OEM Carrier 3-Pole Contactor 25A 115V for Model 09DK028100 (HN53CB115)

This is the genuine OEM Carrier contactor (part number HN53CB115), the factory-specified high-voltage switching relay for the Carrier 09DK028100 commercial HVAC unit. The contactor serves as the primary electrical switch that closes the high-voltage circuit to the compressor and/or fan motor when the thermostat or control board sends a 24V signal. When a contactor fails — due to burned or pitted contacts, a welded contactor, or a failed coil — the unit will either refuse to start, fail to respond to thermostat calls, or run continuously without cycling off. Replacing a worn contactor is one of the most cost-effective HVAC repairs available.

• Specs: 3-Pole configuration | 25 Amp FLA | 115V coil voltage | Heavy-duty definite-purpose design | Rated for commercial HVAC load applications
• OEM vs Generic: This genuine Carrier OEM contactor is manufactured to exact factory tolerances, ensuring proper coil pull-in voltage, contact gap, and arc suppression. Aftermarket contactors may vary in coil sensitivity and contact plating, shortening service life under heavy commercial cycling loads.
