OEM Carrier 2-Pole Contactor 30 Amp 24V for Model PY3PPA030040AB (HN52KC025)

This OEM 2-pole definite-purpose contactor is the factory-specified replacement for the Carrier PY3PPA030040AB condensing unit. The contactor acts as the high-voltage relay switch in your system — when the thermostat signals a cooling call, the 24V control circuit energizes the coil, closing the contacts and delivering 240V power to the compressor and condenser fan motor. When the contactor fails, you'll typically experience a system that won't turn on at all, hears audible chattering or humming at the outdoor unit, or short-cycles within seconds of startup. Burned or pitted contacts are the most common failure mode, often visible on inspection.

• Specs: 2-Pole | 30 Amp FLA | 24V AC Coil | 50/60 Hz | Definite purpose contactor | OEM Part # HN52KC025 (superseded by HN52KC024)
• OEM vs Generic: Genuine Carrier OEM contactors are manufactured to exact factory coil pull-in voltage and contact silver-alloy specifications. Generic contactors often use lower-grade contact materials that pit and weld faster under compressor inrush current loads, shortening service life significantly.
• Install Difficulty: 2/5 — Shut off power at the disconnect box and wait 5 minutes before opening the unit. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify coil voltage. Always photograph the existing wiring before removing any terminals.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered for Carrier model PY3PPA030040AB packaged or split-system condensing equipment. Note that OEM part # HN52KC025 has been superseded by HN52KC024 — this listing ships the current OEM replacement, which is a direct drop-in fit. Verify your unit's data plate amperage and coil voltage before ordering. Our team is available to confirm fitment before you buy.
