Eaton CB1633T120480K5 Bolted Pressure Switch - UL Listed
Part Number: CB1633T120480K5
Quick Summary
CB1633T120480K5 bolted pressure switch provides reliable, high-current interlock protection for switchgear and motor starters. Engineers often struggle with downtime caused by incomplete protection in top-feed, fusible configurations and complex wiring. UL Listed certification, NEMA compatibility, and a 1600A rating (120 V control, 480 V system) reinforce safety and regulatory compliance in demanding environments. As a robust power-distribution solution, it supports safer maintenance, simpler spares planning, and dependable protection in industrial control panels. Optional Ground Fault Relay and Auxiliary Contact provisions offer scalable protection for future upgrades without replacing the core device. The three-pole, 1NO-1NC configuration with top-feed wiring further simplifies installation and reduces panel footprint in demanding industrial settings.
