Eaton EGB2040FFB - 40 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Engineered for dependable branch circuit protection, the Eaton EGB2040FFB is a 40A, 480V, 2-pole bolt-on molded case circuit breaker designed for panelboards and loadcenters. Its rugged bolt-on mounting delivers a rigid, vibration-resistant connection that stays secure in demanding environments, while its thermal-magnetic trip unit provides reliable protection for both overloads and short circuits.

• Secure bolt-on mounting creates a stable bus connection that resists looseness from vibration and panel movement.
• Thermal-magnetic trip combines time-delay overload sensing with instantaneous magnetic tripping for high-fault protection, reducing nuisance trips and safeguarding critical circuits.
• OEM compatibility works with matching Eaton OEM loadcenters and panelboards, simplifying replacements and ensuring coordinated protection.
• Versatile 480V performance designed for residential, commercial, and light industrial applications where 480V branch circuits are common.
• 2-pole, 40A coverage protects both conductors in the circuit, ideal for feeding equipment and panels in higher voltage installations.

Practical use cases include upgrading aging panels in small commercial spaces, adding reliable protection to HVAC equipment feeders, or replacing failed breakers in light industrial control panels. Because it's a bolt-on molded case design, installation can be straightforward in compatible panelboxes, with a snug fit that minimizes bus-bar movement.

What to expect in daily operation

The EGB2040FFB delivers predictable performance. In steady-state operation, the thermal element monitors current and ambient temperature to prevent nuisance trips, while the magnetic element responds instantly to short circuits, helping minimize damage and downtime.

Installation and compatibility tips

• Confirm your panelboard type supports bolt-on molded-case breakers and that a 40A, 2-pole device is suitable for your 480V supply.
• Inspect the bus connection and tighten mounting hardware to manufacturer recommendations before energizing.
• Use with compatible Eaton OEM load centers and panelboards to maximize protection coordination and reliability.

Choose Eaton EGB2040FFB when you need robust, OEM-compatible protection that stands up to vibration and the demands of 480V systems. AmpState is your source for reliable replacements that keep panelboards and loadcenters performing at their best.
