Eaton Specification Sheet - CB2033T120480A9CT5
High-current protection is built into CB2033T120480A9CT5, delivering reliable interruption up to 2000A for demanding equipment. This translates to reduced fault duration and minimized arc flash exposure for operators, ultimately lowering maintenance costs. The design suits switchgear and motor control centers in heavy-industry facilities where robust protection against short circuits is critical. UL Listed certification and compatible NEMA ratings (1, 3R, 4, 12) provide regulatory confidence and installation flexibility across enclosures. With three-pole operation and top-feed wiring, installation is straightforward in constrained spaces and supports quick replacement during plant uptime windows. The three-pole, top-feed configuration supports robust protection for three-phase systems while accommodating fusible protection as required. The 1NO-1NC contact configuration enables simple control logic and auxiliary revision without adding complexity to the panel. With a 2000A amperage rating, 480V system voltage, and 120V control voltage, this switch scales to demanding applications in switchgear and motor control centers, reducing sizing uncertainty and inventory diversity. Its fusible protection and charge-before-close mechanism enhance safety and reliability during startup and load changes. Optional features such as ground fault relay, blown fuse detection, auxiliary provisions, and power transformer compatibility extend lifecycle value and support modernization projects.
