Manual Motor Starters

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. Fuseless 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.
