Designed for real-world protection

The FD3100 provides fast, predictable interruption when overloads or short circuits occur, helping to prevent equipment damage and unplanned downtime. Its three-pole design ensures trip coordination across all phases, which is crucial for balanced three-phase motors and drives, minimizing the risk of damaging single-phase faults in a three-phase system.

Where it shines

• Distribution panels: protects feeders and branch circuits in commercial and industrial setups, supporting reliable power distribution.
• Motor control centers: safeguards three-phase motors and variable-frequency drives, aiding safe startup and controlled shutdown sequences.
• OEM equipment: compact, rugged protection integrated into machine control systems for factories and manufacturing lines.

What sets the FD3100 apart

• Coordinated trip across all three phases reduces the risk of phase-to-phase faults and improves overall system safety.
• Versatile voltage capability (600VAC / 250VDC) supports mixed electrical environments common in modern facilities.
• Three-pole construction provides robust protection for three-phase power distribution, motor circuits, and control panels in a single, compact unit.

Installation and practical considerations

When planning deployment, match the FD3100 to your panel design and bus arrangement for seamless integration. Ensure wiring adheres to your panel’s protection and conductor practices, and verify that the device is appropriate for the service conditions your facility requires. This breaker is built to contribute to safer operation and steady, reliable power protection in both new installations and retrofit projects.

Who benefits most

Industrial maintenance teams, OEM panel builders, and electrical engineers who design and service distribution panels, switchboards, and motor control centers will find the Eaton FD3100 an essential component for delivering predictable protection, reducing downtime, and extending equipment life in three-phase systems.
