OEM Carrier 2-Pole Contactor 30 Amp 24V for Model PH1PEB042000AAAA

This OEM replacement contactor is the factory-specified high-voltage relay for the Carrier PH1PEB042000AAAA packaged unit. The contactor acts as the critical switch between your thermostat's 24V control signal and the high-voltage circuit powering the compressor and condenser fan. When your thermostat calls for cooling, the 24V coil energizes, closing the contacts and sending line voltage to the compressor. A failed contactor is one of the most common reasons an air conditioner won't turn on, hums without starting, or trips a breaker repeatedly.

• Specs: 2-Pole (Double Pole) | 30 Amp RES rating | 24V AC coil voltage | 50/60 Hz | Replaces OEM part number HN52KC025 (superseded by HN52KC024)
• OEM vs Generic: OEM contactors are manufactured to exact Carrier factory tolerances for contact gap, silver alloy content, and coil pull-in voltage. Generic alternatives often use lower-grade contact materials that pit and arc prematurely under residential load cycling, shortening compressor life.
• Install difficulty: 2/5 — Shut off power at both the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Discharge any capacitors in the cabinet before touching adjacent components.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered to fit Carrier model PH1PEB042000AAAA packaged units. Note that HN52KC025 has been officially superseded by Carrier part HN52KC024 — this listing ships the current OEM-approved replacement. Always verify pole count, amperage, and coil voltage against your unit's data plate before ordering. Have a fitment question? Our HVAC parts specialists verify compatibility before you buy.
