CONTACTOR | HPX1985

contactor, Hayward HPX1985, is an electromechanical switch used in heat pumps, air conditioners, and other electrical devices to control the flow of electricity to high-power components like compressors, fans, and motors. 

• Control Signal Activation
• The thermostat or control board sends a low-voltage signal (typically 24 volts) to the contactor's coil for heating or cooling is needed.
• This signal energizes the coil, creating a magnetic field.
• Closing the Circuit
• The magnetic field pulls down a set of contacts (metal plates) inside the contactor.
• This closes the circuit between the high-voltage power supply and the heat pump components, such as the compressor or fan motor.
• The high-voltage electricity (e.g., 240 volts) flows through the closed contacts to power the connected devices.
• Maintaining Operation
• As long as the thermostat continues to send the control signal, the contactor remains energized, keeping the circuit closed and the system running.
• When the thermostat no longer demands heating or cooling, the control stops,  and the magnetic field deactivates.
• Opening the Circuit
• When the coil deactivates, a spring inside the contactor pushes the contacts apart.
• This breaks the circuit, stopping the flow of electricity to the heat pump's components, which shuts down the system.
• Key Features of the HPX1985 Contactor:
• Double Pole, Single Throw (DPST): This means it can switch two separate lines (poles) on or off simultaneously with a single throw (one operation). This is common in heat pump systems that require control of multiple electrical lines.
• Rated for 40 Amps: Can handle the high current drawn by compressors and motors.
• Coil Voltage: Operates on 24 volts for compatibility with most thermostat control system
