This OEM replacement contactor is the factory-specified part for the Carrier C50A205062 packaged unit. The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when the call for cooling comes in, the contactor closes its contacts to send 240V power to the compressor and condenser fan motor. When it fails, the system either won't turn on at all, hums without starting, or runs intermittently due to burned or pitted contact points. Replaces OEM part numbers HN53CB115, HN53CD115, and HN53HF122.
Compatibility: Designed for the Carrier C50A205062 commercial packaged unit. Cross-references OEM part numbers HN53CB115, HN53CD115, and HN53HF122. Verify coil voltage and amperage ratings on your unit's data plate before ordering. Our HVAC parts specialists are available to confirm fitment — contact us before you order if you have any questions.
