Allen-Bradley 140G-G6C3-C20 circuit breaker is a reliable three-pole protective device engineered for 3‑phase electrical systems. With its 3‑Pole configuration, it provides synchronized protection across all phases, helping prevent equipment damage and unplanned downtime in industrial environments.

This unit is ideal for maintenance, retrofit, and replacement projects where exact specifications matter. When upgrading panels or replacing an aging breaker, matching the exact part number (140G-G6C3-C20) ensures compatibility of frame, terminals, and trip characteristics, so you can avoid surprises in your control enclosure.

Key differentiators

• Exact compatibility via part number: The 140G-G6C3-C20 is the best reference for fit and ratings, reducing guesswork during procurement.
• Three-phase protection: 3-pole design aligns with standard 3-phase power distribution in manufacturing lines and process control rooms.
• Targeted use cases: maintenance, retrofits, and replacements where you need to preserve protective characteristics and wiring layout.
• Fit-first approach: Confirm the unit's fit and ratings prior to ordering to ensure seamless installation.

Practical considerations for installation and lifecycle

• Inspect for any physical damage during removal or transport and verify the line-side and load-side terminal configurations match your panel requirements.
• Cross-check panel documentation to ensure the breaker frame and trip settings align with your system protection strategy.
• Keep the original part number handy for future replacements or quick reordering, minimizing downtime in maintenance windows.

Whether you're refreshing a legacy control panel, performing a targeted retrofit, or replacing a failed protective device, the Allen-Bradley 140G-G6C3-C20 3-Pole circuit breaker offers predictable performance and straightforward compatibility—backed by the precision you expect from Allen-Bradley.
