OEM Carrier 2-Pole Contactor 30 Amp 24V Coil — Model PY3PPA030040NA (HN52KC025)

This OEM-spec 2-pole condenser contactor is the factory-authorized replacement for the Carrier PY3PPA030040NA packaged unit, cross-referenced to OEM part number HN52KC025 (current supersede: HN52KC024). The contactor is the high-voltage relay that the thermostat's 24V control signal energizes to switch line-voltage power to the compressor and condenser fan motor. When it fails — due to pitted contacts, a burned coil, or welded-shut poles — the system will either refuse to start entirely, run continuously without shutting off, or trip the breaker repeatedly.

• Specs: 2-Pole (Double Pole) | 30 Amp RES rating | 24 VAC coil voltage | 50/60 Hz | Definite-purpose contactor | Factory-matched replacement for HN52KC025 / HN52KC024
• OEM vs Generic: OEM-spec contactors use silver-alloy contact tips rated for the exact load profile of your Carrier unit. Generic contactors often use lower-grade alloys that pit faster under compressor inrush current, leading to premature failure and potential compressor damage.
• Install difficulty: 2/5 — Always disconnect power at the breaker and verify zero voltage with a multimeter before touching any terminals. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. The contactor drops into the existing mounting bracket and reuses original wiring.
• Warranty: 1-year OEM-equivalent factory warranty. In stock and ships same business day from our warehouse.
