Eaton Specification Sheet - CB2533B120208AXCT
2500A amperage rating provides robust current interruption for heavy main feeders, reducing fault exposure and enabling safe shut-off in demanding power distribution setups. Applications include large switchgear banks and motor control centers where downtime costs are critical; the result is faster response to faults and minimized production losses. The device’s 208 V system compatibility with 120 V control voltages simplifies control wiring, cuts panel depth, and streamlines schematics, delivering installation time savings and improved maintainability. NEMA 1, 3R, 4, and 12 ratings indicate suitability for varied environments, while bottom-feed and fusible protection reduce wiring complexity and ensure dependable isolation. Optional Ground Fault Relay, blown fuse detection, auxiliary contacts, and Kirk provisions provide flexible protection architectures that meet industry standards and customer-specific interlock requirements. UL Listed certification reinforces compliance in regulated facilities, supporting audits, insurance requirements, and long-term reliability in industrial power applications.

FAQs
The CB2533B120208AXCT is designed for bottom-feed wiring, simplifying enclosure entry and reducing panel depth. Ensure the three-pole, three-wire connections match the 208 V system, and verify the 120 V control circuit is isolated from main power. Use proper torque on lugs per the Eaton specification and install optional Ground Fault Relay or auxiliary contacts only after confirming enclosure suitability and clearances. Document interconnection diagrams for maintenance and audits.
With a 2500A amperage rating, the switch delivers rapid, controlled tripping under fault conditions, minimizing arc duration and electrical stress. The fuse configuration is designed to provide reliable protection, and the three-pole, three-wire arrangement ensures balanced fault clearing across phases. The unit supports 208 V system voltage and 120 V control voltage, enabling robust control logic while maintaining strong main circuit protection in large panels.
Ideal for industrial power distribution, motor control centers, and large switchgear assemblies where high current interruption and reliable tripping are essential. Its NEMA ratings (1, 3R, 4, 12) make it viable in indoor, outdoor, and rugged environments. Optional features like Ground Fault Relay and auxiliary contacts support customized protection schemes for manufacturing, facility automation, and data-center infrastructure.
UL Listed certification accompanies the CB2533B120208AXCT, signaling compliance with electrical safety and performance standards critical for regulated facilities. This certification assists with safety audits, insurance requirements, and warranty acceptance. The device’s compatibility with common industrial voltages (208 V system, 120 V control) also aligns with many regulatory and utility guidelines for panel construction.
Optional Ground Fault Relay, blown fuse detection, and auxiliary contact provisions enable tailored protection without redesigning panels, reducing maintenance complexity and downtime. While these options add initial cost, they improve fault diagnosis, improve safety compliance, and shorten mean time to repair, delivering a favorable return on investment through reduced outages and streamlined serviceability.
