Description
The Carrier HN52KD024 is a Contactor 2-pole, 40-amp, electromechanical switch for HVAC equipment such as the air conditioner, heat pump, and furnace. Its current is 40A, the voltage of the coil is 24V AC, the frequency is 50/60 Hz, and the switching voltage is 600V AC. It works by making or breaking electronic circuits depending on the signals from a low-voltage control circuit. When energized, the coil of the contactor produces a magnetic field that operates the high-current contacts in making or breaking the circuit. It comprises the control and protection of high-power HVAC loads through the decoupling of control circuits from power circuits.
