ABSTRACT:
A contactor includes an actuator which is slidably mounted to a base and carries a set of movable contacts into engagement with a set of stationary contacts when an associated electromagnet is energized. The stationary contacts are located above the electromagnet and are connected to a set of contactor input terminals and a first set of contactor output terminals which extend through the top of the contact enclosure. A second set of contactor output terminals are mounted to the base below the electromagnet where they are easily connected to overload relays. A set of bus bars are mounted to the base and connect the first and second set of contactor output terminals.
