Eaton Specification Sheet - CB4033T120208RA
With a 4000 A amperage rating, the CB4033T120208RA supports high-current feeders without compromising protection, reducing busbar stress and preventing unexpected trips in demanding applications such as large motor drives and process lines. In panel boards and MCCs, its three-pole, three-wire configuration simplifies wiring, speeding installation and facilitating future maintenance. The single-phase voltage relay with capacitor trip (SPVR) and the fusible protection scheme deliver selective protection while the BFD with three indicator lights provides immediate status visibility for operators and maintenance teams. Optional Ground Fault Relay, auxiliary contact provisions, Kirk provisions, and blowing-fuse detection are catalog-enabled, enabling tailored protection schemes without reworking existing gear. The top-feed design and UL/NEMA-compliant construction help installers coordinate with existing enclosures, while the hefty dimensions and weight (17 in L, 40 in W, 28 in H; 390 lb) enable secure mounting in robust panels.
