Eaton CB2533B120480GAX Pringle bolted switch - UL Listed
Part Number: CB2533B120480GAX
Quick Summary
Eaton CB2533B120480GAX is a bolted pressure contact switch designed for high-current motor protection in industrial power distribution. This solution addresses the challenge of reliable fault isolation in large switchgear, where delayed trips can lead to costly, unplanned downtime. The unit supports heavy-duty applications with a 2500A amperage rating, 480V system voltage, and 120V control voltage, delivering fast, controlled trips. It carries UL Listed certification and supports robust NEMA ratings for diverse environments. Optional features such as Ground Fault Relay and Blown Fuse Detection help meet safety and compliance goals while minimizing nuisance trips. For contractors and OEMs, this translates to faster commissioning and lower lifecycle costs, with scalable protection options for evolving facilities.
