OEM Carrier 3-Pole Contactor 40A 240V — HN53CD208 for Model 07EA022911

The Carrier HN53CD208 is the factory-specified OEM 3-pole contactor for the 07EA022911 packaged unit. This high-voltage relay is the critical switching component that closes the circuit to energize the compressor and condenser fan motor every time your thermostat calls for cooling. When the contactor fails — due to worn contacts, pitted surfaces, or a failed coil — the system will either refuse to start entirely, hum without engaging the compressor, or trip on high-pressure lockout. Replacing it with the correct OEM part restores factory-spec switching performance and protects your compressor from voltage drop and arcing damage.

• Specs: 3-Pole, Single-Throw | 40A FLA / 160–240A LRA | 208–240V 50/60Hz Coil | 240–600 VAC Rated | 4-Hole Mount | Cu 75°C Wire Terminals | 6 kAIC Interrupting Capacity at 240V
• OEM vs Generic: This OEM Carrier contactor is manufactured to exact factory tolerances for the 07EA022911. Generic 3-pole contactors often use silver-alloy contacts with higher resistance ratings, leading to arcing, pitting, and premature compressor failure under heavy load cycles.
• Install Difficulty: 3/5 — Requires disconnecting main power and verifying zero voltage with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, camera/phone to photograph existing wiring layout. Three-pole contactors carry more line connections than standard 2-pole units — label all wires before removal.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
