OEM Carrier 3-Pole Contactor 60A 208-240V (HN53CD209 / HN53HF212) for Model ROA0550L2Y

This OEM 3-pole contactor is the factory-specified replacement for the Carrier ROA0550L2Y packaged or commercial HVAC unit. The contactor acts as the high-voltage switching relay that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24V control circuit signals the coil, the contactor closes, delivering line voltage to the load side. A failed contactor is one of the most common causes of a no-cooling call — symptoms include the unit not starting at all, audible chattering or humming at the contactor, pitted or burned contact points, or a system that runs continuously and won't shut off.

• Specs: 3-Pole | 60A Full Load Amps (FLA) | 208-240V Coil | 50/60 Hz | High-capacity definite-purpose design for commercial-grade HVAC loads
• OEM Part Numbers: HN53CD209 (primary) and HN53HF212 (active replacement). OEM contactors are wound to exact coil tolerances and use silver-alloy contacts rated for the full duty cycle of your Carrier system — generic substitutes often use lower-grade contact materials that pit prematurely under high inrush currents.
• Install difficulty: 3/5 — This is a 208-240V high-voltage component. Always shut off power at the disconnect and verify zero voltage with a multimeter before touching any wiring. Photograph all wiring before disconnection. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Licensed technician installation recommended for commercial units.
