Eaton BRH240 BR Thermal Magnetic Circuit Breaker - 22 kAIC
Part Number: BRH240
Quick Summary
BRH240 is a thermal magnetic circuit breaker for protecting two-pole circuits in Type BR Loadcenters. Engineers often face nuisance trips and mounting incompatibilities that slow installation. Certified to UL 490 and Federal Specifications W-C376, with a 22 kAIC interrupt rating, it delivers reliable fault protection in demanding panels. Designed for BR Loadcenters, it supports easy plug-on installation and compatibility with #14-4 AWG Cu/Al conductors, helping panel builders streamline procurement and maintenance while maintaining compliance and safety. It also benefits from common-trip operation, reducing the risk of uneven phase protection and simplifying troubleshooting for contractors and OEMs. That combination saves time and boosts overall panel reliability.
