Eaton CB1633B120208AXCT6 Bolted Pressure Switch - UL 977
Part Number: CB1633B120208AXCT6
Quick Summary
Eaton pringle bolted pressure contact switch delivers high-capacity control for industrial switchgear and CBC panels. This model is designed to reduce panel outages by providing reliable trip action and clear fault indication in demanding environments. A common pain point is selecting a switch that mates with bottom-feed configurations while delivering robust protection; this unit handles that with a bottom feed, three-pole arrangement and fusible protection. Certifications such as UL 977 and compatible NEMA ratings (NEMA 1, 3R, 4, 12) support both safety and compliance. Industrial teams gain uptime and predictable maintenance costs by standardizing on a single, field-proven solution with a 208 V system voltage and 1600 A rating, combining performance with ease of integration.
