Quick Summary

Eaton pringle bolted pressure contact switch is a high-capacity protection device designed for industrial switchgear. For engineers facing complex wiring, coordinating a control power transformer, grounding, and fuse-protection across large feeders can create project delays and commissioning risk. UL Listed with NEMA 1, 3R, 4, and 12 enclosure ratings, and a three-pole, three-wire configuration, delivers proven reliability in harsh environments. By combining top-feed, fusible protection, and a control power transformer, this unit streamlines installation and helps meet safety and compliance goals while supporting scalable power distribution.

High amperage rating and system voltage provide a single-protection solution for heavy feeder circuits. This 1600A rating, 480V system voltage, and 120V control voltage translate to fewer devices, lower installation time, and improved fault containment. Application: main power feeds in industrial switchgear, data centers, and manufacturing lines where reliability and quick isolation are critical. Top feed and fuse configuration simplify wiring and panel layout. The top-feed design minimizes bus work and allows straightforward replacement or upgrade within existing switchgear buses. Application: new installations or retrofits in controlled environments where fast commissioning and reduced wiring complexity are priorities. Ground fault with control power transformer offers integrated protection and control power. The provision both enhances safety and ensures control relays have stable power during faults. Application: protection schemes that require reliable auxiliary power for signaling and interlocking in three-wire, three-pole configurations. Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions provide customization. Business impact: tailored protection schemes to match plant standards, improve downtime statistics, and support regulatory compliance. Application: utility substations, OEM switchgear builds, and industrial plants needing configurable protection sets. UL Listed with NEMA ratings (1, 3R, 4, 12) confirms compliance and environmental versatility. This enclosure compatibility supports indoor and outdoor installations and harsh environments. Application: rugged installations in manufacturing floors, outdoors, or service corridors with demanding environmental conditions. Rugged physical attributes and warranty. Product weight 175 lb; dimensions 16 in length, 28 in height, 24 in width; warranty policy 1 year from installation or 18 months from shipment. This ensures total cost of ownership is predictable. Application: procurement decisions requiring documented warranty and lifecycle planning.

FAQs

For CB1633T120480G installations, ensure adequate clearance for the 16 inch depth and 28 inch height, and prepare for a 175 lb unit. Top-feed mounting simplifies bus work, but provide solid panel supports and room for wiring to the control power transformer and ground fault options. Verify compatibility with existing auxiliary contacts and kirk provisions if used.
The 1600A amperage rating supports large feeder currents with robust fault isolation, while 480V system voltage aligns with heavy-duty distribution equipment. The 120V control voltage powers the transformer and relays for control circuits, improving reliability during faults. Together, these specs reduce the need for multiple devices and simplify coordination with upstream protection schemes.
Yes. Catalog notes indicate options for Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions are AVAILABLE. This enables tailoring protection schemes to plant standards, enhancing safety interlocks, monitoring, and ease of integration with plant PLCs and protective relays.
The device is UL Listed and carries NEMA ratings 1, 3R, 4, and 12. These certifications and enclosures indicate suitability for indoor use, outdoor or damp environments, and protection against dust, rain, and impact. They support compliance with industry standards and ease procurement in regulated industries.
The unit ships with a one-year warranty from installation or an 18-month window from shipment. ROI benefits come from reduced wiring complexity, fewer components, and improved uptime due to integrated protections. Routine maintenance should focus on fuse condition, ground fault reliability, and ensuring the control transformer remains powered for signaling and interlocks.
