Carrier HN52KA001 Contactor

The Carrier HN52KA001 Contactor is a high-performance, industrial-grade solution designed for HVACR motor control and switching tasks. This 2-pole contactor is engineered to handle a 40 amp resistive load and is equipped with a 480V coil (rated for 380-415V/480V at 50/60Hz), making it essential for heavy-duty commercial condensers and air handling units. Its robust construction ensures reliable circuit isolation and switching, even in demanding environments that require high Locked Rotor Amps (LRA) and Full Load Amps (FLA) tolerance. When performing a field replacement, this OEM Carrier part provides the exact fit and electrical specifications required to maintain system integrity and prevent premature component failure in multi-phase industrial equipment.

• High Amperage Capacity: Rated for a 40A current rating per pole to support powerful compressor and motor start-ups.
• Industrial-Grade Coil: Optimized for 480V applications, ensuring consistent magnetic engagement and reduced contact chatter.
• Compact 2-Pole Design: Streamlined footprint allows for efficient installation in crowded electrical control panels.
• Broad Compatibility: A standard replacement for various Carrier, Bryant, and Payne commercial HVAC systems.

What is the coil voltage rating for the HN52KA001?
This contactor features a specialized 480V coil, typically rated for 380-415 VAC at 50Hz and 480 VAC at 60Hz. Always verify your control circuit voltage before installation to avoid coil burnout.

Can this 2-pole contactor replace a single-pole version?
While it can physically break two lines of power, you must ensure the amperage and coil voltage align with the original manufacturer specifications. Using a 40A contactor where a higher rating is required will lead to pitted contacts.

Does this part include the mounting hardware?
The HN52KA001 is typically supplied as the contactor unit itself. Technicians should retain existing mounting screws or use standard self-tapping screws compatible with the control box backplane.
