Eaton CB1633T120480 Bolted Pressure Switch - UL Listed
Part Number: CB1633T120480
Quick Summary
Eaton CB1633T120480 is a bolted pressure contact switch for high‑amp protection in industrial power systems. When downtime, nuisance trips, or difficult wiring threaten uptime, you need a reliable, code‑compliant solution. UL Listed safety certification and robust NEMA enclosure ratings (1, 3R, 4, 12) support safe operation in harsh environments. In practice, this means faster installs, better protection for high-current circuits, and a clear path to regulatory compliance. These ratings align with critical industry standards and make the CB1633T120480 suitable for demanding control panels. Designed for 1600A, 480V systems with top feed and fusible protection, it supports scalable power architectures. This combination supports faster field installs and reduces lifecycle costs.

FAQs
Yes. The CB1633T120480 is designed for top-feed, three-pole operation with three wires, matching common industrial power distribution schemes. This simplifies panel layout and ensures reliable main-disconnect performance for 480V systems while supporting three‑phase power architectures.
The product is UL Listed and rated for NEMA enclosure types 1, 3R, 4, and 12. These certifications and ratings make it well-suited for harsh industrial environments, including manufacturing floors, processing plants, and outdoor or damp locations where reliable protection is required.
Yes. Catalog notes indicate optional Ground Fault Relay and Blown Fuse Detection are available, along with auxiliary contact provisions. These options integrate with control systems for improved fault diagnostics and safer operation, enabling enhanced protection in smart panels and MCCs.
Installers should plan for proper enclosure space, secure mounting for a 175 lb device, and compliant wiring for 480V power with a 120V control circuit. The switch’s three-pole, top-feed configuration and charge-before-close mechanism support safe energization, while UL/NEMA ratings help ensure regulatory compliance in demanding environments.
The high amperage rating reduces the need for multiple fuses and minimizes nuisance trips, lowering downtime and maintenance costs. With a one-year warranty (or 18 months from shipment) and optional diagnostics like ground fault and blown-fuse detection, the device offers predictable lifecycle costs and improved availability in critical power applications.
