OEM Carrier 2-Pole 30 Amp 120V Contactor HN52KC052 for Model 09DE146C600

This OEM contactor is the factory-specified replacement for the Carrier 09DE146C600. The contactor acts as a high-voltage relay, controlling the flow of electrical power to critical components such as the compressor and condenser fan motor. When energized by the 120V control coil, the contacts close and allow line voltage to reach the load. When the contactor fails, common symptoms include the unit failing to start, audible chattering or humming at the contactor, the system running continuously without shutting off, or visible burning and pitting on the contact tips.
