Description
MS116-25 Manual Motor Starter 20 … 25 A
The MS116-25 manual motor starter, also known as motor protection circuit breaker or manual motor protector, is a compact device with a width of 4.5 cm and a rated operational current of Ie = 25.0 A. This device is designed to manually switch on and off motors and protect them reliably without the need for a fuse from short-circuits, overload, and phase failures.
The manual motor starter offers a rated service short-circuit breaking capacity (Ics) of 10 kA at 400 VAC and a trip class of 10A. It features a built-in disconnect function, temperature compensation, trip-free mechanism, and a rotary handle with clear ON/OFF switch position indication. It is suitable for use in 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.
