BR280 - 80 Amp Circuit Breaker

BR280 - 80 Amp Circuit Breaker

When your electrical system requires reliable protection for larger 240-volt circuits, the Eaton BR280 delivers the performance and dependability professionals expect from the Eaton Type BR product line. This 80 Amp, 2-pole circuit breaker is designed to safeguard electrical equipment and wiring from overloads and short circuits while providing the consistent operation needed for demanding residential and light commercial applications.

Whether you're powering a subpanel, HVAC system, electric water heater, air compressor, irrigation equipment, or other high-current loads, the BR280 helps keep your electrical distribution system protected and operating safely. Its thermal-magnetic trip mechanism responds to both prolonged overload conditions and sudden fault currents, while the common-trip design disconnects both poles simultaneously for added protection on 240-volt circuits.
