OEM Carrier 3-Pole Contactor 25A 115V (HN53CB115) for Model 09DK054600

This is the genuine OEM 3-pole contactor for the Carrier 09DK054600 commercial HVAC unit. The contactor is the high-voltage switching relay that energizes the compressor and condenser fan motors every time your thermostat calls for cooling or heating. When the contactor fails — through pitted contacts, a burned coil, or a stuck plunger — the unit will fail to start, hum without engaging, or run continuously without cycling off. Replacing it with the correct OEM part (HN53CB115) restores precise switching performance and protects downstream components from voltage irregularities caused by a degraded generic substitute.

• Specs: 3-Pole | 25A FLA | 115V coil voltage | Direct OEM replacement for Carrier 09DK054600 | Also supersedes HN53TB115 and HN52KC016
• OEM vs Generic: OEM contactors meet Carrier's exact coil pull-in voltage and contact gap tolerances. Off-brand units frequently use thinner contact material, leading to accelerated pitting under high-cycle commercial loads and premature compressor failure.
• Install difficulty: 3/5 — Shut off all power at the disconnect and verify zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, wire labels. Always photograph all wiring before disconnecting terminals. A 3-pole contactor has more terminals than a standard 2-pole — take your time.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for Carrier model 09DK054600. Verify pole count, amperage, and coil voltage against your unit's data plate before ordering. Also supersedes legacy part numbers HN53TB115 and HN52KC016. Need help confirming fitment? Our HVAC parts specialists are standing by — order with confidence.
