Why it matters for your panel

Designed to fit Type BR panels, including those from Eaton, Cutler-Hammer, and Westinghouse, this breaker can play a key role in protecting multi-wire branch circuits with mixed loads. The compact molded case helps maximize panel space while maintaining a robust protective function. The 90A rating is a common choice for higher-demand residential subcircuits, while the 120/240V operation aligns with typical split-phase layouts.

In real-world installations, the BR290 supports typical configurations—such as kitchen circuits, HVAC controls, lighting, and major appliance branches—where a reliable two-pole, 90A protection is appropriate. The 10 kAIC rating provides a comfortable safety margin against short-circuit events, helping panel designs meet standard protection requirements.

Installation and maintenance tips

• Verify panel compatibility with BR-series breakers before replacement
• Power down the main disconnect and test the circuit before removing or installing a breaker
• Follow manufacturer torque specs and panel guidelines to ensure a secure connection
