BRH390 - 90 Amp Circuit Breaker

BRH390 - 90 Amp Circuit Breaker

The BRH390 is a 90 Amp, 3-pole plug-on circuit breaker designed for use in three-phase electrical systems. Rated for 22kAIC at 240VAC, it provides protection against overloads and short circuits in applications where higher fault-current interruption is required.

Its plug-on design allows for straightforward installation in compatible panelboards, making it a practical choice for your panel upgrades, replacement projects, and new electrical installations. The 3-pole configuration is commonly used for motors, HVAC equipment, refrigeration systems, pumps, compressors, and other three-phase loads found in commercial and industrial facilities.

The breaker is also HACR rated, making it suitable for heating, air conditioning, and refrigeration applications. Whether you're installing it in a warehouse, manufacturing plant, office building, retail facility, or mechanical room, the BRH390 is built for everyday electrical distribution applications where dependable circuit protection is needed.

With a compact footprint and a 90 Amp rating, the BRH390 is a good fit for electrical systems that require higher-capacity three-phase protection while making efficient use of available panel space.
