摘要： There is provided an electromagnetic contactor such that it is possible to reduce the energizing current flowing to a coil, and to reduce the overall size. An electromagnet unit that drives a movable contact disposed so as to be connectable to and detachable from fixed contacts includes at least a movable plunger biased by a return spring, a coil (208) that enables the movable plunger to move, and a ring-form permanent magnet, magnetized in the direction in which the movable plunger is movable, disposed and fixed so as to enclose a peripheral flange portion formed on the movable plunger. A drive circuit (300) that drives the coil (208) includes a power source that supplies power to the coil (208), a pulse drive circuit (305) that outputs and supplies to the coil (208) an engage pulse that causes an operation suctioning the movable plunger and a hold pulse that, when the movable plunger is subjected to a suctioning operation by the engage pulse, maintains the suctioning operation, and a flywheel circuit (310), (320) having a semiconductor switching element (Tr2) connected in parallel to the coil (208).
