Eaton Specification Sheet - CB2033B120480K7
High-current capacity and a 2NO-2NC contact configuration deliver robust protection for heavy loads. With a 2000A amperage rating and a 120 V control voltage alongside a 480 V system rating, it coordinates safely with downstream protective devices while enabling compact, single-device panels. An interlock feature and fusible protection improve safety and regulatory compliance, ensuring safe sequence control and predictable disconnection. The bottom feed design simplifies wiring layouts, reduces the risk of mis-wiring, and supports clean enclosure strategies in switchgear and motor-control centers. Flexible installation options are enhanced by three-wire, three-pole alignment and no ground fault; catalog notes indicate optional Ground Fault Relay, Blown Fuse Detection, and auxiliary contact provisions for tailored protection without extra components. The UL Listed certification and NEMA ratings support installation in harsh environments, and the footprint plus weight information informs enclosure sizing, mounting, and service access, accelerating project timelines and reducing field modification time. From a maintenance and ROI perspective, consolidating interlock, protection, and contact arrays into a single device reduces spare parts and downtime while simplifying ongoing servicing and testing.

FAQs
CB2033B120480K7 is designed for bottom-feed, three-pole, 3-wire installations, with 2 NO-2 NC contacts. This configuration supports safe, organized wiring and enables straightforward integration with downstream protection devices. The bottom-feed layout simplifies cable entry and provides reliable mechanical alignment in chassis or enclosures, reducing field modification time and potential connection errors.
The switch offers a 2000 A amperage rating, 120 V control voltage, and a 480 V system voltage with fusible protection. It is UL Listed and compatible with NEMA enclosures including 1, 3R, 4, and 12. This combination ensures robust overload protection, predictable trip performance, and regulatory compliance for industrial control installations.
Yes. Interlock is an integral feature for preventing unsafe re-energization after faults, and optional ground fault relay and auxiliary contact provisions support broader protection schemes. The device’s no ground fault configuration helps maintain electrical safety in environments where grounding paths must be carefully managed.
The CB2033B120480K7 carries UL Listed certification and is backed by Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. With NEMA ratings and optional protections such as blown fuse detection and single-phase protection, this product aligns with standard safety programs and service strategies.
Plan for a bottom-feed, three-pole installation with a 16 in L x 24 in W x 32 in H footprint and a 190 lb weight. Ensure enclosure space accommodates the 2000 A main path and wiring clearances; confirm 120 V control circuitry and 480 V system requirements. Consider optional Ground Fault Relay and auxiliary contacts for future expansion; verify compatibility with Eaton devices.
