Eaton CB1233T120480G6 Pressure Contact Switch - UL Listed
Part Number: CB1233T120480G6
Quick Summary
The Eaton CB1233T120480G6 Pressure Contact Switch provides reliable protection for industrial switchgear and motor control centers. Engineers often battle nuisance trips and slow fault detection when protective devices lack integrated ground fault monitoring or fast-trip capability. UL Listed safety certification, along with NEMA 1, 3R, 4, and 12 enclosure ratings, helps ensure dependable performance in harsh environments. Designed for top-feed, three-pole configurations, it supports 1200A at 480V with a 120V control voltage, aligning with common MCC and panel layouts. Optional Ground Fault Relay, Blown Fuse Detection, and Single Phase Protection simplify compliance, while auxiliary contact provisions and Kirk provisions ease integration and future expansion.
