FAQs

installation requires following the top-feed, three-pole configuration and coordinating the 1NO-1NC contacts with the control circuitry. Use proper torque on terminal connections, verify correct wiring of the top feed, and ensure the fusible protection is configured per the Eaton spec sheet. Safety interlocks and auxiliary contact provisions should be wired according to the control schematic to prevent misoperations during maintenance.
Key specs include the 2000A amperage rating, 480V system voltage, and 120V control voltage, with a fusible protection scheme. The device supports NEMA 1, 3R, 4, 12 enclosures, UL Listing, and a three-pole, three-wire configuration that together deliver dependable protection across harsh industrial environments and reduce false trips or nuisance faults.
Yes, the catalog notes indicate optional ground fault relay, blown fuse detection, single-phase protection, and auxiliary contact provisions are available. These options allow you to tailor the protection scheme to meet specific safety and diagnostic requirements, improving fault isolation and maintenance planning without replacing the switchbase.
This switch is UL Listed, reinforcing safety compliance for industrial environments. It also supports NEMA ratings 1, 3R, 4, and 12, which describe enclosure protection and environmental suitability. For project qualification, reference Eaton's specification sheets to confirm compatibility with local codes and any site-specific requirements.
The CB2033T120480AX5’s 2000A rating and robust construction reduce the likelihood of premature failures in high-current applications, lowering downtime and replacement costs. A one-year warranty from installation or eighteen months from shipment provides purchasing assurance. Availability of auxiliary contacts and diagnostic options further supports proactive maintenance and faster fault resolution.
