FAQs
Yes. BRHH350 is a Type BR 1-Inch plug-on circuit breaker designed for BR Loadcenters. It mounts directly onto compatible buses and accepts #14-4 AWG Cu/Al conductors. During installation, align the breaker with the buses, firmly seat it, and tighten terminals to the manufacturer’s torque specs to ensure a solid, dependable connection.
BRHH350 provides a 42 kAIC interrupt rating with a common trip for the three poles. It is rated 50 A at 240 V, protecting multi-phase circuits and reducing the risk of simultaneous faults across poles. This configuration supports coordinated protection for motors and control panels with predictable, balanced trips.
Yes. The three-pole design with a common-trip feature makes BRHH350 well-suited for three-phase 240 V systems found in commercial and light-industrial environments. It delivers reliable protection for motors, HVAC equipment, and industrial controls within BR Loadcenters, helping prevent damage from short circuits and overloads.
BRHH350 carries UL 490 certification and meets Federal Specifications W-C376. These standards ensure safety, performance, and interchangeability in electrical distribution. The product’s documented warranty and compliance framework support regulatory audits and ongoing maintenance planning for multiple-panel installations.
BRHH350 is covered by a limited lifetime residential and one-year commercial warranty. Regular maintenance should focus on verifying torque at terminations, inspecting for signs of wear, and replacing components if trips or degraded contacts occur. This warranty framework helps reduce lifecycle risk and supports budget planning for panel upgrades.
