The contactor is a heavy-duty, high-voltage relay that controls the flow of power to the compressor and associated loads. When the 24V control signal energizes the 115V coil, the contactor closes its poles and delivers line voltage to the compressor circuit. A failed contactor typically presents as a system that won't start, trips on lockout immediately after a call for cooling, or shows burned\/pitted contact surfaces upon inspection. Replacing with the correct OEM part ensures factory-matched electrical performance and longevity.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 3-Pole | 25 Amp FLA | 35A Res | 115V AC Coil | 240\/480\/600V Load Voltage | OEM Part Number HN53CB115 | Cross-references: HN53TB115, HN52KC016, HN72AZ301\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory-authorized part (Hartland Controls HCCY3XT01DT103).
