Eaton CB2533T120480A Pringle bolted switch - UL Listed
Part Number: CB2533T120480A
Quick Summary
CB2533T120480A is a high-capacity bolted pressure contact switch for industrial distribution panels. Engineers often struggle with reliable protection in high-current, multi-pole systems where nuisance trips and slow diagnostics drive unplanned downtime. UL Listed and NEMA ratings for 1, 3R, 4, and 12 environments ensure compliance across indoor switchgear, outdoor enclosures, and rugged plant floors. The device supports 2500A current at 480V with a 120V control circuit, top-feed fuse configuration, and optional ground fault relay options to tailor protection to exact applications. With its three-pole, three-wire design and Kirk/Auxiliary provision options, it plugs into common panel layouts, delivering improved reliability and lower total cost of ownership.
