Eaton HFD3100V Circuit Breaker, 100A, 3-Pole, 600V

The Eaton HFD3100V Circuit Breaker is built for demanding industrial electrical service, maintenance, and replacement projects. With a 3-pole design for three-phase protection and a 600V maximum system capacity, this unit delivers reliable interruption for demanding industrial loads. As part of Eaton’s AC DC series, the HFD3100V is designed to integrate smoothly with compatible panels, switchgear, and distribution equipment where dependable protection matters most.

Why this matters in the real world: industrial facilities rely on continuous uptime and safeguarding expensive motors, drives, and control circuitry. The HFD3100V provides precise, predictable protection for three-phase circuits, helping prevent damage from overloads and short circuits while supporting safer, easier maintenance and faster replacements when needed.

• 3-pole design for three-phase systems supports distribution networks that run on multi-phase power, simplifying integration into existing layouts.
• 100 A nominal rating aligns with common industrial service feeders and protection for moderate-to-high current circuits.
• 600V maximum system voltage enables use across a wide range of industrial applications, from manufacturing floors to data centers and beyond.
• AC DC series compatibility ensures the breaker aligns with Eaton’s ecosystem for consistency in performance and replacement parts.
• Part number clarity use HFD3100V to confirm fit and compatibility with your application requirements.
• Ideal for service, maintenance, and replacement projects—a trusted option when upgrading or sustaining existing Eaton installations.
