OEM Carrier Single-Pole Contactor 30A 24V Coil for Model PH10JA042000AAAA

This is the genuine OEM factory-specified contactor for the Carrier PH10JA042000AAAA. The contactor is the high-voltage switching relay that bridges line voltage to your compressor and fan motor every time the thermostat calls for cooling. When it fails, the system may refuse to start, hum without engaging, chatter loudly, or — just as dangerously — stay locked on even after the thermostat is satisfied. Burned or pitted contacts are the most common failure mode, especially in units that have logged several seasons of use.

• Specs: 1-Pole | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC coil voltage | 50/60 Hz | OEM Part# HN51KC024
• OEM vs Generic: OEM contactors are built to exact Carrier factory specifications with precision contact gap tolerances. Generic alternatives often use thinner contact material that accelerates pitting and shortens service life, especially under high-cycle summer loads.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before opening the electrical compartment. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph all wiring connections before removing the old contactor. Verify 24V coil pull-in after installation.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.
