Eaton Specification Sheet - CB1633T120208G
High-current protection with 1600A amperage rating and fusible protection reduces the risk of arc flash and nuisance trips, translating to fewer shutdowns and more predictable maintenance windows. This feature set supports more reliable protection coordination in feeders and motor control applications, enabling safer startup sequences and reduced downtime in large industrial panels. The top-feed fuse configuration and ground fault with control power transformer streamline installation, minimize wiring runs, and enhance fault detection accuracy in demanding environments. With NEMA 1, 3R, 4, and 12 compatibility, the CB1633T120208G fits a broad range of indoor and outdoor enclosures, delivering versatile installation without compromising protection. The three-pole, three-wire design simplifies wiring schemes and improves fault clearing times, which is crucial for critical processes in manufacturing and processing facilities. Optional features like Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions expand protection coverage for complex electro-mechanical systems. A one-year warranty from installation or eighteen months from shipment provides reassurance for procurement teams and operational managers, helping to manage total cost of ownership across asset lifecycles.

FAQs
CB1633T120208G is designed for top-feed mounting with a three-pole, three-wire configuration. Ensure the enclosure supports NEMA ratings 1, 3R, 4, or 12, connect the 120 V control voltage to the control power transformer, and route conductors to the three poles with fusible protection as specified. Use the ground fault option if available and verify wiring continuity before energizing to prevent mis-tripping and ensure safe startup.
Key specs include 1600A amperage rating, 208 V system voltage, 120 V control voltage, and fusible protection. The three-pole, three-wire design supports coordinated breaker and fuse protection, while the ground fault with control power transformer improves fault detection. These features collectively reduce downtime, improve startup reliability, and enable precise protection sequencing in large feeders.
Yes, with NEMA ratings 1, 3R, 4, and 12, CB1633T120208G offers versatile enclosure compatibility for indoor and outdoor installations. The fusible protection and top-feed configuration are well-suited for industrial environments with demanding uptime requirements, such as manufacturing lines, processing plants, and utility switchgear where reliable high-current switching and fault protection are essential.
CB1633T120208G is UL Listed, providing recognized safety certification for electrical devices in the U.S. and Canada. This certification simplifies regulatory approvals for installations in regulated facilities and supports conformity with safety programs. The combination of UL listing with broad NEMA ratings further reinforces protective performance in diverse enclosure conditions.
By coordinating high-current protection with reliable fault detection (including optional ground fault and fuse monitoring), this switch reduces unplanned downtime and accelerates fault diagnosis. The built-in protection features and robust enclosure compatibility lower replacement and service costs, while the warranty provides risk mitigation for asset-intensive facilities, contributing to a lower total cost of ownership over the asset life.
