Eaton CB1633B120480G6 Pringle bolted pressure switch - UL Listed
Part Number: CB1633B120480G6
Quick Summary
The Eaton CB1633B120480G6 pringle bolted pressure contact switch provides high-current protection for industrial feeders. Engineers wrestle with reliable fault detection and fuse coordination in demanding switchgear assemblies. UL Listed certification underscores safety compliance, while broad NEMA compatibility (NEMA 1, 3R, 4, 12) supports rugged environments. In practice, this means faster commissioning, lower downtime, and consistent protection across industrial control panels. With a 1600A amperage rating and a 480V system voltage, the switch supports large feeders with fewer components, reducing panel footprint and wiring complexity. This translates to lower installation labor, easier maintenance, and faster ROI for capital projects in manufacturing and processing environments.

Eaton Specification Sheet - CB1633B120480G6
Three-pole, bottom-feed design provides stable switching in demanding installations. This reduces wiring errors and speeds commissioning in crowded panels, ideal for switchgear, motor control centers, and heavy-duty feeders. Fusible protection enhances fault energy management, enabling simpler fuse coordination and safer shutdowns in high-current systems. The 120 V control voltage aligns with standard control circuits, reducing the need for extensive transformers and simplifying panel wiring for automated processes. Optional ground fault relay and auxiliary contacts can tailor protection to specific safety standards and plant layouts, improving fault isolation and compliance. UL Listed certification paired with broad NEMA enclosure compatibility ensures safe operation in diverse environments, from clean rooms to outdoor switchgear housings. The device footprint and rugged enclosure support straightforward retrofits and long-term lifecycle cost reductions in large facilities.

FAQs
When installing the CB1633B120480G6, verify bottom-feed configuration and three-pole wiring as per the catalog notes. Ensure the 120 V control circuit is compatible with your control power transformer, and confirm enclosure allowances for the 16x32x24 in footprint. The UL Listed unit integrates with Eaton switching devices, simplifying retrofit and standardizing protective coordination across panels.
CB1633B120480G6 handles up to 1600A with a 480V system rating and fusible protection, delivering reliable tripping in fault events. The three-pole, bottom-feed design ensures consistent interlock and minimizes phase-to-phase faults. Its UL Listed status assures safety compliance, while NEMA compatibility supports installation in diverse enclosures, reducing the need for custom solutions in high-current switchgear.
Yes. The unit operates with a 120 V control voltage, simplifying integration with standard control circuits and relays in industrial automation. This compatibility reduces the need for extra transformers, streamlines wiring, and supports faster commissioning in control panels and motor control centers.
Yes. Catalog notes indicate optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions are available. These options let you tailor protection to plant-specific safety requirements, improve fault detection, and enhance monitoring without replacing the main switch.
