OEM Carrier 1-Pole Contactor 30 Amp 24V Coil (HN51KC024) for Model PH10JA03600GAHAA

This is the genuine OEM factory-replacement contactor for the Carrier PH10JA03600GAHAA packaged unit. The contactor is the high-voltage relay that receives the 24V thermostat call and closes the power circuit to your compressor and/or condenser fan motor. When a contactor fails, symptoms typically include the outdoor unit not energizing at all, the system humming without starting, or the compressor running continuously because pitted contacts have welded shut. Replacing a worn or failed contactor is one of the most common and cost-effective HVAC repairs available.

• Specs: 1-Pole | 30 Amp FLA / 150 Amp LRA | 24 VAC Coil | 50/60 Hz | 240V line voltage | Normally-open, single-throw definite-purpose design
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part (part# HN51KC024), built to exact OEM contact material and coil resistance specifications.
