Eaton CB3033T120480GA Pringle bolted switch - UL Listed
Part Number: CB3033T120480GA
Quick Summary
Eaton CB3033T120480GA is a high-current bolted pressure switch designed for three-phase protection in industrial power distribution. Maintenance teams often struggle with slow installation, cumbersome wiring, and unreliable fault detection under heavy loads. UL Listed certification guides safety, while the unit’s NEMA ratings—1, 3R, 4, and 12—inform enclosure suitability in varying environments. For panel builders and plant engineers, the combination of top-feed configuration, fusible protection, and 3000A capability translates to faster installation and reduced total cost of ownership. With 480 V system operation and 120 V control voltage, this switch delivers dependable protection alongside compatible integration with optional ground fault, auxiliary contact provisions, and Kirk provisions as needed for complex control schemes.

Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: The CB3033T120480GA delivers 3000A continuous amperage at 480 V system voltage, enabling it to carry heavy start-up currents in large motor feeders without the need for multiple devices, reducing panel footprint and wiring complexity for critical processes in manufacturing and heavy industry. This translates to measurable improvements in efficiency and a lower total cost of ownership when upgrading legacy switchgear. Feature → Business Impact → Application: Top feed fuse configuration simplifies installation in cramped enclosures and streamlines maintenance, reducing commissioning time and risk of wiring errors in new switchgear installations or panel retrofits. Ideal for distribution panels in process lines and utility-rated installations. Feature → Business Impact → Application: Ground fault protection with a control power transformer, plus optional Ground Fault Relay, Blown Fuse Detection, and Single Phase Protection, enhances safety interlocks and fault diagnostics, minimizing downtime and improving risk management in mining, water treatment, and data-center environments. Feature → Business Impact → Application: Three-pole, three-wire architecture with a charge-before-close mechanism delivers reliable coordination during switching, preventing inrush-related damage and enabling safer maintenance procedures in motor control centers and large forklift charging stations. Feature → Business Impact → Application: UL Listed certification combined with robust NEMA ratings (1, 3R, 4, 12) supports compliance with industry standards and retrofit projects, reducing procurement risk for regulated facilities and helping maintain insurance and uptime guarantees. Feature → Business Impact → Application: Optional Kirk provisions and auxiliary contact provisions expand compatibility with modern control architectures, enabling seamless integration with PLCs, distributed safety interlocks, and remote monitoring in automation skids and line side facilities.
