Eaton CB1633T120480A9 Bolted pressure switch - UL Listed
Part Number: CB1633T120480A9
Quick Summary
The Eaton CB1633T120480A9 is a bolted pressure contact switch designed for high-current motor protection in industrial power distribution. In many facilities, unreliable protection and slow fault clearance lead to unplanned downtime and expensive repairs. This model is UL Listed and compatible with NEMA enclosures (NEMA 1, 3R, 4, 12) to support diverse installation needs. The combination of fusible protection, a three-pole configuration, and the charge-before-close mechanism delivers reliable switching and faster fault isolation. By integrating top-feed wiring and optional ground fault/auxiliary provisions, this solution reduces maintenance complexity while delivering safer, compliant power-distribution performance for industrial control panels.
