Eaton CB4033T120480GA Pringle bolted pressure switch - UL

High amperage capability and fusible protection allow a single CB4033T120480GA to guard large main circuits, reducing the need for parallel devices and minimizing panel footprint. The result is lower capital cost and simplified protective coordination in heavy industrial feeders where uptime is critical. The combination of 120 V control voltage and a 480 V system rating gives straightforward control-wiring integration with standard transformers and relays, cutting installation time and potential control faults. In practice, this means faster fault clearance and safer startups across process lines and manufacturing cells. Top feed configuration with a three-pole, three-wire arrangement simplifies wiring layouts and reduces staggered connection points inside switchgear, improving phase balance and retrofit ease in legacy systems. UL Listed certification paired with compatible NEMA 1, 3R, 4, and 12 enclosure ratings provides compliance confidence and durable operation in varied environments, supporting audits and standardization across facilities. Optional features such as Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, and Auxiliary Contact Provisions let you tailor protection without replacing the entire scheme, improving maintenance predictability and diagnostics. The substantial weight and footprint of 390 lb and 17 x 28 x 40 in require careful handling and coordination with rigging and dock scheduling, but deliver a rugged, reliable main-protection device designed for high-current systems that minimizes downtime and extends service life.
