This OEM replacement contactor is the factory-specified part for the Carrier C4850C50Z3060200 packaged unit. The contactor acts as the high-voltage relay that closes the circuit to power the compressor and condenser fan when the thermostat calls for cooling. A failed contactor is one of the most common reasons a packaged unit hums but won't start, trips the breaker repeatedly, or simply shows no response when cooling is demanded. Replaces OEM part numbers HN53CB115 and HN53HF122.
Compatibility: Engineered as a direct OEM replacement for Carrier model C4850C50Z3060200 packaged units. Cross-references OEM part numbers HN53CB115 and HN53HF122. Always verify coil voltage and pole configuration on your unit's data plate before ordering. Our fitment team is available to confirm compatibility — just reach out before you buy.
