FAQs
Begin by confirming the panel enclosure supports a three-pole, 1NO-1NC configuration and top-feed wiring. Mount the CB1633T120480P5C securely, connect the three incoming lines to the appropriate terminals, and wire the 120V control circuit per the diagram. Verify fusible protection is configured as specified and that the capacitor trip device is correctly placed to assure fast operation.
Key specs include 1600A amperage rating, 480V system voltage, 120V control voltage, single-phase protection with capacitor trip device, and 1NO-1NC contact configuration across three poles. These values enable protection for high-current motors, ensure reliable trip coordination, and support straightforward integration into 480V electrical systems with a 120V control circuit.
Yes. The device carries UL Listing and is compatible with NEMA ratings 1, 3R, 4, and 12, providing robust protection for indoor and outdoor installations. The top-feed, fusible design and capacitor trip device enhance reliability, while enclosure compatibility reduces the need for additional protective enclosures in challenging industrial environments.
The CB1633T120480P5C is UL Listed, with NEMA-rated enclosures supporting safe operation in diverse environments. Optional features include Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact Provisions, which improve diagnostic capabilities, signaling, and expandability without major rework to the main protection scheme.
The device footprint corresponds to a 16 in length, 24 in width, and 28 in height package, with an approximate weight of 180 lb. Plan for vertical clearance, lifting capabilities, and panel cutouts to accommodate these dimensions, ensuring safe handling during installation and future maintenance activities.
