OEM Carrier 2-Pole Contactor 30 Amp 24V for Model PY1PEA048120AFBA — HN52KC025

This OEM contactor is the factory-specified high-voltage switching relay for the Carrier PY1PEA048120AFBA condenser unit. The contactor acts as the critical bridge between the 24V thermostat control signal and the 240V compressor and condenser fan circuit. When the thermostat calls for cooling, the 24V coil energizes the contactor, closing the high-voltage contacts to start the compressor. When the contactor fails — due to worn or pitted contacts, a burned coil, or contacts welded shut — the most common symptoms are an AC system that won't respond to a cooling call, a compressor that runs continuously without shutting off, or visible arcing and burning at the contact points inside the disconnect.

• Specs: 2-Pole (Double Pole) | 30 Amp RES rating | 20A FLA | 24 VAC coil voltage | 50/60 Hz | Tyco Electronics 3100A20Q328 series — factory-matched for Carrier PY1PEA048120AFBA
• OEM vs Generic: OEM contactors feature precision-machined silver-alloy contact tips engineered to the exact load cycles of your unit. Generic contactors frequently use lower-grade contact materials that pit and oxidize faster, leading to premature failure and potential compressor damage.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph all wiring connections before removing the old contactor. Discharge any residual voltage with a multimeter before touching terminals.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as the OEM replacement contactor for Carrier model PY1PEA048120AFBA. This 2-pole 30A 24V design is also used across a broad range of Carrier, Bryant, and Payne condenser and heat pump models — always verify pole count, amperage, and coil voltage against your unit's data plate before ordering. Our team is available to confirm fitment before you buy.
