FAQs
CB1233B120480 is designed for high-current protection in industrial power-distribution and motor-control centers. It supports three-pole, fusible protection with bottom feed and accommodates 480 V systems, making it ideal for large feeders in panel-mounted switchgear. Its UL Listed status and NEMA compatibility ensure safe operation within standard industrial enclosures, while optional provisions simplify integration into existing control architectures.
The optional ground fault relay provides leakage sensing to prevent line-to-ground faults from causing damage, while blown fuse detection immediately identifies fuse impairments before progressing to fault conditions. Together, they improve safety and reliability, reduce unscheduled downtime, and help meet regulatory safety requirements in critical production lines and energy-intensive facilities.
Yes. The catalog notes indicate availability of single-phase protection and auxiliary contact provisions, which allow the switch to be configured for selective phase protection and extended control/monitoring capabilities. This compatibility supports integration with modern control schemes and diagnostic practices, helping engineers tailor protection to specific process or equipment needs.
The unit presents a footprint of 16.5 in depth, 24 in width, and 32 in height with an approximate weight of 200 lb. It is designed for bottom-fed, three-pole, fusible configurations and should be mounted in a suitable enclosure or panel with adequate clearance for service access, ventilation, and wiring harness routing to ensure reliable operation and maintenance.
Eaton provides a one-year warranty from installation or an eighteen-month period from shipment, whichever occurs first. Support includes the Eaton Selling Policy 25-000 guidance and access to specification sheets, catalogs, and technical resources. This helps ensure timely maintenance planning, parts availability, and continued performance of protective switching equipment.
