Feature: Plug-on mounting enables quick, tool-friendly installation and reduces wiring errors. Business Impact: Speeds panel upgrades and lowers installation labor. Application: Ideal for Type BR Loadcenters in new builds and retrofits. Feature: Common breaker trip provides coordinated protection across connected circuits. Business Impact: Enhances safety and simplifies coordination with other protective devices. Application: Suitable for multi-pole BR configurations in commercial panels. Feature: 55 A amperage rating and 42 kAIC interrupt capacity. Business Impact: Robust short-circuit protection with narrow fault-current tolerance. Application: Fits typical industrial feeders while meeting short-circuit requirements. Feature: 120/240 V operation for split-phase systems. Business Impact: Versatile deployment across residential-commercial panels without adapters. Application: BR Loadcenters and mixed-voltage distribution. Feature: Cu/Al wire size compatibility (#14-3/0 AWG). Business Impact: Broad wiring compatibility reduces inventory needs and installation complexity. Application: Field terminations in standard conduit and lugs. Feature: UL 490 listing and Federal Specifications W-C376 compliance plus optional HACR/shunt-trip/high-magnetic settings. Business Impact: Regulatory alignment and expanded protection options minimize compliance risk. Application: Commercial and industrial installations requiring code-approved protection.

FAQs
The BRHH155 is designed for Type BR Loadcenters and uses a plug-on mounting method, enabling quick upgrades and consistent protection across standard BR panels.
The BRHH155 has a 55 A amperage rating and a 120/240 V operating voltage, suitable for split-phase residential and light commercial circuits.
BRHH155 is UL 490 listed and complies with Federal Specifications Classification W-C376; it also supports options like HACR, shunt-trip, and high-magnetic settings for broader protection needs.
Install via plug-on mounting in BR Loadcenters, terminate with #14-3/0 AWG Cu/Al conductors, and ensure the unit is part of a common-trip configuration where applicable to achieve coordinated protection.
A 42 kAIC interrupt rating indicates strong short-circuit interrupt capability, reducing the risk of excessive fault current and enhancing panel protection in high-current scenarios.
