Carrier HN51JD024 1-Pole 40Amp 24V Contactor

The Carrier HN51JD024 Contactor is a single-phase, single-pole device that works like an electronic switch in Carrier HVAC equipment It is a power relay that controls high electrical current of up to 40Amps in the equipment. A low voltage signal of 208-230 VAC turns on the contactor to effectively switch on or off high power loads such as compressor or heater. The contactor isolates the control circuit from the high-power circuit, thus protecting delicate electrical components from being damaged. Also, the contractor provides for efficient commutation of high currents, thus enhancing the reliability of the system.
