FAQs
CB1633T1204806 is designed for compatibility with common industrial switchgear and enclosures rated for NEMA 1, 3R, 4, and 12. It uses top-feed wiring and a fusible protective scheme, enabling straightforward replacement in compatible Eaton and third-party panels without extensive rewiring. Confirm enclosure clearance and bus bar dimensions prior to retrofit.
Key specs include 1600A amperage rating, 120V control voltage, 480V system voltage, and three-pole configuration with fusible protection. These factors determine suitability for high-load feeders, coordination with control circuits, and compliance with your plant’s voltage levels. The charge-before-close mechanism enhances safety during reclosing sequences.
Yes, with UL Listed certification and compatibility with multiple NEMA enclosures (1, 3R, 4, 12), the switch is suited for a range of environments from clean indoor panels to more demanding spaces. The fusible protection and three-pole design support reliable protection in power distribution, motor control centers, and process automation applications.
The product is UL Listed, which supports safety compliance in many regions. Its NEMA ratings (1, 3R, 4, 12) indicate enclosure compatibility. For audits, verify enclosure suitability, ensure correct fuse configuration, and confirm the presence (or absence) of optional features like Ground Fault Relay and auxiliary contacts as required by your control strategy.
The unit’s robust 1600A rating and fusible protection reduce the need for multiple parallel switches, lowering installation costs. The availability of optional features aids fault detection and safer operation, potentially reducing downtime. A one-year warranty from Eaton further mitigates maintenance risk during early use and commissioning.
