Overload switches protect the motor in your compressor from becoming overpowered by high amounts of electrical current. This switch is designed to trip when the motor receives too much power, opening the circuit and preventing the motor from overheating. This means that both your compressor and your unit are in danger if you have a faulty overload. With a variety of overloads to choose from, you can be confident we have the one you need to get your unit running again.
