Quick Summary

Eaton CB1633T120480PAX7C is a bolted pressure contact switch for high-current, three-pole protection in industrial power circuits. Many engineers wrestle with mis-trips and outages due to inadequate protection coordination in large control panels. UL Listed certification, NEMA 1/3R/4/12 ratings, and optional capacitor-trip device strengthen safety, compliance, and rugged operation. This solution combines rugged protection with flexible mounting and long service life to reduce maintenance costs and downtime. Its 1600 A amperage rating and 120 V control voltage align with common industrial power architectures, simplifying procurement and maintenance planning.
