FAQs
When installing CB2533B120480AX5, ensure compatibility with bottom-feed wiring and proper enclosure space for a 17 in length, 28 in width, and 32 in height unit weighing 235 lb. Plan for three-pole, 1NO-1NC operation with fusible protection and 120V control. Verify UL Listed compliance and allow for optional accessories such as ground fault relays and auxiliary contacts during panel design.
The switch provides a 2500A amperage rating at 480V with a 480V system voltage and a 120V control circuit. Its 1NO-1NC contact configuration and fusible protection enable robust interrupt capability in high-current circuits. Use in motor control centers and distribution panels to improve overload protection while meeting NEMA-rated enclosure requirements.
Yes. With its three-pole, 1NO-1NC configuration and bottom-feed design, CB2533B120480AX5 is well-suited for motor control centers and switchboards handling large loads. The UL Listed rating and NEMA compatibility (1, 3R, 4, 12) support safe operation in varied environments, while optional protections (ground fault, blown fuse detection) enhance reliability in complex systems.
CB2533B120480AX5 carries UL Listed certification, signaling compliance with recognized safety standards for electrical equipment. This certification supports market acceptance and regulatory alignment in North America. The unit also aligns with NEMA enclosure ratings (1, 3R, 4, 12), aiding installation in diverse industrial environments while maintaining protection for high-current, fusible applications.
To maximize ROI, consider adding Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions. These options expand fault detection, control interlocks, and integration with control systems, reducing downtime and improving safety. Also leverage Eaton’s specification sheet and warranty terms to plan lifecycle costs and maintenance planning.
