FAQs

CB2033B120480KA is rated for 2000 A with a 480 V system and a 120 V control voltage. It is a three-pole, three-wire configuration designed for high-current protection in industrial control panels, switchgear, and motor control centers. The multi-voltage capability supports both power and control circuits within a single protective device.
The interlock feature ensures safe maintenance by preventing unintended operation, while the three normally-on indicator lights provide continuous status visibility. Note that this configuration does not trip automatically from the lights; the mechanism remains governed by the fuse and protective contacts. This aids operators in quickly assessing the switch state without opening the enclosure.
Yes, CB2033B120480KA is UL Listed, offering compliance with recognized safety standards. It supports multiple NEMA enclosure ratings, specifically NEMA 1, NEMA 3R, NEMA 4, and NEMA 12, enabling versatile mounting in a variety of indoor and outdoor industrial environments with different ingress protection needs.
For bottom-feed installations, CB2033B120480KA uses bottom feed fuse configuration with three wires and three poles. This arrangement simplifies wiring, enhances fault isolation, and aligns with standard safety practices for high-current switchgear. Ensure proper mounting in compatible enclosures and correct alignment with auxiliary provisions as specified by Eaton documentation.
Eaton provides a warranty of one year from the date of installation or eighteen months from shipment, whichever occurs first. For maintenance, inspect the interlock, check for blown fuses, verify auxiliary contacts, and confirm ground fault or single-phase protections if options are installed. Regular testing of the protective circuitry helps maintain reliable performance in mission-critical applications.
