About Motor Contactors

Motor contactors are relays with large current capacity for connecting and disconnecting motors from power supplies. Most motor contractors are multi-pole devices in order to control all of the current-carrying conductors. Typically, motor contactors are set to a predetermined load value. When the maximum load value is crossed, the overload protection device opens the motor starter control circuit and turns off the motor. For best results, motor contactors should be durable, high-quality, long-lasting devices.
