Eaton CB2033B120480KG Pringle bolted pressure contact UL
Part Number: CB2033B120480KG
Quick Summary
The Eaton CB2033B120480KG is a high-current pressure contact switch for switchgear protection. Downtime from miscoordination and slow fault isolation costs time and money, so reliable interlock, ground fault sensing, and fusible protection matter. UL Listed certification and broad NEMA compatibility (1, 3R, 4, 12) support safe operation in challenging environments. With bottom-feed installation and three-pole operation, you gain easier wiring, improved reliability, and a clearer path to regulatory compliance for large electric installations.

Eaton Specification Sheet - CB2033B120480KG
Amperage rating up to 2000A enables handling of large motor loads without frequent device retirement, reducing upstream fuse trips and extending service life across switchgear. This enhances uptime and lowers maintenance costs in MCCs and distribution panels. The three-pole, 3-wire configuration supports robust three-phase protection at 480V, simplifying wiring topology and improving coordination with upstream protection devices for critical loads. Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact Provisions provide additional monitoring and safety, helping meet strict safety standards while reducing unplanned outages. Fusible protection offers selective coordination, fast fault isolation, and improved overall system reliability in harsh environments. Bottom-feed design and Kirk/auxiliary provisions enable straightforward retrofit and modular expansion in existing switchgear.
