This OEM contactor (part number HN52KC025) is the factory-specified high-voltage switching relay for the Carrier PY2PEB060130AA packaged unit. The contactor acts as the primary electrical switch that connects line voltage to the compressor and condenser fan motor when the thermostat calls for cooling. A failed contactor is one of the most common causes of a system that runs constantly, won't turn on at all, or drops out mid-cycle — often accompanied by visible pitting or burning on the contact points.
Compatibility: Designed as a direct OEM replacement for the Carrier PY2PEB060130AA packaged unit. Always verify coil voltage and pole configuration on your unit's data plate before ordering. Our HVAC parts specialists are available to confirm fitment prior to purchase — order with confidence.
