The Carrier HH83XB460 is a high-performance 68-Amp 3-pole circuit breaker designed for demanding commercial HVACR applications. Engineered as the direct Carrier HH83XB469 replacement, this hydraulic-magnetic circuit breaker provides precise overcurrent protection and instantaneous trip response in 480V systems. Its three-pole configuration allows for synchronized interruption across multiple phases, ensuring electrical stability and preventing motor damage due to phase loss or single-phasing. With a robust 50/60 Hz compatibility, this 480V HVAC breaker is a staple in high-tonnage package units and industrial chillers.

Constructed within a compact 5.75" x 3" x 3" frame, the unit features high-torque screw terminals for secure, vibration-resistant wiring. This OEM Carrier electrical part is specifically rated for 68-79 amps, maintaining circuit protection integrity even in high-ambient temperature environments where thermal breakers often experience nuisance tripping. For contractors servicing older equipment, transitioning to the HH83XB460 ensures technical compliance with current Factory Authorized Parts standards without the need for mounting modifications.

• Precise Overcurrent Management: Maintains a 68A to 79A threshold, protecting critical 3-pole electrical path integrity in industrial motors.
• Hydraulic-Magnetic Action: Delivers consistent trip points regardless of ambient temperature, a critical factor for rooftop cabinet installations.
• Drop-in Compatibility: Serves as the official successor to the HH83XB469, utilizing identical mounting footprints for fast field swaps.
• Industrial Durability: Rated for 480 VAC operation, providing the necessary interrupting capacity for complex carrier cooling systems.

Common Questions

Is the HH83XB460 compatible with older units using the HH83XB469?
Yes, the HH83XB460 is the designated direct replacement for the discontinued HH83XB469, maintaining the same electrical ratings and physical dimensions for seamless integration.

What are the benefits of the hydraulic-magnetic trip mechanism in HVAC apps?
Unlike thermal breakers, hydraulic-magnetic units like this one are not sensitive to the high internal cabinet temperatures of HVAC systems, preventing nuisance trips on hot days.

Can this breaker be used in 50Hz and 60Hz systems?
Yes, it is rated for both 50Hz and 60Hz frequencies, making it versatile for a wide range of global Carrier equipment specifications.
