Eaton Specification Sheet - CB3033B120480KAX
High-current capability enables safe interruption of large motor loads, reducing nuisance trips and unplanned downtime in critical lines. This supports reliable protection in switchgear and panelboards used in manufacturing and processing facilities. Bottom-feed, three-pole, fusible design simplifies wiring and fault isolation in crowded panels, enabling faster installation and consistent protection alignment with fuses and circuit-breakers. Interlock with a blow-before-close (BFD) mechanism ensures safety by preventing closing before a successful trip, improving operator safety and equipment protection. This UL Listed device supports multiple NEMA enclosure ratings (1, 3R, 4, 12), delivering equipment compatibility across harsh environments while meeting safety standards. Optional Ground Fault Relay, Blown Fuse Detection, single-phase protection, Kirk provisions, and auxiliary contacts extend diagnostic coverage and protection. The 120V control voltage simplifies integration with standard control circuits and compatible control panels, reducing wiring complexity and commissioning time. Overall, the solution aligns with industry best practices for reliability, maintainability, and regulatory compliance in modern plant environments.

FAQs
For bottom-fed configurations, ensure correct mounting footprint and clearance for three-pole assemblies, plan conduit routing to align with bottom feed terminals, and verify compatibility with auxiliary contacts and optional provisions. Use appropriate fuse blocks and follow manufacturer torque specs to guarantee reliable connections and fault isolation in dense switchgear environments.
CB3033B120480KAX is rated for 3000A with a 480V system voltage and a 120V control voltage. It is a three-pole, fusible, bottom-feed device designed for NEMA 1, 3R, 4, and 12 enclosures, enabling robust protection for large motor and power distribution circuits in industrial settings.
Yes, the CB3033B120480KAX is UL Listed. It supports NEMA enclosure ratings including 1, 3R, 4, and 12, making it suitable for a range of harsh industrial environments and providing safety compliance across often dusty, damp, or corrosive surroundings.
The interlock feature ensures that the switch cannot be closed while a fault or trip condition exists, while the BFD (blow-before-close) mechanism prevents closing unless the circuit has properly tripped. Together, they reduce operator error, protect personnel, and minimize equipment damage in high‑energy, high‑risk applications.
Eaton backs CB3033B120480KAX with a standard warranty of one year from installation or eighteen months from shipment, whichever comes first. For ongoing reliability, consider the optional Ground Fault Relay, Blown Fuse Detection, and auxiliary provisions, and plan periodic inspection of connections and control wiring as part of a preventive maintenance program.
