Eaton FD2090 90 A 600 V 2-Pole Circuit Breaker

The Eaton FD2090 is a purpose-built 90 A, 600 V, 2-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers. Built for installers who demand a secure, enduring connection, this unit combines precise thermal-magnetic tripping with robust mechanical design to keep electrical systems protected and uninterrupted.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that stays tight through routing, installation, and routine equipment movement—reducing the risk of loose connections and intermittent faults.
• Thermal-magnetic trip unit delivers stable, repeatable protection by accurately responding to both sustained overloads and short-circuit faults, minimizing nuisance trips while safeguarding downstream circuitry.
• OEM-compatible construction is designed to pair with matching Eaton load centers and panelboards, ensuring straightforward installation and reliable electrical coordination within existing systems.

Where it shines—the FD2090 is ideal for residential setups that require solid burden protection, commercial environments with regular equipment start-ups, and light industrial installations where vibration reliability and long-term performance matter. Use cases include panelboard upgrades, circuit additions, and retrofit projects where a like-for-like, bolt-on breaker's characteristics are essential for system safety and code compliance.

• Branch circuit overcurrent and short-circuit protection for critical feeders and distribution circuits.
• Suitable for panels and load centers designed for bolt-on molded case breakers across residential, commercial, and light industrial applications.
• The bolt-on design and rugged construction stand up to vibration and routine mechanical stress better than some alternative mounting styles.
