Abstract
Disclosed is a magnetic contactor. The magnetic contactor includes a frame, a holder, a movable core, a bobbin, a fixed core coupled to a side of the bobbin and configured to absorb the movable core with a magnetic force, an elastic member provided between the holder and the bobbin, a b-contact switch configured to sense a closing completion time of the movable contact by using a mechanical mechanism relationship with the movable core, an electronic circuit part configured to receive a sensing signal from the b-contact switch and limit a current applied to the coil, and a switch manipulation member provided at one end of the movable core and configured to operate the b-contact switch.
