OEM Carrier Single-Pole Contactor 30A 24V Coil — HN51KC024 for Model PY4GNAB42060NA

This is the genuine OEM factory-replacement contactor for the Carrier PY4GNAB42060NA packaged unit. The contactor is the high-voltage relay that closes the compressor and condenser fan motor circuit every time your thermostat calls for cooling or heating. When the 24V control signal energizes the coil, the contacts snap closed and power flows to the load. A failed contactor is one of the most common no-cool service calls: pitted or welded contacts, a burned coil, or a chattering relay that won't pull in are the top symptoms. Replacing it with the correct OEM part restores factory-spec performance and prevents premature compressor wear.

• Specs: 1-Pole configuration | 24 VAC coil voltage | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 50/60 Hz | OEM Part # HN51KC024
• OEM vs Generic: This is the Factory Authorized Part built to exact Carrier corporation specifications. Generic contactors often use lighter-gauge contact material rated for fewer switching cycles, leading to earlier pitting, coil failure, and nuisance lockouts under high summer loads.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Verify 24V coil pull-in after installation with a thermostat call before buttoning up the panel.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
