Eaton CB1633T120480KG7NF Bolted Pressure Contact Switch - UL Listed
Part Number: CB1633T120480KG7NF
Quick Summary
Eaton CB1633T120480KG7NF bolted pressure contact switch provides interlock protection for three-pole industrial control panels. End users too often suffer costly downtime from misoperation during power-up; this device uses a charge-before-close sequence to prevent accidental energizing. UL Listed safety certification accompanies it, while NEMA ratings 1, 3R, 4, and 12 support reliable operation in indoor, damp, and harsh environments. This model's 480 V system capability and 1600 A amperage rating deliver robust protection with reduced maintenance in industrial control systems. The top-feed configuration, ground fault with transformer, and optional features like ground fault relay and auxiliary contacts enable safer, faster installation in panel assemblies.
