OEM Carrier Single-Pole Contactor 1P 30A 24V — HN51KC024 for Model PH3ANA048000BAAA

This is the genuine OEM factory-specified contactor for the Carrier PH3ANA048000BAAA packaged unit. The contactor is the primary high-voltage switching relay in your HVAC system — when the 24V thermostat signal energizes the coil, the contactor closes and delivers line voltage to the compressor and/or fan motor. A failed contactor typically presents as an AC unit that won't turn on at all, hums without starting, or runs continuously without cycling off due to welded contacts.

• Specs: 1 Pole | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC Coil | 50/60 Hz | 240/277V Line Voltage | Normally Open | OEM Part # HN51KC024
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact coil resistance and contact material specifications. Generic contactors often use inferior contact alloys prone to pitting and arcing, shortening compressor life and risking nuisance lockouts.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph all wiring connections before disconnecting. Verify 24V coil pull-in after installation with a thermostat call for cooling.
