Eaton type BR circuit breaker limited warranty June 2024
Type BR 1-Inch plug-on circuit breaker with two poles delivers a 45 A rating and 120/240 V operation, with a 22 kAIC interrupt capacity. This combination enables fast matching with BR Load Centers and reduces wiring errors in field installations. In real-world panel upgrades, plug-on mounting minimizes mis-wiring risk and speeds service replacements, a critical advantage when replacing aging breakers during tight schedules. The common breaker trip ensures simultaneous disconnection of both poles, protecting multi-wire branch circuits and motors and control circuits in panels. The 22 kAIC interrupt rating provides a wide fault-current margin, helping meet safety requirements while minimizing nuisance trips from transients. The unit wires with #14-4 AWG Cu/Al, supporting typical residential branch wiring and standard BR panels. Its compact 3 in depth, 3 in height, and 2 in width fit BR Load Centers while leaving space for feeders. UL 490 certification and Federal Specifications W-C376 support procurement and regulatory alignment, ensuring code compliance. The BRH245’s plug-on design reduces install time, while its 2-pole, common-trip configuration supports reliable motor protection and multi-wire circuit safety in both new builds and panel upgrades.

FAQs
Yes. The BRH245 is a Type BR 1-Inch plug-on circuit breaker designed to fit BR Load Centers. It mounts directly onto the bus with a plug-on method, simplifying replacement and reducing wiring errors. The two-pole design is suitable for common 120/240 V circuits and standard residential and light commercial panels.
The BRH245 offers a 45 A amperage rating, a 120/240 V operating range, and a 22 kAIC interrupt rating with a common-trip two-pole design. This combination supports reliable fault interruption for BR Load Centers, enabling selective coordination and compliance with UL 490 and W-C376 requirements.
Yes, for light commercial and residential motor control and general distribution. The two-pole protection and common-trip design help prevent back-fed faults across multi-wire circuits. For motor starters and feeders, ensure coordination with upstream devices and verify that the 22 kAIC rating matches system fault currents.
BRH245 is UL 490 certified and complies with Federal Specifications W-C376, supporting procurement for regulated and government projects. While CE or SIL certifications are not listed in the provided data, these existing certifications ensure safety, reliability, and code compliance in compliant markets.
Routine inspections and torque checks of terminals are recommended, along with periodic trip-function verification. The plug-on design reduces labor for replacements, lowering maintenance costs. Coupled with UL 490 certification and warranty provisions, customers gain from minimized downtime and extended service life, translating to lower total cost of ownership.
