A contactor is an electrically controlled switch to turn on a circuit of electric current, similar to a relay except with higher current levels apart from some other differences.
Relays are used when it is necessary to control a circuit by a differentiated high-intensity signal, or when several circuits have to be controlled by a single signal. The type of relai capable of withstanding this high intensity to directly control an electric motor and other loads, is a contactor.
