FAQs
The CB1233T120480KGAX utilizes a top-feed fuse configuration, designed for straightforward wiring in typical switchgear enclosures. It supports three-pole, three-wire setups and is compatible with standard Eaton auxiliary provisions, simplifying integration with existing protection schemes.
Key ratings include 1200 A amperage, 480 V system voltage, and 120 V control voltage, with NEMA 1, 3R, 4, and 12 compatibility. UL Listed certification ensures regulatory compliance. These specifications support safe operation in indoor and outdoor environments depending on enclosure selection.
Interlock and the ground fault detection (BFD) function ensure the switch cannot close while a fault is present and trips promptly when triggered. This reduces accidental closures, minimizes arc-flash risk, and lowers downtime from nuisance trips during maintenance and load changes.
Yes. With a 1200 A rating at 480 V, fusible protection, and rugged construction, it is well-suited for large motors and heavy feeders. The UL certification and NEMA compatibility expand deployment across varied environmental conditions while maintaining protection integrity.
The unit’s robust protection, optional fault-detection features, and modular provisions reduce unplanned downtime and maintenance visits. The result is improved system reliability, safer operation, and a lower total cost of ownership over the equipment lifecycle.
