OEM Carrier Single-Pole Contactor 1-Pole 24V 30A for Model PH15NB04800GBBAA

This is the factory OEM replacement contactor for the Carrier PH15NB04800GBBAA heat pump system. The contactor is a high-voltage relay that receives a 24-volt signal from the thermostat and closes to energize the compressor and condenser fan motor. When a contactor fails, the system will either refuse to start entirely, short-cycle unexpectedly, or — in the case of welded contacts — run continuously without shutting off. Pitted, burned, or stuck contacts are among the most common causes of a no-cool or no-heat service call.

• Specs: 1-Pole (single-pole) | 24 VAC coil voltage | 30 amp FLA (Full Load Amps) | 150 amp LRA (Locked Rotor Amps) | 50/60 Hz | OEM Part# HN51KC024
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part engineered to exact specifications for the PH15NB04800GBBAA. OEM contactors maintain proper coil resistance and contact ratings — generic units with loose tolerances can weld shut or drop prematurely under high compressor load.
• Install difficulty: 2/5 — Always disconnect and lockout/tagout all power before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Verify 24V coil pull-in with a call from the thermostat after installation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
