MS132-6.3 4-6.3A

The ABB MS132‑6.3 Manual Motor Starter is a compact electromechanical protection device used for manual motor control and protection in industrial and commercial applications. It combines motor ON/OFF switching with overload, short‑circuit, and phase failure protection without requiring external fuses. The device is equipped with a rotary handle that clearly indicates the switch position (ON/OFF/TRIP) and can be locked to prevent unauthorized changes. It is designed for three‑pole (3P) applications and can be mounted on a standard DIN rail.
