Eaton Specification Sheet - BRH280
Eaton type BR circuit breaker limited warranty June 2024
Feature: Thermal magnetic protection provides fast response to overcurrent conditions, with a 22 kAIC interrupt rating. Business impact: minimizes arc fault damage and reduces unplanned outages, lowering maintenance costs. Application: ideal for 80 A circuits feeding critical loads in BR load centers. Feature: Plug-on mounting for Type BR 1-Inch breakers enables quick field upgrades. Business impact: reduces installation time and labor costs, improving project ROI. Application: convenient retrofits in existing BR panels without reworking bus structures. Feature: Common trip two-pole design ensures simultaneous disconnection of both poles on multi-wire branch circuits. Business impact: enhances safety compliance and reduces shock risks during faults. Application: residential feeders and small commercial power distributions with shared neutrals. Feature: Large conductor compatibility with #4-1/0 AWG Cu/Al supports high-load feeders. Business impact: enables flexible wiring options and reduces the need for splices. Application: feeders to appliances, motors, and panel subfeeds. Feature: Comprehensive compliance footprint including UL 490 and Federal W-C376. Business impact: streamlines procurement and audit readiness while supporting HACR applications. Application: government, educational, and regulated facilities requiring verified standards. Feature: Compact footprint and lightweight design (3 in L x 2 in W x 3 in H; 0.6 lb). Business impact: frees panel space and simplifies shipping, handling, and field installation. Application: crowded or space-constrained electrical enclosures in retrofit or new builds.

FAQs
To install BRH280, ensure the panel accepts Type BR breakers, power is off, and the breaker is oriented to match the bus stabs. Insert the plug-on unit firmly into the BR load center bus, secure the conductor with #4-1/0 AWG Cu/Al as rated, and verify the common-trip linkage. Confirm panel labeling reflects 80 A rating and 120/240 V operation.
BRH280 is a two-pole 80 A breaker with a 22 kAIC interrupt rating for fast fault interruption at 120/240 V. It provides a common trip for multi-wire circuits, plug-on mounting for BR load centers, and compatibility with conductors #4-1/0 AWG Cu/Al. It carries UL 490 listing and supports HACR-rated applications.
Yes. BRH280 is designed for Type BR load centers, operating at 120/240 V with two poles and common-trip protection. Its compact 3x2x3 inch footprint and 0.6 lb weight make it ideal for space-constrained residential panels and small commercial distributions while maintaining robust short-circuit protection and compliance with applicable standards.
BRH280 carries UL 490 certification and complies with Federal Specifications W-C376. It is HACR-capable where applicable and is intended for use in BR load centers. These certifications aid procurement, safety audits, and regulatory compliance in both residential and light commercial installations.
BRH280’s common-trip, high interrupt rating and plug-on install reduce downtime and labor costs during installation or upgrades. The compact form factor saves panel space, while UL 490 and W-C376 compliance minimizes rework and compliance risk. Over time, these features contribute to lower maintenance overhead and faster project completion.
