The ABB MS325‑9 Manual Motor Starter is a three‑pole electromechanical protection device used for manual control (ON/OFF) and protection of electric motors and associated circuits. It combines manual switching with overload, short‑circuit, and phase‑failure protection without the need for external fuses. The device includes a rotary handle with clear position indication, a trip‑free mechanism, and built‑in disconnect functionality. It is suitable for both three‑phase and single‑phase applications and can accommodate add‑on accessories such as auxiliary contacts, signalling contacts, undervoltage releases, shunt trips, and locking devices.
