Eaton CST135G - 100A, 600V, 3-Phase, 5 ft Plug-In Busway Section (Copper) | AmpState

The Eaton CST135G is a precision-built 100 A, 600 V, 3-phase copper plug-in busway straight section designed to streamline power distribution in compact spaces. At 5 feet long, it slides seamlessly into modular busway runs, delivering reliable, low-impedance performance where space is at a premium.

Why the CST135G stands out

• Copper conductors for efficient power transfer: Low resistance and excellent thermal performance translate to stable voltage delivery and reduced energy losses in everyday operation.
• Plug-in straight section: Ready-to-connect 5 ft length that fits neatly into existing busway networks, enabling faster project completion and simpler reconfiguration.
• 50% internal ground bar for compact runs: A smart, space-saving grounding design that preserves room in confined panels and enclosures without compromising safety or performance.
• Three-phase, 100A capability: Ideal for balanced distribution of motors, drives, and office/industrial loads that demand dependable 3-phase power.
• Rugged, ready-to-install solution: Engineered for durable operation in demanding environments, with a construction that supports consistent electrical contact and long service life.

What problems it solves

• Space constraints in panels and switchgear: The partial-ground-bar design reduces enclosure footprint while maintaining grounding effectiveness.
• Complex wiring and assembly: Plug-in sections simplify installation and future expansions, cutting commissioning time.
• Voltage drop and inefficiency in high-load scenarios: Copper conductors paired with precise manufacturing minimize losses and maintain stable operation under heavy, multi-phase loads.
• Maintenance and reliability in critical facilities: A robust busway approach supports reliable power delivery for data centers, manufacturing lines, and commercial spaces.
