OEM Carrier 3-Pole 75A 120V Contactor HN53HG120 for Model 07EB027431

This is the genuine OEM Carrier contactor (part number HN53HG120), the factory-specified replacement for the Carrier 07EB027431 commercial HVAC unit. The contactor is a heavy-duty, high-voltage switching relay that connects and disconnects line-voltage power to the compressor and fan motor loads on command from the 24V control circuit. On a 3-phase commercial system, a failed or welded contactor can mean the unit won't start at all, won't shut off, or trips repeatedly on overload — symptoms that demand an exact-spec replacement to protect compressor and motor life.

• Specs: 3-Pole configuration | 75A contact rating | 120V AC coil (50/60 Hz) | Replaces legacy part number HN53AG101 | Commercial-grade construction rated for demanding load cycles
• OEM vs Generic: OEM contactors are factory-matched to the exact coil voltage, pole configuration, and current rating required by the 07EB027431. Aftermarket contactors risk premature contact welding, coil burnout, and nuisance trips on high-inrush 3-phase loads — always use OEM on commercial equipment.
• Install difficulty: 3/5 — This is a 3-phase commercial contactor. Always shut off and lock out all power before servicing. Tools needed: screwdrivers (flathead and Phillips), torque screwdriver for terminal lugs, clamp meter to verify load. Photograph all wire terminations before removal. Recommend a licensed commercial HVAC technician for this repair.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
