OEM Carrier 1-Pole Contactor 24V 30 Amp (HN51KC024) for Model PH13NR04200GAKAA

This OEM single-pole contactor is the factory-specified replacement for the Carrier PH13NR04200GAKAA heat pump system. The contactor acts as the primary high-voltage relay in the condensing unit, closing the power circuit to the compressor and condenser fan motor every time the thermostat sends a 24V call for cooling. When the contactor fails, symptoms range from an outdoor unit that won't energize at all, to chattering or humming sounds, to a unit that runs continuously due to welded contact points — all of which demand immediate replacement to avoid compressor damage.

• Specs: 1-Pole | 24 VAC coil voltage | 30 Amp FLA (Full Load Amps) | 150 Amp LRA (Locked Rotor Amps) | 50/60 Hz | OEM Part# HN51KC024
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, built to exact factory tolerances. Generic contactors may use thinner contact material that pits and welds prematurely, risking compressor failure — the most expensive repair on any system.
• Install difficulty: 2/5 — Shut off power at the disconnect and breaker before opening the unit. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Photograph all wiring before disconnecting — low-voltage coil leads and line/load terminals must be reconnected correctly. Verify contactor pull-in with a 24V thermostat call after installation.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
