Eaton CB1233B120480KG Pringle bolted switch - UL Listed
Part Number: CB1233B120480KG
Quick Summary
Eaton CB1233B120480KG is a bolted pressure contact switch designed for heavy-duty protection in industrial electrical systems. Engineers often confront downtime and safety risks when protective devices aren’t robust or properly integrated; this unit addresses that by combining interlock capability with ground fault protection for reliable operation. UL Listed certification and NEMA-rated enclosure compatibility (NEMA 1, 3R, 4, 12) provide proven safety and environmental resilience in demanding environments. With support for 120 V control and 480 V system voltage in a three-pole configuration, it scales across large power-distribution panels while reducing wiring complexity. Optional features like ground fault relay, auxiliary contacts, and fuse coordination simplify long-term maintenance and compliance reporting for facilities and OEMs alike.
