Eaton CB2533T120480AX5 Pringle bolted pressure switch - UL
Part Number: CB2533T120480AX5
Quick Summary
Eaton pringle bolted pressure contact switch provides reliable trip protection for three-pole industrial circuits. Maintenance teams often contend with nuisance trips, ground-fault confusion, and limited accessory options. UL Listed certification ensures safety compliance, while NEMA 1/3R/4/12 ratings support versatile enclosure choices and rugged environments. Fusible protection and top-feed configuration simplify installation and improve fault isolation in panelboards and switchgear. It also supports optional ground fault relays, auxiliary contacts, and Kirk provisions, delivering faster deployment and lower lifecycle costs for capital projects. For engineers and procurement teams, this translates to predictable performance, easier maintenance planning, and reduced downtime.
