Eaton Specification Sheet - CB2033B120480KGR5
High-current, capacitor-trip protection is engineered for large feeders, delivering a swift fault clear and reducing arc risk. This feature translates to lower downtime and improved equipment longevity in motor control centers, enabling safer startup with reduced maintenance overhead. The interlock and charge-before-close mechanism prevents unintended energization, supporting safe commissioning in high-stakes environments. Ground fault protection with an integrated control power transformer enhances detection coverage, helping compliance with protective relay schemes and minimizing unplanned outages. The three-pole, 1NO-1NC design with bottom feed simplifies wiring layouts, reduces panel depth requirements, and accelerates installation in retrofit projects. UL Listed with NEMA 1, 3R, 4, 12 compatibility provides straightforward enclosure selection, while optional Ground Fault Relay and Blown Fuse Detection extend protection without adding complex wiring.
