Eaton JD3090 - 90 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton JD3090 is a 90A, 600V, three-pole bolt-on molded case circuit breaker engineered to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Its secure bolt-on mounting creates a rigid, vibration-resistant bus connection that stays tight even in demanding installations, helping you avoid intermittent connections and nuisance trips.

Why this breaker stands out

• Secure bolt-on mounting provides a robust, vibration-resistant connection to the panel bus, reducing the risk of loosening over time and making installation steady and reliable.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining a thermal element for prolonged overcurrent with a magnetic element that instantly reacts to short circuits.
• Three-pole design protects all conductors in three-phase systems, ensuring coordinated protection across each phase where required.
• 90A, 600V rating matches mid-sized branch circuits found in residential, commercial, and light industrial environments, providing appropriate protection without overkill.
• OEM compatibility is designed to work with matching OEM load centers and panelboards, simplifying replacements and upgrades without compatibility hitches.

Ideal use cases

• Upgrading or replacing breakers in existing panelboards and load centers that require a bolt-on, high-reliability solution.
• Residential service upgrades, commercial lighting and outlet circuits, or light industrial feeders where steady protection and solid bus connections are critical.
• New installations where a durable, three-pole breaker helps protect three-phase circuits with precise trip characteristics.

Practical benefits you’ll notice

• Reduced trip nuisance due to the dependable thermal-magnetic trip characteristics, keeping systems more consistently powered.
• Quicker, more predictable maintenance and replacement thanks to clear compatibility with OEM hardware.
• Clear protection for essential loads in panelboards and load centers, supporting safer, more reliable electrical distribution.
