BR370 - 70 Amp Circuit Breaker

BR370 - 70 Amp Circuit Breaker

The Eaton BR370 is a 70 Amp, three-pole thermal magnetic circuit breaker designed for use in compatible Eaton Type BR loadcenters. It provides protection against overloads and short circuits while allowing all three poles to trip together when a fault occurs. That common-trip operation is important in three-phase applications where disconnecting all conductors simultaneously helps protect equipment and maintain system safety.

With its plug-on design, the BR370 installs directly into Eaton BR panels, making it a practical choice for maintenance work, panel upgrades, and replacement projects.

You'll often find the BR370 protecting HVAC equipment, motors, distribution panels, subpanels, and other higher-demand electrical loads. Its ability to accept either copper or aluminum conductors adds installation flexibility, while the three-pole configuration makes it a dependable option wherever three-phase power is used.
