Eaton FDB3110 - 110 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton FDB3110 is a robust three-pole, 110 A, 600 V bolt-on molded case circuit breaker engineered to guard your power distribution with precision. Built for reliable branch circuit overcurrent and short-circuit protection, it’s a trustworthy choice for panelboards and loadcenters in demanding electrical environments.

Why this breaker stands out

• Secure bolt-on mounting ensures a rigid, vibration-resistant bus connection. In environments with equipment vibration or shifting panels, this design minimizes connection looseness and maintains consistent protection performance over time.
• Thermal-magnetic trip unit delivers stable, repeatable protection. The thermal element handles overloads predictably, while the magnetic element responds rapidly to dangerous short circuits, helping to prevent damage to downstream equipment.
• 3-pole configuration provides balanced protection for three-phase systems, simplifying installation in commercial and light industrial applications where 3-phase power is common.
• 600 V / 110 A rating makes it suitable for a wide range of panelboard and loadcenter applications, offering reliable protection for feeders, motors, and branch circuits in both commercial and light industrial settings.
• OEM-compatible compatibility works seamlessly with matching OEM loadcenters and panelboards, enabling straightforward replacements and upgrades without reconfiguring downstream wiring.

Ideal use cases and practical scenarios

Designed for residential, commercial, and light industrial applications, the FDB3110 is a solid fit for:

• Three-phase feeder protection in commercial panelboards and distribution centers
• Motor control circuits and service feeders in light industrial facilities
• Upgrading or replacing aging or damaged breakers to restore reliable protection
• Systems where vibration or movement is a factor, thanks to its secure bolt-on mounting

How it helps you manage risk and downtime

With a precise trip characteristic, the FDB3110 helps you prevent nuisance trips during normal load fluctuations while still delivering rapid isolation during faults. This means less unexplained outages, shorter downtime, and a safer electrical installation for occupants and equipment.
