A contactor is a heavy-duty relay with higher current ratings, used for switching electric motors and lighting loads. Continuous current ratings for common contactors range from 30 amps to several hundred amps. High-current contacts are made with alloys containing silver. Contactors with overload protection devices are often used to start motors.
