Motor protection and control catalog

Manual motor starters, contractors, and overload relays

Manual motor starters are electromechanical protection devices for the main circuit. They are used mainly to switch motors manually ON/OFF and to provide fuse-less protection against short-circuit, overload and phase failures. Fuse-less protection saves costs, space and ensures a quick reaction under short-curcuit condition by switching the motor off within milliseconds.  Starter combinations are setup together with contractors.
