FAQs
To install CB2033T120480K5, verify enclosure rating and ensure NEMA compatibility, mount with top-feed wiring, and connect three conductors to the 1NO-1NC contacts. Use the fusible protection as specified and follow Eaton installation guidelines. If needed, add the optional Ground Fault Relay or Auxiliary Contacts to meet site safety requirements. This approach supports safe energization sequencing and reduces commissioning time in large control panels.
Key specs include a 2000A amperage rating, 120V control voltage, 480V system voltage, three-pole configuration, and a 1NO-1NC contact arrangement. It features top-feed, fusible protection, and no ground fault path by default. The unit is compatible with NEMA 1, 3R, 4, and 12 enclosures, making it suitable for demanding industrial environments and large electrical installations.
Yes. The CB2033T120480K5 is designed for use in NEMA-rated enclosures, including NEMA 4 environments, when installed in compliant enclosures. UL Listed certification further supports safety and reliability in harsh conditions. The top-feed wiring and fusible protection add to its suitability for outdoor or damp locations where robust interlock protection is required.
The CB2033T120480K5 carries UL Listed certification, indicating compliance with recognized safety standards for industrial switchgear. It also supports broad enclosure compatibility with NEMA ratings (1, 3R, 4, 12). Optional features such as Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contacts can help meet specific regulatory or risk-management requirements in regulated industries.
Upgrading to CB2033T120480K5 can reduce downtime by providing reliable interlock protection and fault-detection options in one unit. Its high amperage rating minimizes the number of devices and simplifies wiring, while top-feed installation and optional safety features shorten commissioning time and reduce spare-parts inventory. Overall, expect lower maintenance costs and improved system availability over the lifecycle.
