Eaton Specification Sheet - CB4033T120480R
The CB4033T120480R delivers high-current protection with a 4000A amperage rating, enabling safe interruption of large feeder circuits. This capability translates into improved system reliability and reduced risk of downstream faults, which is critical for large industrial panels and process lines. The 120 V control voltage ensures seamless integration with standard plant controls and relays, minimizing wiring complexity and control panel footprint. NEMA ratings of 1, 3R, 4, and 12 provide enclosure compatibility across diverse environments, allowing quick replacement in existing installations without enclosure modifications. The top feed configuration and fusible protection simplify installation in top-fed switchgear, reducing wiring depth and production downtime during retrofits. Optional features, including Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact Provisions, expand protection and diagnostic capability, lowering maintenance costs and improving uptime. With Kirk provisions and accessory options, integration with existing safety interlocks and control circuits is straightforward, helping engineers achieve compliant, robust protection with fewer parts and less downtime.
