Eaton EGB3025AFG 3025A 3-Pole 347 V Circuit Breaker

Engineered for robust protection in commercial and industrial electrical systems, the Eaton EGB3025AFG is a 3-Pole 347 V circuit breaker designed to guard three-phase feeders against overloads and faults. With a current rating of 3025 A, this unit is purpose-built for mid-voltage distribution where reliability matters most and precise protection across all phases is essential.

Why this breaker stands out:

Key features

• Part number: EGB3025AFG
• Current rating: 3025 A
• Poles: 3 (three-pole design for synchronized 3-phase protection)
• Voltage rating: 347 V (suitable for 3-phase, low- to medium-voltage applications)
• Type: Three-phase circuit breaker designed to interrupt faults across all phases, reducing the risk of phase imbalance and equipment damage

What problems it solves

In three-phase systems, a fault on one phase can quickly cascade into equipment damage and unplanned downtime. The Eaton EGB3025AFG provides reliable, coordinated interruption across all three conductors, helping protect motors, compressors, pumps, and other essential loads from overloads and short circuits. Its 347 V rating positions it well for commercial and industrial distribution networks where three-phase power is standard, delivering dependable protection without unnecessary tripping in normal operating conditions.

Ideal for

electricians and facilities managers working with Eaton-compatible panels and mid-voltage distribution setups in offices, manufacturing floors, data centers, and large HVAC or processing facilities. If your system operates on three-phase 347 V service and requires a single device to guard all phases, this breaker aligns with your protection strategy and procurement workflow.

Practical use cases

• Protecting 3-phase motors (compressors, fans, pumps) in commercial buildings and industrial equipment
• Guarding three-phase distribution feeders in data centers and manufacturing lines
• Integrating into Eaton-based panel networks where a dedicated 3-pole, 347 V breaker is required

Tips for installation and selection

When choosing this breaker, verify that the panel and bus configuration support a 3-pole design and that the system voltage aligns with the 347 V rating. Confirm the current rating matches the protected load and that the Eaton EGB family is the correct lineage for your distribution equipment. For service reliability, pair this breaker with proper wiring, torque specifications, and adherence to electrical codes and safety guidelines during installation.
