Eaton Specification Sheet - CB2033T120480KRAR
Feature → Business Impact → Application: Three-pole, three-wire design supports 2000A amperage and 480V system voltage, enabling large motor loads and feeders to start and run smoothly with reduced heat and trip chatter in demanding environments. This translates to higher line efficiency and measurable uptime gains in switchgear assemblies and control panels. Feature → Business Impact → Application: Top feed fuse configuration paired with an electrical trip mechanism and an interlock enhances protective coordination, delivering faster fault clearing and safer maintenance in large-distribution panels and MCCs. Feature → Business Impact → Application: Interlock with capacitor trip device SPVR and three normally-on indicator lights (BFD) mitigate mistrips and provide clearer status signals, simplifying operator training and reducing downtime in critical line start sequences. Feature → Business Impact → Application: Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact Provisions extend protection, enabling compliance with plant safety policies and reducing unplanned outages in harsh production environments. Feature → Business Impact → Application: UL Listed and NEMA-rated enclosure compatibility (1, 3R, 4, 12) ensure robust performance across diverse sites, simplifying procurement and installation in refurbished or new-build facilities. Feature → Business Impact → Application: Weight and footprint considerations, with a 16 in L × 28 in H × 24 in W footprint and 180 lb weight, inform mounting and space planning for retrofit projects and new installations, improving overall project estimates and installation timelines.
