Eaton GDB3035 35A 3-Pole 480 V Circuit Breaker

Eaton GDB3035 is a 35 A, 3‑pole circuit breaker designed for 480 V three‑phase electrical systems. This part (GDB3035) delivers reliable overcurrent protection where power distribution runs across three simultaneous phases, helping safeguard motors, drives, and feeders from overloads and short circuits.

With its 3‑pole configuration, the GDB3035 ensures that all three phases disconnect together during a fault, maintaining system balance and reducing the risk of phase-to-phase damage. Rated for 480 V, it aligns with typical industrial and commercial power distributions, making it a practical choice for facilities that run equipment on higher voltage tiered electrical floors.

Why this breaker is ideal for your 480 V, three‑phase needs

Designed for industrial environments, the Eaton GDB3035 provides dependable protection for three‑phase feeders and motors operating at 480 V. Its 35 A rating is well suited for circuits where motors, drives, or distribution feeders draw moderate to higher starting currents, ensuring prompt disconnection when fault conditions occur without nuisance trips under normal operation.

Use cases include protecting three‑phase motor circuits, 480 V feeders in manufacturing lines, and distribution segments within larger commercial or industrial facilities. By coordinating protection across all phases, this breaker helps maintain equipment longevity and reduces downtime caused by electrical faults.

Practical considerations and installation ideas

• Verify that your panel or disconnect enclosure supports three‑pole 480 V protection and that the GDB3035 is the correct fit for your distribution scheme.
• Before servicing, follow standard safety procedures for de‑energizing and locking out the circuit; ensure all power is isolated prior to wiring or replacement.
• Consult relevant electrical codes and manufacturer guidelines to confirm compatibility with your existing Eaton protection lineup and to determine proper torque specifications for termination.

Choose the Eaton GDB3035 when you need a dependable, purpose‑built solution for protecting 3‑phase, 480 V circuits with a 35 A protection level. Its alignment with Eaton’s robust distribution framework helps you maintain consistent performance across your facility’s power infrastructure.
