FAQs
Install the CB1233T120480KA95 with a top-feed configuration in a three-pole panel, ensuring the 1NO-1NC contacts align with the wiring plan. Verify 480 V system connections and 120 V control voltage compatibility with the control circuit. Consider optional auxiliary contacts and ground fault provisions to enhance diagnostics. Handle the unit's 180 lb weight with proper lifting equipment and follow manufacturer torque specs for terminal connections.
Key ratings include 1200A amperage, 120 V control voltage, and 480 V system voltage, with fusible protection and UL Listed certification. It uses a three-pole configuration with 1NO-1NC contacts and top-feed/fuse arrangement for straightforward installation. The device supports NEMA 1, 3R, 4, 12 environments, making it suitable for demanding industrial settings.
Yes. The CB1233T120480KA95 is designed for high-current protection in MCCs and switchgear, featuring a robust three-pole, 1NO-1NC configuration and a trip-before-close mechanism. Its top-feed design simplifies panel wiring, while fusible protection and BFD with status lights help prevent unscheduled downtime in motor-driven processes.
The CB1233T120480KA95 is UL Listed and offers compatibility with NEMA ratings 1, 3R, 4, and 12.
