Carrier HH83XB425 Circuit Breaker

The Carrier HH83XB425 Circuit Breaker is a critical industrial-grade 600V 3-pole circuit breaker designed for high-voltage HVACR applications. Engineered as a hydraulic-magnetic circuit breaker, this component provides precise overcurrent protection for Carrier, Bryant, and Payne commercial equipment. It features a 77-amp full load amperage (FLA) rating and is capable of handling a 240-amp locked rotor amperage (LRA), making it an essential replacement for ensuring system stability under heavy startup loads. Professional technicians should note that the HH83XB425 is identical to HH83XB425B, offering the same 3-phase electrical safety and trip characteristics (89-amp trip point) required for large-scale inducer motors and blower assemblies.

Utilizing genuine Carrier OEM parts like this 77 amp 3 pole breaker ensures exact mechanical and electrical fitment, reducing the risk of nuisance tripping or premature component failure. The unit is built with robust screw terminals for secure HVAC circuit protection and is rated for 50/60 Hz operation. This Carlyle circuit breaker serves as a direct replacement in models such as the 48AYD030 and 50P9 series, maintaining the high-voltage integrity of your commercial rooftop or chiller units.
