OEM Carrier 3-Pole Contactor 40A 208/240V Coil — Model 07ED044911

The Carrier HN53CD208 is the factory-specified 3-pole contactor for Carrier model 07ED044911 commercial and packaged HVAC equipment. The contactor is the high-voltage relay that closes the power circuit to the compressor and load motors when the thermostat or control board sends a 24V signal. When contacts pit, burn, or weld shut, symptoms include the unit failing to start on a call for cooling, breakers tripping, or — in the case of welded contacts — the compressor running continuously and unable to shut off.

• Specs: 3-Pole | 40A FLA / 160–240A LRA | Coil Voltage: 208–220V/50Hz, 208–240V/60Hz | VAC Load Rating: 240–600V | Overload trip and push-to-trip feature | 4-hole panel mount
• OEM vs Generic: This is the genuine Carrier OEM contactor (HN53CD208), manufactured to exact factory coil pull-in voltage and contact gap tolerances. Generic contactors often use lighter-gauge contact alloys that pit faster under the high inrush current of 3-phase or large single-phase compressor loads.
• Install difficulty: 3/5 — Requires full system lockout/tagout (LOTO) before any work. Tools needed: flathead and Phillips screwdrivers, insulated needle-nose pliers, multimeter with AC voltage range. Always photograph all wiring and terminal labels before disconnecting. Verify coil voltage on the equipment data plate matches this part.
• Warranty: 1-year OEM factory warranty. In-stock — ships same business day from our warehouse when ordered before 3 PM local time.
