FAQs
CB1233T120480GRA9 is designed for top-feed, three-pole configurations with fusible protection and can be installed in standard electrical rooms or retrofit into compatible Eaton switchgear. The unit supports NEMA-rated enclosures up to 1, 3R, 4, 12, aligning with industrial facility requirements. Verify clearance and mounting provisions per the Eaton datasheet before procurement.
Key specs include a 1200A amperage rating, 480V system voltage, 480V maximum voltage, and three poles (three-wire). Control voltage is 120V, with a top-feed fuse configuration. The device features SPVR with capacitor trip and a ground-fault option, making it suitable for high-current switchgear and MCC applications.
Yes. With a three-pole, fusible design and UL Listed certification, CB1233T120480GRA9 is engineered for reliability in industrial switchgear and MCCs. Its NEMA-rated enclosure compatibility (1, 3R, 4, 12) and top-feed configuration support operation in demanding environments, while optional features like ground-fault and auxiliary provisions enable robust protection strategies.
The product carries UL Listed certification, indicating safety compliance for electrical equipment. It also aligns with NEMA enclosure ratings (1, 3R, 4, 12) for environmental suitability. Optional accessories (Ground Fault Relay, Blown Fuse Detection, Auxiliary Contacts) support enhanced protection schemes while maintaining regulatory alignment for industrial distribution equipment.
The combination of a 1200A rating, rapid capacitor-trip SPVR, and ground-fault protection reduces unplanned downtime by speeding fault isolation and minimizing exposure to fault conditions. UL Listed safety and rugged NEMA compatibility lower maintenance costs over time, while modular options for auxiliary signaling support longer service intervals and easier preventive maintenance planning.
