OEM Carrier 2-Pole Contactor 30 Amp 120V Coil — Model 09DE044100 (HN52KC052)

This OEM contactor is the factory-specified replacement for the Carrier model 09DE044100 and is sold under Carrier OEM part number HN52KC052. The contactor acts as the high-voltage relay that connects and disconnects power to the compressor and condenser fan motor each time your system cycles on and off. When this component fails, you may notice the system humming but not starting, chattering or buzzing sounds from the electrical panel, the unit failing to turn on at all, or — just as problematic — a system that won't shut off because the contacts have welded shut under excessive load.

• Specs: 2-Pole | 30 Amp (FLA) | 120V Coil | 50/60 Hz | Factory OEM tolerance — exact drop-in replacement for HN52KC052
• OEM vs Generic: OEM contactors are manufactured to Carrier's precise contact gap, coil pull-in voltage, and arc-quench specifications. Generic substitutes frequently use lower-grade silver-alloy contacts that pit and weld faster, shortening compressor life and risking stuck-on failures.
• Install difficulty: 2/5 — Always shut off power at the disconnect and verify zero voltage with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Coil wires and load wires must be transferred one at a time to avoid miswiring.
• Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for Carrier model 09DE044100. Verify your existing contactor's pole count (2-pole), amperage (30A), and coil voltage (120V) against your unit's data plate before ordering.
