Eaton Specification Sheet - CB2533B120480GAR
Three-pole design with bottom feed and fusible protection ensures safe isolation in high-current applications, reducing fault propagation and enabling straightforward coordination with upstream protection. This translates to shorter downtime, simpler panel layouts, and improved reliability in 480 V switchgear, motor control centers, and distribution panels. The charge-before-close switch type minimizes inrush and sequencing issues during energization, supporting safer start-ups and extended contact life, while enabling compliant operation in demanding environments. Optional ground fault relay, blown fuse detection, and single-phase protection give system integrators flexibility to meet safety standards and reduce nuisance trips. Kirk provisions and auxiliary contact provisions add integration versatility, streamlining retrofit and expansion projects. With 235 lb weight and bottom-feed configuration, installation is straightforward in tight electrical rooms and existing enclosures, lowering installation time and labor costs. OEMs value the warranty terms and UL Listed certification as a risk-reduction lever for long-term service contracts and OEM supply chains.
