Eaton FD2040 - 40 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Designed for dependable branch circuit protection in panelboards and load centers, the Eaton FD2040 is a 40A, 600V, 2-pole bolt-on molded case circuit breaker that keeps residential, commercial, and light industrial distributions safe and reliable.

Key advantages include a secure bolt-on mounting that delivers a rigid, vibration-resistant bus connection, minimizing movement that can lead to wear or nuisance trips. The integrated thermal-magnetic trip unit provides stable, repeatable protection across a range of temperatures and fault conditions, ensuring the circuit disconnects quickly during a short circuit while avoiding false trips on startup surges.

• 2-pole design ensures simultaneous disconnection of both conductors for safer shutdown.
• 40A, 600V rating supports typical branch circuits and modest industrial loads without over-sizing, while maintaining protection within spec.
• Bolt-on mounting compatible with matching OEM load centers and panelboards, enabling quick replacement or upgrades with minimal downtime.
• Molded case construction offers durability in everyday electrical environments, resisting impact and providing long service life.
• Application versatility suitable for residential, commercial, and light industrial electrical distributions, from lighting and receptacle circuits to small motor loads.

In practice, the FD2040 helps you maintain safe, orderly power distribution. When you need a backup or replacement for OEM panels, this unit's compatibility with matched Eaton equipment means fewer compatibility issues and smoother commissioning.
