90 A amperage rating provides robust protection for demanding feeder and branch circuits, reducing the risk of nuisance trips while allowing panel loads to peak without compromise. This translates into lower downtime and steadier process uptime in manufacturing and data-center environments. A 42 kAIC interrupt rating enables safe clearance of high fault currents, protecting personnel and critical equipment and improving overall system resilience in industrial panels. The Type BR 1-Inch plug-on mounting simplifies retrofits and new installs, saving installation time and reducing panel space requirements, which lowers labor costs and project schedules. Wire size compatibility to #4-1/0 AWG Cu/Al supports direct connections for large feeders, minimizing lugs and splices and aligning with NEC conductor sizing practices. The two-pole common-trip design ensures coordinated protection across circuits, while catalog notes indicate selectable options such as HACR, shunt trip, switching duty, and high magnetic settings for motor loads. Used with Type BR Loadcenters and UL 490 certified with W-C376 compliance, the BRHH290 fits regulatory requirements and procurement standards for a wide range of panel builds.
