OEM Carrier 2-Pole Contactor 30 Amp 24V for Model PY1PPA042100ADBA — HN52KC025

This OEM-grade 2-pole condenser contactor is the factory-specified replacement for the Carrier PY1PPA042100ADBA packaged or split-system air conditioner. The contactor acts as the primary high-voltage relay in your outdoor unit — when the thermostat calls for cooling, a 24V control signal energizes the contactor coil, closing the high-voltage contacts that power the compressor and condenser fan motor. When this component fails, the unit either refuses to start entirely, hums without running, or trips the breaker repeatedly.

• Specs: 2-Pole (double pole) | 30 Amp RES / 20 Amp FLA | 24V AC coil | 50/60 Hz | Replaces OEM part number HN52KC025 (superseded by HN52KC024)
• OEM vs Generic: OEM-grade contactors use silver-alloy contact tips rated to factory tolerance, providing longer contact life and reduced arcing versus bargain aftermarket units that can pit and weld shut prematurely under compressor load.
• Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Photograph all wiring before disconnecting terminals. Swap one wire at a time to avoid miswiring.
• Warranty: 1-year OEM-grade replacement warranty. Ships same business day from our warehouse when ordered before 3PM local time.
