Eaton JGS3090FAG - 90 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Eaton JGS3090FAG is a 90A, 600V, 3-pole molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Its compact footprint helps maximize usable panel space, making it an ideal choice for both new installations and retrofits in commercial and light industrial settings.

Why the JGS3090FAG stands out

Compact molded-case design optimizes panel layout, freeing space for additional circuits without compromising protection. This makes it easier to fit into tight electrical rooms and crowded panels while maintaining clear labeling and organization.

Thermal-magnetic trip unit combines precise overload protection with fast magnetic response for short circuits. The result is stable, repeatable protection that minimizes nuisance trips and helps protect wiring and equipment during high-current events.

3-pole configuration supports three-phase circuits or multi-pole protection within a single device, simplifying installation in color-coded, organized panelboards and reducing the need for additional components.

600V rating expands its suitability to higher-voltage applications common in commercial and light industrial environments, providing robust protection across a wider range of equipment and loads.

OEM compatibility designed to pair with matching OEM loadcenters and panelboards, ensuring a reliable fit and coordinated performance within your existing electrical system.
