OEM Carrier 2-Pole Contactor 30 Amp 24V for Model PY1PEB048130NBAA — Part# HN52KC025

This OEM contactor is the factory-specified high-voltage switching relay for the Carrier PY1PEB048130NBAA packaged unit. The contactor receives a low-voltage 24V signal from the thermostat or control board and closes its contacts to energize the compressor and condenser fan at 240V. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the system either won't start at all, hums with no compressor operation, or fails to shut off after the call for cooling ends.

• Specs: 2-Pole | 30 Amp (FLA 20A / RES 30A) | 24 VAC coil | 600V rated | Definite purpose contactor — factory-matched to OEM specifications
• OEM vs Generic: OEM contactors use silver-alloy contact tips rated for exact amperage draw. Generic units often use lower-grade contacts that pit and weld faster, especially under the high inrush current of a 4-ton compressor start cycle.
• Install difficulty: 2/5 — Shut off power at the disconnect and breaker before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Transfer wires one at a time to avoid miswiring.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.
