Eaton 140D316G11 1600A Circuit Breaker Current-Limiting

Meet the Eaton 140D316G11 1600A current-limiting circuit breaker — the robust guardian for high‑load electrical systems. Built to endure demanding industrial environments, this device delivers precise protection where it matters most, helping to safeguard feeders, switchgear, and connected equipment from disruptive faults.

As a current-limiting breaker, it acts quickly to interrupt fault currents and limit the energy that can reach downstream components. By curtailing fault energy, it reduces potential damage to conductors, transformers, and motors, while also contributing to safer maintenance and calmer arc‑flash scenarios. In essence, it helps keep downtime to a minimum and keeps critical processes online longer.

Why this breaker stands out

• High current rating: 1600 A capacity makes it well suited for main feeders and large-section power distribution paths in industrial settings.
• Current-limiting performance: quickly contains faults to minimize let-through energy, protecting downstream equipment and wiring.
• Rugged industrial build: designed to perform reliably in the vibration, temperature swings, and dust common in factories and data centers.
• Seamless compatibility: part of Eaton’s 140D family, designed to integrate with compatible panels, switchgear, and bus configurations when properly installed.

Ideal applications

Perfect for high‑amperage power delivery environments where protection and uptime matter. Use it as a main protective device in large distribution panels, critical feeders feeding heavy machinery, or within motor control centers where rapid interruption and energy limitation are essential to maintain process continuity.

What you gain with the 140D316G11

• Enhanced equipment protection through fast fault interruption and current limitation
• Reduced risk of secondary damage to cables, transformers, and motors
• Improved safety posture during fault conditions and maintenance
• Clear, model-specific part identification for streamlined replacements and upgrades
