Eaton BRH380 BR Thermal Magnetic Circuit Breaker - UL 490
Part Number: BRH380
Quick Summary
The Eaton BRH380 BR thermal magnetic circuit breaker protects three-phase circuits in industrial panels. When panel protection is required against short circuits and overloads, this common-trip unit minimizes nuisance trips and downtime. UL 490 certification and Federal Specifications W‑C376 compliance underpin its safety and federal-installation suitability, while HACR-ready and high-magnetic options extend its applicability to motors and demanding switching duties. Designed for Type BR Loadcenters, the plug-on 1-Inch package simplifies retrofits and spare parts management. With an 80 A rating, 22 kAIC interrupt capacity, and copper/aluminum wire compatibility (#4-1/0 AWG), it delivers reliable protection in industrial automation environments and supports compliant, efficient panel design.

Eaton Specification Sheet - BRH380
Eaton type BR circuit breaker limited warranty June 2024
Plug-on installation in BR Loadcenters reduces field wiring and speeds panel upgrades, cutting on-site labor time while delivering solid, secure connections to Cu/Al feeders. The common-trip, three-pole design ensures all phases disconnect together during faults, preventing backfeed and equipment damage in three-phase equipment like motors and conveyors. An 80 A rating paired with a 22 kAIC interrupt capacity provides strong short-circuit protection without overselecting devices, supporting longer equipment life and reduced downtime. The 240 V rating aligns with standard industrial distribution panels, enabling straightforward integration into existing electrical architectures. Cu/Al wire compatibility (#4-1/0 AWG) simplifies replacement projects and stock management. Certified to UL 490 with Federal Specifications W-C376 compliance, the BRH380 supports regulator-driven installations and high-reliability operation in harsh industrial environments, with options for switching duty, HACR, shunt trip, and high-magnetic settings to tailor protection to specific loads. In practice, these features translate to faster repairs, lower maintenance costs, and greater system uptime in automation facilities.
