Eaton CB1233T120480GRAX5 Pringle bolted switch - UL
Part Number: CB1233T120480GRAX5
Quick Summary
Eaton pringle bolted pressure contact switch is a high-capacity protection device for three-phase motor circuits in industrial plants. It provides reliable protection in harsh environments and reduces downtime by delivering decisive tripping when faults occur. UL Listed safety certification and NEMA compatibility with 1, 3R, 4, and 12 enclosures ensure flexible deployment across manufacturing floors, outdoors, and wash-down areas. The design supports single-phase protection variants and auxiliary provisions, while the 1200A rating and 480V system compatibility meet demanding panel requirements. Integrating SPVR with a capacitor trip device and optional ground-fault relay streamlines compliance, lowers wiring complexity, and supports safer, more efficient electrical installations.
