OEM Carrier Contactor 2-Pole 24V Coil for Model PY3PEA042060NA — HN52KC025

This is the genuine OEM replacement contactor for the Carrier PY3PEA042060NA packaged unit, carrying Carrier part number HN52KC025. The contactor is a high-voltage relay that acts as the primary switching device in your system's electrical circuit — when the thermostat calls for cooling, the 24V control board energizes the contactor coil, closing the high-voltage contacts that power the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioning system fails to respond: symptoms include the outdoor unit not turning on, the compressor humming but not starting, contacts that are visibly burned or pitted, or the system running continuously without shutting off.

• Specs: 2-Pole design | 24V AC coil voltage | High-amperage load contacts rated for compressor duty | Direct OEM factory replacement for part number HN52KC025
• OEM vs Generic: This genuine Carrier OEM contactor is manufactured to exact factory specifications, including contact gap, silver-alloy contact material, and coil pull-in voltage. Generic contactors often use lower-grade contact alloys that arc and pit faster, dramatically shortening service life in high-cycle residential applications.
• Install difficulty: 3/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before beginning work. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all high-voltage wiring connections before removing the old contactor to ensure correct reinstallation.
• Warranty: Backed by Carrier's OEM factory warranty. Orders placed by cutoff ship same business day from our NationalHVACParts.com warehouse.

Compatibility: Engineered as the factory-specified contactor for the Carrier PY3PEA042060NA packaged unit.
