Eaton CST133G - 100A, 600V, 3-Phase, 3 ft Plug-In Busway Section (Copper) | AmpState

Designed for compact, high-demand power distribution, the Eaton CST133G is a 3 ft copper plug-in busway straight section engineered for tight layouts. With a 100 A current rating and 600 V maximum, this 3-phase segment delivers dependable, low-impedance power where space is at a premium. The copper conductors ensure efficient heat dissipation and consistent voltage delivery across all phases, even under sustained loading.

This short, plug-in busway section slides seamlessly into an existing run, enabling fast expansions and clean, continuous power without exposed wiring. The 50% internal ground bar is purposefully integrated to optimize grounding in confined installations, simplifying transitions and new connections while maintaining robust equipment grounding.

Ideal use scenarios

• Data centers and server rooms needing modular, scalable power distribution while preserving floor space.
• Industrial environments with tight equipment layouts or frequent reconfigurations.
• Retrofit projects where adding length to a busway run must be achieved without bulky, time-consuming wiring.
• Switchgear and panel area expansions where a compact 3 ft segment can bridge gaps or navigate around obstacles.

Practical tips for installation and care

• Plan runs to take advantage of the 3 ft length for efficient transitions between sections, reducing the need for intermediate splices.
• Verify compatibility with existing plug-in busway components in your system to ensure a clean, secure connection.
• Keep contact surfaces clean and dry during installation to maintain optimal conductivity and grounding performance.
• Store and handle in a dry environment to preserve copper conductors and prevent galvanic corrosion on connectors.
