Eaton CB4033T120480GRAX6 Pringle bolted pressure switch-UL
Part Number: CB4033T120480GRAX6
Quick Summary
Eaton pringle bolted pressure contact switch protects heavy-duty power systems in industrial applications. Engineers often wrestle with nuisance trips and slow fault isolation; this model uses a capacitor trip device (SPVR) to speed relief and improve selective actuation. UL Listed certification paired with robust NEMA ratings (1, 3R, 4, 12) supports reliable enclosure protection in varied environments. With a 4000 A amperage rating, 480 V system voltage, and 120 V control voltage, it delivers dependable protection for large switchgear. The top-feed configuration and fusible protection translate to quicker commissioning, better fault clearance, and lower total cost of ownership for industrial facilities and OEM applications.
