Eaton CB1633B120208ARCT Bolted pressure switch - UL Listed
Part Number: CB1633B120208ARCT
Quick Summary
CB1633B120208ARCT is a bolted pressure contact switch designed for three-pole protection in 208V industrial power systems. Maintenance teams often struggle with trip-indication ambiguity, slow fault isolation, and compatibility gaps when upgrading legacy protection gear. UL Listed certification supports electrical safety compliance, while NEMA ratings for enclosures 1, 3R, 4, and 12 provide installation flexibility across harsh environments. This Eaton solution delivers high-current protection with a bottom-feed configuration and optional ground fault relay, auxiliary contacts, and provisions for single-phase protection, helping you reduce downtime and extend equipment life. By aligning with typical low-voltage distribution practices and Eaton switching devices, CB1633B120208ARCT strengthens reliability and streamlines procurement for facilities engineering and maintenance teams.
