Carrier HN52KC024 Contactor

When you are handling service calls for Carrier, Bryant, or Payne units, the Carrier HN52KC024 Contactor is a standard-stock genuine OEM replacement essential for maintaining high-voltage line integrity. As a 2-pole contactor rated for 30 Amps, it provides full electrical isolation by switching both lines of a 240V circuit simultaneously. This design offers a significant upgrade in terms of safety and component protection compared to single-pole versions, as it ensures no residual voltage remains on the load side of the compressor or condenser fan motor when the 24V control signal is removed.

Built for the rigorous duty cycles of residential and light commercial HVAC systems, this Definite Purpose Contactor features a durable frame and high-quality internal contacts to prevent pitting and sticking. It is the direct factory-authorized replacement for several legacy part numbers, including HN51CB024 (converting from 1-pole to 2-pole), HN52HC030, and P282-1301. Integrating this OEM part ensures the system meets original manufacturer specifications for locked rotor amperage (LRA) and full load amperage (FLA) performance.

Key Benefits:

• Enhanced Safety Isolation: The 2-pole configuration breaks both legs of power, providing a safer environment for technicians during maintenance.
• OEM Compatibility: Specifically engineered for Carrier-family HVAC replacement parts, ensuring exact physical fit and electrical alignment.
• High-Inrush Durability: Rated for 30A FLA and up to 150A LRA (at 240V), managing the startup torque requirements of standard compressors.
• Reduced Arcing: High-performance contacts reduce electrical noise and wear, extending the life of the compressor start windings.
• Universal Coil Voltage: Standard 24VAC coil integrates seamlessly with most existing 50/60 Hz control boards and thermostats.

Common Questions:

Can I use this 2-pole HN52KC024 to replace a 1-pole HN51CB024?
Yes. This is the recommended direct replacement. Moving from a 1-pole to a 2-pole contactor provides more robust switching by isolating both power legs instead of just one, which is a common technical upgrade for older systems.

What are the terminal specifications?
This unit features standard 1/4-inch quick-connect terminals for the coil and heavy-duty box lugs/screws for the line and load connections, accommodating standard field wiring gauges.

Does this fit Bryant and Payne models as well?
Yes. Since Carrier, Bryant, and Payne share the same engineering platforms, the HN52KC024 is a cross-compatible OEM part for many models including the 581BTV series and outdoor condensers like the 38HD units.
