OEM Carrier 2-Pole Contactor 30 Amp 24V (HN52KC025) for Model PY2PEB042090AB

This is the factory-specified OEM 2-pole contactor for the Carrier PY2PEB042090AB packaged unit. The contactor is the high-voltage relay that receives a low-voltage signal (24V) from the thermostat and closes the circuit to deliver line voltage to the compressor and condenser fan motor. When the contactor fails, the most common symptoms are an air conditioner that won't turn on at all, a unit that hums but never starts, or a unit that runs continuously and won't shut off — all signs of welded or pitted contact points.

• Specs: 2-Pole | 30 Amp FLA | 24V AC Coil | 50/60 Hz | Definite Purpose Contactor | OEM Part # HN52KC025 (superseded by HN52KC024)
• OEM vs Generic: OEM contactors use factory-grade silver-alloy contact points with tight coil pull-in voltage tolerances. Generic contactors often use inferior contact alloys that pit and weld faster, causing premature compressor failure or dangerous lock-on conditions.
• Install difficulty: 2/5 — Shut off power at the disconnect and verify zero voltage with a multimeter before touching any terminals. Photograph all wiring before disconnecting. Tools needed: flathead screwdriver, needle-nose pliers, multimeter. Label each wire to its terminal before removal.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Factory-matched for Carrier model PY2PEB042090AB packaged gas/electric units. Note that OEM part HN52KC025 has been superseded by HN52KC024 — both are fully interchangeable direct replacements. Confirm coil voltage (24V) and pole count (2-pole) on your unit's data plate before ordering. Our fitment team is available to verify compatibility before you buy.
