OEM Carrier 2-Pole Contactor 30 Amp 24V Coil for Model PY1PEB048090NBAA (HN52KC025)

This OEM 2-pole contactor is the factory-specified replacement for the Carrier PY1PEB048090NBAA packaged unit. The contactor acts as the high-voltage switching relay that energizes both the compressor and condenser fan motor whenever the thermostat calls for cooling. A 24V control signal from the system board closes the contactor, allowing 240V line voltage to flow to the load. When the contactor fails — due to pitted contacts, coil burnout, or mechanical wear — the most common symptom is an AC unit that simply won't turn on, even though the thermostat is calling for cooling and the control board appears powered. You may also hear a loud buzzing or humming from the contactor coil as it attempts to pull in.

• Specs: 2-Pole (Double Pole) | 30 Amp FLA | 24V AC Coil | 50/60 Hz | 600V rated contacts | OEM Part # HN52KC025 (superseded by HN52KC024)
• OEM vs Generic: OEM contactors are built to Carrier's exact contact gap, coil pull-in voltage, and silver-alloy contact specifications. Generic contactors often use lower-grade contact alloys that pit and weld faster, especially under the high inrush current of scroll compressors — shortening compressor life and voiding equipment warranties.
• Install difficulty: 2/5 — Disconnect all power (line and control voltage) before replacing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wire connections before removal. Confirm coil voltage and pole count match your unit's data plate before installing.
• Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse.

Compatibility: Engineered to fit Carrier model PY1PEB048090NBAA packaged units. OEM part number HN52KC025 has been superseded by HN52KC024 — both are valid references for this application. Verify pole count (2-pole), amperage (30A), and coil voltage (24V) against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy.
