FAQs
For retrofit applications, plan for bottom feed termination and fusible protection fitting existing switchgear footprints. Ensure enclosure compatibility with NEMA 1, 3R, 4, or 12 ratings, and verify space for the 16 in length, 24 in width, and 32 in height footprint. Consider optional Ground Fault Relay and auxiliary contacts to minimize panel rework.
The unit delivers 1200A amperage at 480V with a 120V control circuit, providing reliable tripping through a bolted pressure contact mechanism. It supports fusion-protected operation and can be integrated with control transformers or existing low-voltage distribution panels to streamline control logic and protect downstream equipment.
Yes. It is UL Listed and compatible with NEMA 1, 3R, 4, and 12 enclosures, enabling installation across indoor and outdoor environments, including damp or dusty locations. This compatibility reduces enclosure substitutions and supports standardization across plant sites.
The primary certification is UL Listed, signifying safety compliance for electrical equipment. The product also supports enclosure protection per common NEMA ratings and offers optional safety features like Ground Fault Relay, Blown Fuse Detection, and auxiliary contacts to enhance monitoring and interlock functionality.
By combining high-current protection, reliable fault tripping, and optional safety features within a single device, the CB1233B120480GAR can reduce downtime and maintenance costs.
