E3100 | Circuit Breaker | 100A | 3-Pole | 240V

Introducing the E3100 Industrial Circuit Breaker — a purpose-built protection device for demanding 3-phase electrical systems. When maintenance, retrofit, or replacement is on the agenda, this 100A, 3-pole 240V breaker delivers reliable, predictable protection and seamless compatibility with legacy equipment.

Key specifications

• Amperage: 100A
• Poles: 3-Pole
• Voltage: 240V

Compatibility and reference

For best results, confirm fit and ratings before ordering. The part number E3100 is the most reliable reference for compatibility with your panel, bus, and enclosure. Always match your system's specifications to the breaker's ratings to ensure proper protection.

Why choose the E3100?

Unlike generic substitutes, this E3100 is purpose-built to align with industrial 3-phase 240V circuits, delivering 100A of protection for main feeders, motor circuits, and other demanding loads. Its 3-pole design ensures simultaneous interruption across all phases, simplifying panel wiring and improving safety in equipment rooms, manufacturing lines, and service panels.

Ideal use cases

• Maintenance: replace worn or non-matching breakers to restore original protection levels
• Retrofit: upgrade or modernize existing 3-phase systems without changing panel infrastructure
• Replacement: maintain continuity of 3-phase 240V circuits in industrial equipment

Installation and best practices

Work with a qualified electrician to verify compatibility and safely install the E3100. Before any work, power down the panel and verify that the new breaker matches the panel's mounting type and electrical ratings. Keep a record of the part number for future maintenance and ordering consistency.
