Eaton Specification Sheet - CB3033B1204806
Feature → Business Impact → Application: The pringle bolted pressure contact switch delivers a 3000A amperage rating, enabling safe interruption of large feeders and reducing the risk of arc flash during fault clearing. This translates to improved plant safety metrics and lower maintenance costs in high-load applications. It’s ideal for large switchgear banks in steel mills, data centers, and process industries where uptime is critical and feeder reliability is non-negotiable. Feature → Business Impact → Application: A 480 V system voltage with 120 V control enables seamless integration with standard plant control circuits, reducing interface complexity and wiring errors during installation in new builds or retrofits. This supports rapid deployment in manufacturing lines and distribution panels. Feature → Business Impact → Application: NEMA 1, 3R, 4, 12 ratings provide broad environmental resilience—from indoor control rooms to outdoor enclosures—minimizing protective enclosure requirements and enabling flexible siting in harsh environments. Feature → Business Impact → Application: Bottom feed and bottom fuse configuration simplify panel layout, shorten wiring runs, and improve serviceability in compact switchgear assemblies used in heavy manufacturing. Feature → Business Impact → Application: Electrical trip with charge-before-close offers safer, more predictable switching with reduced inrush; this cuts cycle-time and extends equipment life in high-demand motor control centers. Feature → Business Impact → Application: Optional Ground Fault Relay, blown fuse detection, and auxiliary provisions enable enhanced fault diagnostics and compliance with modern protection schemes, supporting predictive maintenance programs and reducing unplanned downtime.
