Carrier HN53CB115 3-Pole Contactor 25 Amp Coil 120V

The Carrier HN53CB115 is a 3-pole Contactor, an electronically operated switch used in various equipment such as air conditioning systems, heat pump systems, and furnaces. Electromechanical relays operate by making or breaking electrical circuits in response to the control signal. When energized, the coil of the contactor produces a magnetic field that changes the internal contacts and enables a high current to circulate between the compressor and other electrical parts. When de-energized, the contactor opens the circuit, interrupting the current and so protecting the compressor. It involves the safe and efficient operation of HVAC systems, compressor life is also conserved they do not start and stop frequently, and power management.
