    Contactor basics.

    Contactors are used throughout electrical systems and control panels to switch and control circuits in lighting systems, motors, heating and HVAC systems and more. Every contactor is controlled by a circuit and connected to a high current device, unlike relays. Both IEC contactors and NEMA contactors are available though NEMA contactors are considered the North American standard, and while IEC contactors are used globally, they are more popular in Europe.

    Not all contactors are created equal.

    All contactors perform the same essential function but different types of contactors vary from application to application. For example, HVAC and furnace contactors work differently than winch contactors. In HVAC systems, the contactors receive voltage from the building’s thermostat to either heat up or cool down. When the thermostat stops delivering voltage, it the contactor opens and the AC unit shuts down. A winch contactor is designed specially for applications involving winches and heavy lifting, which rely on a different type of motor.

    Contactors are rated using a number of factors including coil voltage, voltage, lifespan, load current and duty cycle. Voltages for compressor contactors and furnace contactors can vary anywhere from 24 VAC to 240 VAC,
