OEM Carrier Single-Pole Contactor 30A 24V Coil for Model PH13NR04200GAAAA

This OEM Carrier contactor (part# HN51KC024) is the factory-specified high-voltage switching relay for the Carrier PH13NR04200GAAAA heat pump condensing unit. The contactor acts as the primary power bridge between the 24V thermostat control circuit and the high-voltage compressor and condenser fan motor loads. When the thermostat calls for cooling or heating, the 24V coil energizes and pulls the contact plunger down, completing the high-voltage circuit to start the system. A failed contactor typically presents as an AC or heat pump that won't turn on at all, a unit that chatters or hums without starting, or — if contacts weld shut — a system that runs continuously and won't shut off.

• Specs: 1-Pole configuration | 30A Full Load Amps (FLA) / 150A Locked Rotor Amps (LRA) | 24 VAC coil voltage | 50/60 Hz | Factory OEM part number HN51KC024
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part built to exact OEM contact gap, spring tension, and coil resistance specifications. Generic contactors often use lower-grade contact alloys that pit faster under compressor load cycling, reducing service life significantly.
• Install Difficulty: 2/5 — Shut off all power at the disconnect and breaker before touching any wiring. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Always photograph all wire connections before removal. Swap wires one at a time to avoid miswiring the 24V coil leads.
• Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.
