OEM Carrier 1-Pole Contactor 30 Amp 24V for Model PY3GNAA30060AA (Part# HN51KC024)

This is the genuine OEM single-pole contactor factory-specified for the Carrier PY3GNAA30060AA packaged unit. The contactor is a high-voltage switching relay controlled by the 24V thermostat signal — it closes to send line voltage to the compressor and/or fan motor every time there is a call for cooling. When the contactor fails, contacts can pit, burn, or weld shut, leaving you with an AC system that won't start, short-cycles, or runs continuously without responding to the thermostat. Replacing a failed contactor promptly protects downstream components like the compressor from damage due to improper voltage delivery.

• Specs: 1-Pole configuration | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC coil voltage | 50/60 Hz | OEM Part# HN51KC024
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part built to exact factory tolerances. Generic contactors often use lower-grade contact materials prone to pitting and arcing, which can accelerate compressor wear and lead to premature re-failure.
• Install Difficulty: 2/5 — Shut off power at the disconnect box and wait for capacitors to discharge before touching any terminals. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph existing wiring before removing the old contactor. Verify 24V coil pull-in after installation with a thermostat call.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — get your system back online fast.
