OEM Carrier 3-Pole Contactor 25A 115V (HN53CB115) for Model 09DK064500

This is the genuine OEM 3-pole contactor for the Carrier 09DK064500 commercial HVAC system. The contactor is the high-voltage switching relay that closes the circuit to energize the compressor and associated loads whenever the control board sends a 24V signal. When a contactor fails — due to pitted or welded contacts, a burned coil, or coil open-circuit — the system will either refuse to start entirely, run continuously without shutting off, or trip breakers repeatedly. Replacing with the correct OEM part restores factory switching performance and protects downstream compressor and motor components.

• Specs: 3-Pole | 25A FLA | 115V AC Coil | 240/480/600V Load Side | OEM Part# HN53CB115 | Direct replacement for HN53TB115 and HN52KC016
• OEM vs Generic: This factory-authorized Carrier contactor is manufactured to exact coil pull-in voltage, contact gap, and arc-suppression specifications. Off-brand contactors often use lower-grade silver-alloy contacts that pit faster under compressor inrush current, shortening service life.
• Install difficulty: 3/5 — Requires shutting off all power at the disconnect and verifying zero voltage with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring and label each wire before removal. Three-pole contactors carry higher load-side voltages — verify all terminals are torqued to spec after installation.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders ship same business day from our warehouse.

Compatibility: Designed for the Carrier 09DK064500 commercial packaged/condensing unit. Also cross-references HN53TB115 and HN52KC016. Always confirm coil voltage, pole count, and amperage rating against your unit's data plate and wiring diagram before ordering. Need help verifying fitment?
