OEM Carrier 2-Pole Contactor 30 Amp 24V Coil for Model PY1PPB036060NBAA (HN52KC025)

This OEM Carrier contactor (part number HN52KC025) is the factory-specified high-voltage switching relay for the Carrier PY1PPB036060NBAA packaged unit. The contactor acts as the primary high-voltage switch in the condensing section: when the thermostat calls for cooling, the 24V control circuit energizes the contactor coil, closing the contacts and delivering line voltage to the compressor and condenser fan motor. When the contactor fails — due to burned or pitted contacts, a stuck plunger, or a failed coil — the system will hum without starting, fail to cool, or trip the breaker repeatedly.

• Specs: 2-Pole (Double Pole) | 30 Amp FLA | 24V AC coil | 50/60 Hz | Definite purpose contactor — factory-matched to Carrier PY1PPB036060NBAA specifications
• OEM vs Generic: Genuine OEM contactors use silver-alloy contacts rated to factory tolerances. Generic units often feature lower-grade contacts that pit and weld faster under load, especially during peak summer cycling.
• Install Difficulty: 3/5 — Disconnect power at the breaker AND the outdoor disconnect before opening the unit. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Verify coil voltage on your unit's data plate matches 24V before ordering.
• Warranty: 1-year OEM warranty. In-stock and ships same business day from our warehouse.
