Eaton BAB3090HS - 90 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Engineered for dependable protection in modern electrical panels, the Eaton BAB3090HS is a 90A, 240V, 3-pole bolt-on molded case circuit breaker built to handle everyday overloads and faults with precision. Its secure bolt-on mounting delivers a rigid, low-impedance connection to the bus, reducing the risk of loosening from vibration or impact and enhancing overall panel reliability.

The thermal-magnetic trip unit provides stable, repeatable protection performance across a wide range of operating conditions. With fast fault interruption and predictable tripping behavior, this breaker helps safeguard branch circuits without unnecessary interruptions, even in environments with fluctuating loads.

Designed for seamless integration, the BAB3090HS is compatible with matching Eaton OEM loadcenters and panelboards, ensuring consistent fit, electrical characteristics, and trip settings across your Eaton-based distribution system. This makes maintenance and future panel upgrades simpler and more reliable.

Ideal for residential, commercial, and light industrial applications, this 3-pole breaker is well-suited for three-phase circuits and important protection where reliable power distribution matters—from office panelboards to small industrial control panels and service equipment feeding motors, compressors, and lights.
