FAQs
The BRHH240 is a Type BR 1-Inch plug-on circuit breaker designed for BR Loadcenters. It uses a plug-on mounting method, allowing quick installation without additional hardware. It is a two-pole device rated at 40 A, suitable for 120/240 V circuits, and fits standard BR panel frames for streamlined retrofits and new builds.
Key specs include 40 A amperage rating, 120/240 V voltage rating, two-pole design, and a 42 kAIC interrupt rating. It is UL 490 certified and compatible with common trip operation. The device accepts #14-4 AWG Cu/Al conductors and is intended for BR Loadcenters, offering reliable overcurrent protection in demanding applications.
Industrial control panels, commercial electrical distribution, and BR Loadcenter-based installations benefit most. The unit is well-suited for branch circuits requiring dependable protection, compact form factor, and easy field termination. It supports HACR and shunt-trip options, making it appropriate for spaces with regulated equipment cooling and safety interlocks.
The BRHH240 carries UL 490 certification and complies with Federal Specifications W-C376. It also supports HACR, shunt-trip, and high-magnetic settings as catalog notes indicate. These certifications ensure electrical safety, reliability, and compliance with applicable codes for residential, commercial, and light-industrial panels.
The BRHH240 is covered under Eaton’s warranty framework, including a limited lifetime residential and 1-year commercial warranty. This translates to lower life-cycle costs, predictable maintenance planning, and better total cost of ownership when deployed across panel upgrades and new builds in BR load center systems.
