OEM Carrier 3-Pole Contactor 208/240V 60 Amp for Model RSA0550L2Y

This OEM Carrier 3-pole compressor contactor is the factory-specified replacement for the Carrier RSA0550L2Y rooftop and commercial HVAC unit. The contactor serves as the high-current switching relay in your system: when the thermostat or control board sends a low-voltage (208/240V coil) signal, the contactor closes, routing line voltage to the compressor and condenser fan motor. When the contactor fails — through burned contacts, a welded coil, or pitted contact surfaces — you'll typically see the system fail to start, hear audible chattering or humming from the electrical compartment, or experience a compressor that runs continuously even after a shutoff call. OEM part numbers HN53CD209 and HN53HF212 are both genuine Carrier Factory Authorized Parts for this application.

• Specs: 3-Pole | 208/240V coil voltage | 60A Full Load Amps (FLA) | 50/60 Hz | Screw terminal connections | Weight approx. 1.45 lbs | Dimensions: 2.5"L × 4.2"W × 3.6"H
• OEM vs Generic: OEM contactors are manufactured to exact Carrier tolerances for contact gap, coil pull-in voltage, and arc suppression rating. Aftermarket contactors often run undersized contact plating, accelerating pitting and shortening compressor life — especially critical at the 60A load rating of this unit.
• Install difficulty: 3/5 — This is a high-amperage commercial-grade contactor. Always disconnect and lockout/tagout all power before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" and 5/16" nut drivers, multimeter (test coil continuity and verify 0V at load terminals before touching). Photograph all wire connections before removal. Professional installation recommended.
• Warranty: 1-year OEM factory warranty. In-stock — ships same business day from our warehouse.

Compatibility: Designed for Carrier model RSA0550L2Y commercial rooftop units. OEM part numbers HN53CD209 and HN53HF212 are cross-referenced applications for this platform. Always verify coil voltage and amperage on your unit's data plate before ordering. Need fitment confirmation? Our HVAC parts specialists verify compatibility before every order — call or chat today.
