Eaton CB3033T120480G14 Pringle Pressure Contact Switch - UL
Part Number: CB3033T120480G14
Quick Summary
The Eaton CB3033T120480G14 pressure contact switch delivers high-current control for industrial power distribution. In demanding environments, reliable fault protection and timely tripping can be hard to guarantee without rugged, purpose-built hardware. This unit carries UL Listed safety certification and is compatible with NEMA 1, 3R, 4, and 12 enclosures, supporting a wide range of installations. With a 120 V control voltage and 480 V system voltage, it enables robust control architectures while reducing complex wiring. Designed for three-pole, three-wire applications, it accommodates up to 3000 A and features a top-feed fusible configuration for concise panel integration. The combination of a control power transformer and three NO-3 NC contacts delivers reliable operation and long-term lifecycle value for modern switchgear and motor control centers.
