Eaton FDC2040 - 40 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Reliability and precise protection meet in the Eaton FDC2040—an essential 40A, 600V, 2-pole bolt-on molded case circuit breaker designed for demanding panelboards and load centers. Built to guard circuits against overcurrent and short-circuit events, it’s a robust solution for residential, commercial, and light industrial electrical systems.

• Secure bolt-on mounting creates a rigid, vibration-resistant bus connection, minimizing looseness and maintaining consistent electrical continuity in challenging environments.
• Thermal-magnetic trip unit delivers stable, repeatable protection: the thermal element responds to overloads while the magnetic element provides instantaneous interruption during short circuits, helping protect wiring and equipment.
• OEM-compatible design is built to work with matching Eaton OEM load centers and panelboards, ensuring straightforward installation and reliable performance within approved assemblies.
• Versatile, two-pole protection safeguards both conductors in a circuit, ensuring simultaneous disconnects to prevent backfeed and improve safety in multi-wire applications.
• Durable molded case construction combines compact form with rugged protection, suited for space-constrained panels without sacrificing reliability.
• Broad voltage reach with a 600V rating makes it suitable for a wide range of residential, commercial, and light industrial circuits, including general power and motor loads up to 40A.

The Eaton FDC2040 is purpose-built for dependable branch circuit protection in everyday panel installations. Ideal scenarios include upgrading aging panels, protecting lighting and receptacle circuits in small-to-mid size commercial spaces, and safeguarding light industrial feeders where consistent trip performance matters. Its bolt-on design, paired with a thermal-magnetic trip mechanism, provides a concrete, maintenance-friendly solution that you can trust to perform when it counts.
