Eaton Specification Sheet - CB1633B120208KG
High-current capability enables direct switching of large motors and feeders, reducing wiring complexity and panel density while supporting up to 1600A at 208V. This translates to improved efficiency and reduced heat losses in power distribution, ideal for medium- to large-switchgear applications in manufacturing plants. Bottom feed, three-pole configuration with fusible protection simplifies wiring and enhances fault isolation, cutting service time after faults and improving safety. The interlock with a charge-before-close mechanism prevents unsafe energization, lowering the risk of operator error during startup sequencing. Optional ground fault relay, blown fuse detection, and auxiliary contact provisions provide tailored protection, faster diagnostics, and easier integration with existing control circuits. Built to meet UL Listed standards and multiple NEMA enclosure ratings, the device supports reliable operation in challenging environments while aligning with Eaton’s protective-device ecosystem for maintenance and lifecycle planning. The unit’s robust construction, 16 in length, 24 in width, 32 in height, and 200 lb weight, validates suitability for permanent installations in control panels and switchgear housing, with bottom-feed wiring for straightforward installation in retrofits and new builds.
