Eaton BRH2100 Thermal Magnetic Circuit Breaker - UL 490
Part Number: BRH2100
Quick Summary
The Eaton BRH2100 Thermal Magnetic Circuit Breaker provides reliable overcurrent protection for BR load centers in residential panels. When amperage settings or mounting options don’t align with panel designs, field trips and downtime spike and maintenance costs rise. UL 490 certification and Federal Specifications W-C376 compliance ensure safety and reliability, while HACR-ready and 22 kAIC options support complex electrical loads. Integrated with Type BR Loadcenters and a 1-Inch plug-on mounting, it delivers faster installations and easier field upgrades, reducing total cost of ownership. With a 100 A rating and 120/240 V capability, it supports common residential and light commercial configurations. The common-trip design minimizes mismatched breakers in multi-circuit panels, improving fault visibility and simplifying compliance documentation.
