A main contact movable member operates to perform closing or interrupting by attraction or release of the movable core with respect to the fixed core. The actuator has a trip spring, energy-stored during the closing, that performs the interrupting upon stopping energization to the holding coil and thereby releasing the stored-energy. The actuator has an auxiliary contact operating with the operation of the movable core and performing energization switching with respect to the closing coil and the holding coil. The trip spring is provided on one side of the electromagnet in a horizontal direction while the auxiliary contact is provided on the other side.
