1) Feature: The 1-Inch plug-on design for Type BR load centers delivers streamlined mounting, accommodates retrofit projects, and minimizes panel space while preserving clearance for adjacent devices. Business impact: This compact footprint reduces installation labor, shortens commissioning cycles, and lowers total installed cost in new builds and service upgrades. Application: Ideal for residential and light commercial environments where fast, reliable protection and standardized BR components translate into faster project completion. 2) Feature: 70 A rating with 22 kAIC interrupt capability provides robust fault protection for branches and feeders in BR Loadcenters. Business impact: It tolerates higher short-circuit currents without nuisance trips, safeguarding connected equipment, reducing downtime, and improving system reliability. Application: Suitable for feeders and branch circuits in BR Loadcenters serving small motors, controls, and lighting circuits in commercial settings. 3) Feature: The device operates at 120/240 V with single-pole configuration, offering versatile compatibility across standard panels and service equipment. Business impact: By reducing the need for multiple breaker variants, it lowers SKU counts, simplifies procurement, and shortens lead times. Application: Commonly deployed in residential service entrances and light commercial distribution panels to provide compliant, space-efficient protection. 4) Feature: Wire size range #8-1/0 AWG Cu/Al enables direct termination of typical branch conductors with consistent torque and spacing. Business impact: Improved termination reliability reduces hot spots and arc risk, while speeding field wiring and inspection. Application: Especially beneficial in BR Loadcenter installations where copper-aluminum conductors are mixed or phased wiring is common. 5) Feature: Compliance with UL 490 and Federal Specifications W-C376 ensures adherence to recognized safety and performance benchmarks. Business impact: This simplifies supplier qualification, reduces audit findings, and accelerates approvals for panel builders and compliance teams. Application: Supports HACR, shunt-trip, and high-magnetic configurations as options within the BR family for enhanced protection. 6) Feature: BR Loadcenter compatibility and a 1-Inch plug-on format provide straightforward stocking and clear substitution paths. Business impact: Enables scalable protection across multiple panels, reduces SKU proliferation, and accelerates deployment for new builds and retrofits. Application: Ideal for panel builders and installers deploying modular BR Loadcenters in both retrofit and new-construction projects.
