Carrier HH83XB486 Circuit Breaker

For industrial HVACR applications requiring reliable overcurrent protection, the Carrier HH83XB486 Circuit Breaker is a critical OEM replacement part designed for high-voltage single-phase systems. This single-pole circuit breaker features a 7.4 Amp rating and is engineered to operate efficiently at 480 VAC within 50/60 Hz frequencies. Built with a robust hydraulic-magnetic trip mechanism, it provides precise interruption during electrical faults, protecting expensive compressors and motors from terminal damage. The compact 3-inch by 5.7-inch frame includes lug terminal connections, ensuring a secure, vibration-resistant interface common in demanding Carrier and Bryant rooftop units. As a factory authorized part, the HH83XB486 guarantees exact mechanical fitment and matches the original trip curves required for system safety and HVAC electrical protection. For technicians service-identifying this component, it serves as a direct drop-in for part number HH83XB486A, maintaining the electrical integrity and UL/CSA listing compliance of the original equipment during field repairs.

• Precise Overload Protection: Utilizes hydraulic-magnetic technology to provide stable trip points unaffected by ambient temperature fluctuations in outdoor enclosures.
• High Voltage Compatibility: Specifically rated for 480V HVAC systems, making it ideal for commercial single-phase power distribution.
• Secure Lug Terminals: Designed with heavy-duty lug-style connectors for reliable high-amperage wire termination.
• Genuine OEM Fit: Ensures seamless integration with Carrier and Bryant control panels without the need for mounting modifications.

• Is the HH83XB486 compatible with 3-phase systems? No, this is a single-pole breaker designed specifically for single-phase circuits up to 480 VAC.
• What does the 7.4 Amp rating signify? This represents the maximum continuous current the breaker can handle before the overcurrent protection mechanism initiates a trip.
• Is this a direct replacement for HH83XB486A? Yes, the Carrier HH83XB486 is the current authorized replacement for the older "A" suffix version.
