MS116-0.25 Manual Motor Starter
The MS116-0.25 manual motor starter, also known as motor protection circuit breaker or manual motor protector, is a compact 4.5 cm width device with a rated operational current of Ie = 0.25 A. It is designed to manually switch on and off motors and provide reliable protection without the need for a fuse, against short-circuits, overload, and phase failures.
The starter offers a rated service short-circuit breaking capacity (Ics) of 50 kA at 400 VAC and trip class 10A. Features include a built-in disconnect function, temperature compensation, trip-free mechanism, and a rotary handle with clear ON/OFF position indication. Suitable for both three- and single-phase applications.
Auxiliary contacts, signaling contacts, undervoltage releases, shunt trips, 3-phase bus bars, power in-feed blocks, and locking devices for protection against unauthorized changes are available as accessories.
