BRHH2125 - 125 Amp Circuit Breaker

BRHH2125 - 125 Amp Circuit Breaker

The Eaton BRHH2125 is a 125 Amp two-pole circuit breaker designed for larger electrical loads that require dependable circuit protection and higher fault-current capability. Built for use in compatible Type BR loadcenters and panelboards, this breaker is commonly installed on 120/240VAC systems serving equipment such as HVAC units, electric water heaters, pumps, compressors, subpanels, and other high-demand applications.

One reason electricians often specify the BRHH2125 is its 42kAIC interrupting rating. In locations where available fault current levels are higher than what standard breakers are designed to handle, a higher interrupting capacity can be an important part of the electrical system. This makes the BRHH2125 a practical choice for many commercial facilities, service upgrades, and applications where additional fault protection is required.

The two-pole design protects both legs of a 240-volt circuit, while the HACR rating makes it suitable for heating, air-conditioning, and refrigeration equipment. Its plug-on mounting style allows for installation in compatible Type BR panels, helping simplify maintenance, breaker replacements, and panel upgrades.

Whether you're replacing an existing breaker or working on a new installation, the Eaton BRHH2125 is designed to provide the circuit protection needed for larger electrical loads while maintaining compatibility with existing Type BR equipment.
