OEM Carrier 2-Pole Contactor 35A 208/240V for Model 09DE146C230

This OEM replacement contactor (part# HN52KC053) is the factory-specified high-voltage relay for the Carrier 09DE146C230. The contactor acts as the primary power switch for your condensing unit — when the thermostat calls for cooling, the 24V control circuit energizes the coil, closing the contacts and delivering 208/240V power to the compressor and condenser fan motor. When a contactor fails, the result is typically an AC unit that hums but won't start, trips the breaker, or simply has no response at all when cooling is demanded.

• Specs: 2-Pole | 35 Amps | 208/240V load voltage | 24V coil | Dimensions: 1.8"L × 3.1"W × 2.2"H | Weight: 0.35 lbs
• OEM vs Generic: This is a genuine Carrier OEM contactor, built to exact factory contact gap, coil pull-in voltage, and contact plating specifications. Generic contactors often use thinner silver-alloy contacts that pit and weld prematurely under high cycling loads, leading to repeat failures.
• Install difficulty: 2/5 — Always disconnect power at both the outdoor disconnect and the breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and insulated gloves. Photograph all wiring connections before removing the old contactor to ensure correct reinstallation.
• Warranty: Backed by Carrier's OEM factory warranty. In-stock and ships same business day from our warehouse.
