OEM Carrier 3-Pole Contactor 25A 115V for Model 09DK074500 (HN53CB115)

This is the genuine OEM replacement contactor for the Carrier 09DK074500 commercial HVAC system. 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.

• Specs: 3-Pole | 25 Amp FLA | 35A Res | 115V AC Coil | 240/480/600V Load Voltage | OEM Part Number HN53CB115 | Cross-references: HN53TB115, HN52KC016, HN72AZ301
• OEM vs Generic: This is a genuine Carrier factory-authorized part (Hartland Controls HCCY3XT01DT103). OEM contactors use silver-alloy contact tips rated to full factory spec, unlike generic units that may use lower-grade alloys prone to pitting and early failure under compressor load.
• Install Difficulty: 3/5 — Requires full system lockout/tagout before servicing. Tools needed: multimeter, insulated screwdrivers, needle-nose pliers. Photograph all wire connections before removal. Verify coil voltage and pole count match before energizing. Commercial systems should be serviced by a licensed technician.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
