Eaton Specification Sheet - CB2033B120480GA
Three-pole, bolted pressure contact switch with charge-before-close and fusible protection delivers robust trip control for large loads. This arrangement enhances protection coordination and reduces nuisance trips, cutting unplanned downtime on critical motors and conveyors. It is well suited for motor control centers, process lines, and heavy industry switchgear where reliability matters. The CB2033B120480GA supports a 2000A amperage rating and 480V system voltage, enabling direct protection of high-current feeders. By consolidating protection into a single assembly, maintenance routines become simpler and spare parts inventories smaller. Bottom-feed configuration with fusible elements reduces wiring complexity and shortens installation time. The unit's 120V control voltage integrates with standard plant power schemes to simplify control wiring. UL Listed certification and NEMA compatibility (1, 3R, 4, 12) extend its versatility across indoor and outdoor installations. The 16 in length, 32 in height, and 24 in width create a sturdy footprint suitable for robust switchgear mounting, with a weight of 190 lb signaling a solid, serviceable unit. Ground fault options, blown fuse detection, and auxiliary contact provisions are available to meet more demanding protection schemes and diagnostics. These features translate to measurable business value: fewer outages, faster troubleshooting, and easier regulatory compliance for plant-wide protection. The Eaton CB2033B120480GA integrates with Kirk provisions and auxiliary contacts to support future expansion while maintaining compatibility with existing equipment and wiring practices.
