3‑pole motor protection and control device, 45 mm wide, designed to protect and manually start small to mid‑size motors inside electrical panels. It provides overload protection with a rated operational current Ie of 20 A and a trip class 10, with a protection setting range of 16–20 A for the motor circuit. The MS132-20 supports a main circuit voltage up to 690 V AC or 250 V DC and is rated for 50/60 Hz operation, delivering 15 hp (about 9 kW) at full load in a three‑phase setup. Dimensions are 97.8 mm high, 45 mm wide, and 86.6 mm deep, and it comes in an IP20 enclosure with a rotary ON/OFF/Trip handle for straightforward manual control; electrical connections use M4 screw terminals for MS132-20, -25, -32 variants. Operating temperature range is -25 to 70 C, making it suitable for industrial panels, and it is designed for UL 508 listed manual motor controller applications. Commonly used in pumps, conveyors, fans, and other motor‑driven equipment to provide integrated overload and short‑circuit protection in three‑phase circuits.
