EGH3100AFG | Circuit Breaker | 100A | 3-Pole | 347V

Introducing the EGH3100AFG industrial circuit breaker—a durable, three-pole protective device engineered for reliability in demanding power environments. With a 100A rating and 347V operating capability, it’s tailored for maintenance, retrofit, and replacement projects where matching specifications matters.

Key specifications

• Amperage: 100 A
• Poles: 3-Pole
• Voltage: 347 V
• Reference: Part number EGH3100AFG is the best compatibility reference

Why this circuit breaker stands out

Designed for environments where uptime and protective accuracy are non-negotiable, the EGH3100AFG provides robust protection for multi-phase feeders and motor circuits. Its 3-pole configuration supports three-phase systems, enabling balanced protection across all phases, reducing the risk of arc faults and overload damage. The 347V rating aligns with many commercial and industrial distribution schemes, making it a practical fit for retrofit and replacement in existing panels that use this voltage class.

Ideal use cases

• Retrofit projects where matching the original 3-phase, 347V setup is required
• Maintenance spares to minimize downtime during service outages
• New installations in facilities with 3-phase distribution at 347V
• Motor control centers and main distribution panels needing reliable overcurrent protection

Practical compatibility notes

Before ordering, confirm fit and ratings against your system requirements. The part number EGH3100AFG provides the most reliable reference for compatibility, ensuring the breaker will protect the intended circuits without compromising safety or performance.

If you’re upgrading an existing panel or panelboard, this 3-Pole, 100A, 347V circuit breaker is ready to slot into compatible enclosures and bus assemblies. It’s a practical choice for facilities aiming to standardize on a single protective device across multiple lines, simplifying maintenance and stocking.

Pro tips for installation and operation

• Verify conductor sizing and torque specs per local electrical codes and the panel manufacturer’s guidelines.
• Prepare for three-phase protection with proper wiring to each of the three poles to ensure balanced trip behavior across all phases.
• Keep a dedicated spare of the EGH3100AFG on hand for critical lines to minimize downtime during fault events.
