OEM Carrier 3-Pole Contactor 24V 60 FLA for Model TCHC2550HECMRLP501

This factory-authorized OEM contactor is the direct replacement for Carrier model TCHC2550HECMRLP501 commercial packaged HVAC equipment. The contactor is the high-voltage switching relay that responds to the 24V control signal from the system board, closing its poles to deliver line voltage to the compressor and associated loads. When a contactor fails — due to pitted or welded contacts, a burned coil, or mechanical wear — the unit will either refuse to start entirely, run continuously without shutting off, or trip on a safety lockout. Replacing this OEM part restores precise factory switching performance and protects downstream compressor components from voltage irregularities.

• Specs: 3-Pole | 24V 50/60Hz Coil | 60 FLA (Full Load Amps) | 75 Amp RES | Factory-matched to Carrier tolerances | OEM Part Numbers: HN53TZ024 (primary), HN52TC040 (alternate)
• OEM vs Generic: OEM contactors are manufactured to Carrier's exact coil pull-in voltage and contact gap specifications. Generic contactors often use lower-grade contact alloys that pit faster under the high-inrush loads of commercial compressors, leading to premature failure and potential compressor damage.
• Install difficulty: 3/5 — Requires lockout/tagout of all power (line and control voltage) before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (verify coil continuity and contact resistance). Photograph all wiring connections before removing the old contactor. This is a 3-pole unit — confirm pole count and FLA rating on the equipment data plate before installation.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered for Carrier model TCHC2550HECMRLP501 commercial packaged units. Also fits select 50HECMRLP-500, 50HECMRLP-501, and 50HECMRAH-100 series equipment. Always verify pole count, FLA rating, and coil voltage against your unit's data plate before ordering. Our team is available to confirm fitment — contact us before you order if you have any questions.
