Eaton Specification Sheet - CB2033T120480G5
High current capability and voltage ratings translate to tangible business outcomes, enabling reliable main distribution switching for heavy-duty equipment with up to 2000A and 480V system voltage. The 120V control voltage, plus a 1 NO-1 NC contact configuration in a robust three-pole package, supports efficient interlocking and rapid fault isolation in control circuits and power feeds. Top-feed wiring and the integrated control power transformer simplify panel layout, reducing installation time and wiring errors while improving enclosure density in compact switchgear. Fusible protection provides defined fault isolation, lowering the risk of cascading failures and facilitating faster maintenance actions. UL Listing and NEMA compatibility (1, 3R, 4, 12) boost regulatory confidence and applicability in demanding environments, from manufacturing floors to data-centre peripherals. Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary/ Kirk provisions address specialized protection schemes without redesigning the system. The three-wire, three-pole configuration supports straightforward replacement and spare parts compatibility, minimizing downtime during maintenance windows.

FAQs
The CB2033T120480G5 uses a top-feed configuration and supports a 3-wire, three-pole setup with 1 NO-1 NC contacts. It accepts up to 2000A at 480V and is designed for straightforward integration into standard control circuits, aided by the built‑in control power transformer. Ensure wiring follows OEM enclosure guidelines and SMT/Gland entries and use the ground fault or auxiliary provisions only if your protection scheme requires them.
Key specs include an amperage rating of 2000A, system voltage of 480V, and control voltage of 120V. The device features a 1 NO-1 NC contact configuration in a three-pole arrangement, with fusible protection to isolate faults. These ratings make it suitable for high‑power distribution roles and safety interlocks in industrial settings.
Yes. The unit is UL Listed and compatible with NEMA enclosures: 1, 3R, 4, and 12, which supports operation in a variety of harsh industrial environments. The top-feed, rugged bolted design plus fusible protection reduces exposure to dust, moisture, and mechanical stresses, helping maintain reliability in manufacturing and processing facilities.
The CB2033T120480G5 carries UL Listed certification, signaling conformance to recognized safety standards. It is designed for rugged industrial use and supports protection schemes such as ground fault relay options and auxiliary provisions. The warranty aligns with Eaton’s policy, offering one year from installation or 18 months from shipment, whichever occurs first.
The integrated control transformer, fusible protection, and high-current capability reduce downtime by enabling quicker fault isolation and safer power-down. With optional ground fault and auxiliary provisions, you can tailor protection to your process, potentially lowering maintenance costs and extending service life of downstream equipment. The robust NEMA compatibility helps avoid enclosure-related retrofits, delivering a favorable total cost of ownership over the equipment lifecycle.
