OEM Carrier 1-Pole Contactor 30 Amp 24V Coil — HN51KC024 for Model PH10JA03600GAGAA

This is the genuine OEM factory-authorized contactor for the Carrier PH10JA03600GAGAA packaged unit. The contactor is the high-voltage switching relay that closes when your thermostat sends a 24V call for cooling or heating, allowing line-voltage power to flow to the compressor and fan motor. When the contactor fails, symptoms include the system not responding to a thermostat call, the compressor not energizing, audible chattering or humming from the control box, or burned/pitted contact points that cause intermittent operation or total shutdown.

• 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 Factory Authorized Part is engineered to meet exact Carrier specifications, ensuring proper coil pull-in voltage, contact gap tolerance, and terminal fitment. Generic contactors may use undersized contact material that pits and welds prematurely under high-cycle summer loads.
• Install difficulty: 2/5 — Shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor. Verify 24V coil energization after installation with a thermostat call.
