Carrier HH83XB428 Circuit Breaker

The Carrier HH83XB428 Circuit Breaker is a critical electrical protection component engineered specifically for high-demand HVACR applications. As a three-pole hydraulic-magnetic circuit breaker, it provides precise overcurrent and short-circuit protection for 600VAC three-phase systems. Designed for reliability in fluctuating thermal environments, this OEM Carrier replacement part utilizes a specialized fluid-core design that ensures consistent trip points regardless of ambient temperature changes. With a 12A current rating and screw terminal connections, it offers a secure, vibration-resistant interface suitable for commercial air conditioners, heat pumps, and chillers.

Replacing a compromised breaker with the genuine HH83XB428 maintains the original equipment's CSA listed safety standards and prevents nuisance tripping often associated with generic alternatives. The hydraulic-magnetic technology provides an inverse time delay for motor starting inrush currents while offering instantaneous protection during catastrophic electrical faults. For technicians servicing Carrier, Bryant, and Carlyle equipment, this component ensures the electrical integrity and operational uptime of the entire HVAC system.
