Overview
The Eaton BR280 is a Type BR 1-inch plug-on circuit breaker engineered for residential and commercial electrical distribution systems. Built to handle heavy residential loads, the Eaton BR280 is an 80A, 2-pole miniature circuit breaker that delivers dependable thermal-magnetic protection for demanding circuits, including subpanels and HVAC equipment requiring an HACR-rated device. It provides reliable protection by interrupting electrical flow during overloads or short circuits, ensuring safety and preventing damage to your electrical system.

- Plug-on design ensures a secure installation into standard Eaton Type BR panelboards
- Quick-make, quick-break switch mechanism combined with inverse time element tripping operation and trip-free handle design
- Handle position provides visual trip position
- HCAR application listing
- Common trip operation (both poles trip simultaneously on fault)
