A contactor is an electrically controlled switch used to switch an electrical circuit on or off. It is considered a special type of relay. However, the basic difference between relays and contactors is that contactors are used in applications with higher current carrying capacity whereas relays are used in lower current applications. Contactors can be easily field installed and are compact in size. Typically, these electrical devices have multiple contacts. These contacts are normally open most of the time and provide operating power to the load when the contactor coil is energized. Contactors are most commonly used to control electric motors.
