Eaton Specification Sheet - CB1633B120480GPAXC
Electrical trip with a charge-before-close mechanism helps prevent arcing and ensures a controlled, safe opening of the circuit. This reduces contact wear and improves protection reliability for main feeders and motor circuits in demanding industrial environments. Application: ideal for power distribution panels and switchgear in manufacturing and processing facilities. High amperage rating of 1600A and system voltage of 480V support large loads with fewer devices, reducing panel complexity and maintenance. This consolidates protection in a single unit for heavy-duty feeders in steel, chemical, and cement plants. Control voltage of 120V enables straightforward integration with common control circuits, while fusible protection delivers fast, selective disconnection. This combination supports safer operation in harsh environments and simplifies compliance with industrial standards. Bottom-feed configuration and bottom fuse arrangement simplify wiring in existing switchgear and enable easier installation, reducing field labor and downtime. The unit’s 200 lb weight and robust enclosure compatibility ensure stable mounting and reliable service in factory floors. Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Auxiliary Contact Provisions, and Kirk provisions provide scalable protection and diagnostic capabilities, minimizing unplanned outages. Warranty is Eaton Selling Policy 25-000 (one year from installation or 18 months from shipment), aligning with reliability expectations for critical electrical assets.
