Manual motor starters (MMS) are protection devices for the main circuit. They combine motor control and protection in a single device. MMS are used mainly to switch motors manually ON/OFF and protect them and the installation fuse less against short-circuit, overload and phase failures. Fuse less protection with a manual motor starter saves costs, space and ensures a quick reaction under short-circuit condition, by switching off the motor within milliseconds. MS116 is a compact and economic range for motor protection up to 15.5 kW (400 VAC)/32 A in width of 45 mm. Further features are the build-in disconnect function, temperature compensation, trip-free mechanism and a rotary handle with a clear switch position indication. The manual motor starter is suitable for three and single-phase applications. Auxiliary contacts, signaling contacts, under voltage releases, shunt trips, three phase bus bars, power in-feed blocks and locking devices for protection against unauthorized changes are available as accessory.
