Eaton Specification Sheet - CB2033B120480G
High amperage and rugged protection translate to tangible business outcomes: 2000A protection at 480V with a 120V control circuit reduces the risk of cascading faults in large feeders, enabling safer startup sequences and quicker fault isolation in manufacturing lines. The three-pole, bottom-feed configuration simplifies mounting in tight control panels and reduces wiring complexity, delivering faster commissioning and improved space utilization across distribution centers. The electrical trip with charge-before-close mechanism minimizes arcing during switching, extending contact life and improving uptime in heavy-duty applications such as presses and conveyors. Optional Ground Fault Relay, Blown Fuse Detection, and Single Phase Protection enable tailored protection schemes, boosting compliance with safety standards and reducing unplanned outages. The UL Listed certification and robust enclosure support operation in demanding environments, while the compact 16 x 24 x 32 inch footprint and 200 lb weight aid planning for retrofits and new installations alike.

FAQs
Yes. The CB2033B120480G is specified for bottom-feed wiring and three-pole operation, making it compatible with typical 480V feeder panels. The built-in control power transformer simplifies control wiring, and its compact 16 in by 24 in by 32 in enclosure facilitates retrofit into space-constrained panels while preserving protective coordination with fusible protection.
This device is rated for 2000A at 480V with a 120V control circuit. It uses fusible protection and supports NEMA 1, 3R, 4, and 12 environments. The three-pole, three-wire design and charge-before-close mechanism enhance safe switching and fault containment in large industrial feeders.
Yes, thanks to its NEMA ratings (1, 3R, 4, 12) which cover indoor and many outdoor or wash-down environments. UL Listed certification further ensures compliance with safety standards. For outdoor installations, verify enclosure level and mounting to maintain protection against dust, moisture, and incidental wash-downs.
Options include Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Auxiliary Contact Provisions, and Kirk Provisions. These enable tailored protection schemes, improved fault diagnosis, and easier integration with downstream protective devices, reducing downtime and supporting regulatory compliance in complex power-distribution schemes.
Eaton provides a warranty per policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This aligns with typical industrial equipment expectations and supports ROI through predictable service life, with access to Eaton support and replacement parts if protective components fail under normal use.
