Eaton ST304G - 400A, 600V, 3-Phase Copper Standard Plug-In Busway | AmpState

The Eaton ST304G copper standard plug-in busway straight section is engineered for robust, high-demand industrial power distribution. With a 400 A rating and a 600 V capacity, this 3‑phase, 3‑wire busway delivers reliable, scalable power to busy facilities while keeping installation streamlined and flexible.

• Copper conductor for superior conductivity and long-term reliability in demanding environments, delivering efficient power delivery with reduced energy loss.
• 400 A continuous rating and 600 V capability to support heavy machinery, production lines, and large equipment banks.
• 3‑phase, 3‑wire configuration with 50% ground bus designed to provide effective grounding while maintaining a compact, modular layout.
• Plug-in design enables quick assembly, simple future expansion, and easier maintenance compared to traditional hard-wired layouts.
• Straight-section geometry for straightforward, linear power runs along manufacturing floors, switchgear corridors, or equipment banks, with scalable integration into existing busway networks.
• Industrial-grade construction built to withstand the wear and tear of continuous operation in factories, data centers, or processing facilities.

Where and how you’ll use it: in high-density power environments like manufacturing lines, large machinery cells, or distribution feeders where rapid reconfiguration is an asset. The ST304G is ideal for facilities planning upgrades or expansions, offering a modular path to increase capacity without a full rewiring overhaul.

Why this matters for your operation: copper’s superior conductivity minimizes voltage drop and heat, helping maintain stable equipment performance and reducing cooling demands. The 50% ground bus arrangement supports dependable grounding without sacrificing space, while the plug-in approach shortens install times and minimizes downtime during changes in production layouts.

Compared to traditional rigid layouts, the ST304G delivers tangible efficiency and adaptability: you can extend or re-route power quickly as production needs evolve, without compromising system integrity. For engineers and facility managers seeking a durable, scalable power distribution solution that aligns with industrial standards, this straight-section busway offers a practical, future-ready path to reliable electrical infrastructure.
