Eaton CB2533T120480K Bolted Pressure Switch - UL Listed

The CB2533T120480K is engineered for high-current protection, delivering up to 2500 A to safeguard feeders and switchgear while reducing nuisance fuse trips and unplanned downtime. This translates to measurable uptime and improved reliability in demanding industrial environments where power continuity is critical. The device combines a 480 V system voltage with a 120 V control voltage, enabling straightforward compatibility with standard plant controls and motor starters, minimizing the need for custom wiring. Its three-pole, three-wire configuration supports robust fault clearing and predictable switching behavior, supporting safer lockout/tagout and easier maintenance. The top feed/fuse configuration simplifies integration into existing top-feed enclosures, while optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contacts provisions expand protection and monitoring capabilities without sacrificing simplicity of installation. The interlock feature adds an extra layer of safety, helping prevent accidental arcing during maintenance or during close sequencing in complex switchgear assemblies. Manufacturers benefit from documented reliability, a clear upgrade path for aging fleets, and better compliance alignment with standard electrical codes. In practice, this translates to lower total cost of ownership through improved fault visibility, easier spare parts planning, and reduced maintenance labor over the life of the installation.
