OEM Carrier 3-Pole Contactor 40A 208/240V — HN53CD208 for Model 07EB027931

This OEM Carrier contactor (part number HN53CD208) is the factory-specified replacement for the Carrier 07EB027931 commercial HVAC unit. The contactor is the high-voltage switching relay that energizes the compressor and condenser fan circuit on a call for cooling. When the contactor fails — due to worn contacts, welded poles, or a burned coil — the system will either fail to start entirely, run continuously without shutting off, or trip on high-pressure lockout. This OEM part restores factory-correct switching performance.

• Specs: 3-Pole | 40A FLA | 160–240A LRA | Coil Voltage: 208–220V/50Hz & 208–240V/60Hz | VAC Rating: 240–600V | 4-hole mount | Part No. HN53CD208
• OEM vs Generic: OEM contactors use factory-spec copper-alloy contacts rated to exact pole geometry and coil impedance. Generic replacements often use inferior contact materials that arc and pit faster, shortening service life — especially critical in 3-pole commercial applications.
• Install difficulty: 3/5 — Always disconnect and lock out power before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, camera or phone to photograph wiring before removal. Coil voltage must match the control circuit. Professional installation strongly recommended for commercial units.
• Warranty: 1-year OEM factory warranty. In-stock — ships same business day from our warehouse.

Compatibility: Designed for Carrier model 07EB027931 commercial HVAC equipment. Verify pole count, FLA rating, and coil voltage on your unit's nameplate before ordering. Our HVAC parts specialists are available to confirm fitment — contact us before you order if you have any questions.
