Eaton GBH3100 100A 3-Pole 600 V Circuit Breaker

The Eaton GBH3100 100A 3-Pole 600 V Circuit Breaker is built to protect three‑phase electrical systems with dependable trip performance and clear, immediate fault interruption. Designed to handle demanding industrial and commercial environments, this breaker combines solid construction with precise current protection to help keep equipment and wiring safe from overloads and short circuits.

• Current rating: 100 A — delivering reliable protection for rooms, machines, and panels that draw higher current
• Poles: 3 — optimized for 3‑phase power distribution, providing coordinated protection across all three live conductors
• Voltage rating: 600 V — suitable for medium‑voltage panel boards and equipment enclosures within standard industrial applications
• Part Number: GBH3100 — traceable specification for quick ordering and replacement in existing Eaton systems

Ideal for 3-phase circuits in manufacturing floors, HVAC equipment rooms, and utility‑class service panels, the GBH3100 delivers rapid interruption when fault conditions occur. Its 3‑pole configuration ensures that faults are cleared consistently across all phases, helping prevent damage to motors, drives, and other three‑phase loads.

Why this 3‑pole setup matters: in three‑phase systems, protecting all phases together reduces unbalanced loads and asymmetrical faults, which can lead to overheating and equipment failure. With the Eaton GBH3100, you gain straightforward protection for multi‑wire circuits without the need to juggle multiple single‑pole breakers.

Practical use scenarios include motor circuits, large compressor lines, industrial conveyors, and service disconnects where a single point of protection for three synchronized phases is essential. When selecting a breaker for your Eaton‑based infrastructure, the GBH3100 offers a precise match for 100 A three‑phase needs at up to 600 V, backed by Eaton’s reputation for dependable electrical protection.

Installation and handling tips: verify compatibility with your panel or enclosure, ensure conductors are sized for a 100 A rating, and follow local electrical codes for safe mounting and wiring. This breaker is designed to be a straightforward, drop‑in protection device for three‑phase systems requiring solid current limiting and rapid fault clearance.
