Eaton type BR circuit breaker limited warranty June 2024
Type BR 1-Inch plug-on circuit breaker design enables quick, tool-free installation in BR loadcenters. This reduces commissioning time and minimizes wiring errors, delivering faster protection for control panels. Ideal for both new builds and retrofit projects in residential and light commercial distributions. Amperage rating of 50 A and a 240 V voltage rating provide dependable branch-circuit protection for standard commercial loads. The fixed ratings simplify selection and ensure consistent performance across equipment and wiring, reducing over- or under-protective scenarios. Interruption rating of 22 kAIC offers robust fault-current protection in medium-to-high fault environments, supporting safer operation in facilities with higher bus fault levels. This improves coordination with upstream devices. Common breaker trip (BR) ensures all poles disconnect together on a fault, enhancing safety and reducing arc-flash risk. Conductor compatibility with #14-4 AWG Cu/Al streamlines wiring and procurement in typical panel builds. UL 490 certification and Federal Specifications W-C376 compliance provide regulatory assurance for electrical distributions. Catalog notes cover 10-150 A ranges, switching duty, HACR, shunt trip and high-magnetic settings, expanding application options. Plug-on mounting simplifies retrofits and new installations by minimizing hardware requirements and ensuring a secure fit within BR loadcenters.

FAQs
BRH350 is designed for Type BR Loadcenters and uses a 1-Inch plug-on mounting. It fits BR-series panels, enabling streamlined retrofits and new installations without additional adapter kits or special hardware.
Key specs include 50 A amperage rating, 240 V voltage rating, 22 kAIC interrupt capacity, and three-pole arrangement with common-trip operation. It uses #14-4 AWG Cu/Al conductors and is intended for BR loadcenter applications.
Common trip ensures all poles trip together when a fault occurs, reducing the risk of partial trips and improving coordination across multi-pole circuits. This enhances safety, simplifies maintenance, and lowers arc-flash exposure during faults.
Yes, BRH350 carries UL 490 certification and complies with Federal Specifications W-C376. This confirms adherence to recognized safety standards for low-voltage circuit breakers and aligns with regulatory requirements for electrical installations.
Use the plug-on mounting with BR loadcenters for a secure, quick install. Ensure wires are within #14-4 AWG Cu/Al range, respect the 3-pole configuration, and select appropriate switching duty and HACR options per the catalog notes to optimize protection and lifecycle.
