ABB MS132-0.25 interruttore di protezione motore - 0,16-0,25 A, 3 poli, classe 10, 690V

Protecting small motors from overload and short circuits is critical in industrial control panels. The ABB MS132-0.25 manual motor starter delivers reliable protection for motors up to 0.06 kW at 400 V, with a precise thermal overload setting range of 0.16 to 0.25 A. Its compact 45 mm width saves space on the DIN rail while offering robust performance.

Who is it for

This motor starter is ideal for panel builders, maintenance technicians, and OEMs who need a compact, high-breaking-capacity protection device for small three-phase motors in applications such as pumps, fans, conveyors, and machine tools. It is suitable for use in industrial environments where reliable motor protection and quick installation are essential.

Tips

Always set the thermal overload dial to the motor's full-load current as indicated on its nameplate. For reliable protection, ensure the short-circuit current at the installation point does not exceed the device's breaking capacity. Use appropriate screwdrivers and torque settings when connecting conductors to maintain IP20 protection and prevent overheating.
