FAQs
Installation requires a top-feed, three-pole configuration with 3 wires and a 120 V control circuit. Ensure the enclosure supports NEMA ratings up to 4, 12, or 3R as applicable. Verify fusible protection and SPVR capacitor trip device are configured per Eaton datasheets, and consider Kirk provisions or auxiliary contact options for expanded control. Follow standard lockout-tagout procedures and refer to the Eaton installation notes for mounting clearances and wiring diagrams. Proper torque on terminal connections is critical to prevent overheating and ensure reliable operation over time.
Key specs include 2000A amperage rating, 480V system voltage, 120V control voltage, and three-pole, three-wire configuration with top feed. It supports fusible protection and is UL Listed. The device accommodates NEMA 1, 3R, 4, and 12 enclosures, making it suitable for both indoor and outdoor applications. Optional Ground Fault Relay and Blown Fuse Detection can be added to enhance safety and fault diagnosis. Always cross-check the control-circuit compatibility with your PLC or motor starter logic before integrating.
Yes, the CB2033T120480R is designed for use in motor control centers and switchgear, with UL Listing and NEMA-rated enclosure compatibility (1, 3R, 4, 12). The top-feed, three-pole design supports high-current protection for large motors, and the SPVR device provides reliable capacitor-assisted tripping. For outdoor or harsh environments, ensure enclosure rating aligns with your location and install optional accessories like Ground Fault Relay or Blown Fuse Detection as needed for extra protection and diagnostics.
The fusible protection combined with a capacitor trip device reduces nuisance trips and extends feeder and motor life, lowering maintenance costs and downtime. UL Listing and optional safety features simplify compliance reporting and reduce regulatory risk. The system’s robust construction and compatibility with large-panel installations support longer service intervals and easier replacement during plant expansions, delivering a favorable total cost of ownership for mission-critical applications.
