Eaton Specification Sheet - CB2033B120480AR
Feature → Business Impact → Application: The CB2033B120480AR delivers high-current protection up to 2000 A at 480 V, enabling compact, economical protection blocks in large switchgear while reducing panel footprint and wiring complexity. This directly lowers installation costs and improves fault-clearance speed in motor control centers (MCCs). Application-wise, engineers can rely on a robust three-pole, three-wire configuration for reliable door interlock and coordinated protection in industrial feeders. Feature → Business Impact → Application: Bottom feed and fusible protection provide a straightforward protection scheme with clear fault isolation, minimizing arc-flash exposure during maintenance and enabling safer hot-wiring practices within panel interiors. This suits retrofit projects and new builds where space is constrained and compliance is critical. Feature → Business Impact → Application: The three-pole, charge-before-close mechanism offers rapid, controlled tripping with reduced crank-down time, improving system uptime and enabling predictable maintenance windows in high-demand facilities like food and beverage, metals, and chemical processing. Feature → Business Impact → Application: Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact Provisions extend configurability without requiring separate modules, lowering total cost of ownership and simplifying integration with PLCs, SCADA, and protection schemes. Feature → Business Impact → Application: UL Listed and NEMA-rated compatibility (1, 3R, 4, 12) ensure compliance with global electrical codes and reliability standards, smoothing procurement cycles and reducing regulatory risk in multi-site deployments. Feature → Business Impact → Application: Heavy-duty construction (190 lb, 16 in depth, 32 in height, 24 in width) supports rugged industrial environments, with Eaton’s warranty policy providing post-install support and predictable replacement cycles, aiding long-term budgeting and lifecycle planning.

FAQs
Bottom-feed installation requires planning for panel cutouts that accommodate a 16 inch depth, 24 inch width, and a 32 inch tall unit. Ensure the enclosure supports three-pole, three-wire wiring and accommodates a 190 pound assembly. Consider optional provisions such as auxiliary contacts and Kirk provisions to align with internal interlocks. Secure mounting hardware and verify 480 V power is routed to the three poles with correct phasing to prevent mis-trips.
The CB2033B120480AR provides a 2000 A amperage rating with 480 V system voltage and fusible protection, enabling rapid isolation of faults in demanding power distributions. The charge-before-close mechanism ensures controlled tripping, while the three-pole, three-wire configuration supports reliable fault clearance in large panels. This combination minimizes fault energy transfer and reduces maintenance delays after tripping events.
Yes. The catalog notes indicate availability of optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, and Auxiliary Contact Provisions. These options can be integrated to enhance protection coverage, enable detailed fault diagnostics, and support integration with PLCs and protection relays without requiring major panel rewiring.
CB2033B120480AR is UL Listed and compatible with multiple NEMA enclosure ratings, including NEMA 1, 3R, 4, and 12. These certifications help ensure code compliance, safe operation in diverse environments, and smoother acceptance across electrical jurisdictions, simplifying procurement and reducing risk in multi-site deployments.
Using CB2033B120480AR can lower total cost of ownership by reducing nuisance trips, speeding fault isolation, and simplifying maintenance with optional diagnostics features. Its high current rating and robust construction support longer service intervals, fewer spare parts, and easier sourcing of genuine Eaton components, translating into measurable uptime gains and predictable lifecycle budgeting.
