Feature → Business Impact → Application: 50 A rating at 120/240 V provides ample headroom for common branch circuits in commercial panels, enabling precise protection without over-specifying devices and reducing nuisance recalculation in layouts. Application: protects lighting and receptacle circuits in BR Loadcenters with predictable performance. Feature → Business Impact → Application: 42 kAIC interrupt rating delivers robust fault-current handling, minimizing equipment damage during short circuits and enhancing safety in panel assemblies. Application: suitable for panels in areas with higher fault currents, including light industrial environments. Feature → Business Impact → Application: Type BR 1-Inch plug-on mounting cuts install time and minimizes wiring errors, boosting field productivity. Application: rapid upgrades and replacements in existing BR installations. Feature → Business Impact → Application: Common breaker trip across multiple poles ensures coordinated protection, simplifying downstream device coordination and improving safety in multi-circuit panels. Application: essential in feeders and subpanels where synchronized tripping is required. Feature → Business Impact → Application: Wire size compatibility (#14-4 AWG Cu/Al) supports standard branch circuit wiring, reducing the need for adapters. Application: straightforward integration with typical 14 AWG conductors. Feature → Business Impact → Application: UL 490 and W-C376 compliance provide regulatory confidence, while the BR family’s HACR/shunt-trip options enable future-proofing; Warranty support reinforces ongoing maintenance planning. Application: regulatory-ready protection with scalable protection options for evolving control schemes.

FAQs
The BRHH150 is designed for Type BR Loadcenters in commercial and light-industrial panels. It uses a plug-on mounting, is a single-pole 50 A device rated for 120/240 V, and accepts #14-4 AWG Cu/Al conductors. It fits a compact 3x3x2 inch footprint and supports common-trip operation for coordinated protection in distributed circuits.
A 42 kAIC interrupt rating means the breaker can safely interrupt fault currents up to 42 kiloamperes, reducing potential damage to conductors and equipment during a short circuit. This rating enhances reliability in panels subject to higher inrush or fault currents and supports safer coordination with upstream protection.
HACR and shunt-trip options exist within selected amperage variants of the BR family. The BRHH150 carries the documented 50 A rating and catalog notes indicate HACR and high-magnetic settings are available for certain configurations. Verify the exact option set on the Eaton datasheet for this model to ensure compatibility with your control scheme.
The BRHH150 is UL 490 certified and complies with Federal Specifications W-C376, providing regulatory assurance for residential and commercial panel installations. This certification supports building code compliance and cross-industry acceptance for safe branch circuit protection in BR Loadcenters.
Due to its plug-on mounting and common-trip design, the BRHH150 reduces field labor and commissioning time while minimizing wiring errors. Its compatibility with Type BR Loadcenters simplifies retrofits, and UL/ Federal spec compliance reduces regulatory risk. The unit’s durable protection helps extend panel life and lowers total cost of ownership over time.
