Eaton Specification Sheet - BRH125
Eaton type BR circuit breaker limited warranty June 2024
Paragraph 1: Feature: The 1-Inch plug-on design of the BRH125 keeps wiring straightforward and minimizes panel downtime by allowing quick replacement without removing the bus. Business Impact: this reduces labor time, lowers field error risk, and stabilizes maintenance schedules, improving overall equipment availability. Application: ideal for Type BR Loadcenters and 120/240 V distributions in light commercial and industrial panels.Paragraph 2: Feature: 25 A rating with a 22 kAIC interrupt capacity delivers robust fault clearance for motor starters and lighting circuits. Business Impact: higher fault tolerance translates to fewer nuisance trips under surge conditions and greater protection for connected equipment. Application: well-suited for BR Loadcenters in HVAC controls, manufacturing lines, and critical power feeds.Paragraph 3: Feature: UL 490 certification and Federal Specifications W-C376 compliance align with common regulatory requirements. Business Impact: supports faster procurement, easier audit trails, and proven performance in standardized environments. Application: commonly used in both new builds and retrofit projects across residential, commercial, and light industrial installations.Paragraph 4: Feature: Copper/Aluminum wire compatibility up to #14-4 AWG enables flexible terminations with widely used conductors. Business Impact: reduces rewiring needs, simplifies stocking, and accelerates field termination processes. Application: plug-on BRH125 installations across panelboards where Cu or Al conductors are used.Paragraph 5: Feature: Catalog notes indicate availability in switching duty, HACR, shunt-trip, and high magnetic variants. Business Impact: allows engineers to tailor protection to load profiles, improving safety margins and code compliance. Application: enables custom configurations for motors, HVAC, and other high-demand loads in BR Loadcenters.Paragraph 6: Feature: Industry-ready documentation and cross-reference data accompany BRH125, including wiring diagrams, catalog notes, and datasheets. Business Impact: reduces procurement lead times and minimizes mis-orders across teams. Application: supports field engineering, maintenance planning, and training programs.Paragraph 7: Feature: Global availability and consistent datasheet language aid international projects. Business Impact: simplifies multi-site deployments, minimizes translation errors, and aligns with global electrical standards. Application: ideal for multinational facilities and OEM integrations.
