FAQs
Verify that the panel enclosure supports a three-pole, bottom-feed configuration and that the system voltage is 208 V with a 120 V control circuit. Confirm UL Listed compatibility and ensure space for the bottom fuse arrangement and SPVR device. Check that the existing equipment can accommodate optional Ground Fault Relay or Auxiliary Contacts if needed.
Key ratings include 1600A amperage, 208V system voltage, 120V control voltage, and a fusible protection scheme. The device employs an electrical trip with a capacitor trip device (SPVR) and provides three-pole, three-wire protection. It is UL Listed and compatible with select NEMA enclosures for safe, code-compliant operation.
Yes. The three-pole, 208V-rated switch is designed for heavy-duty motor protection in control panels and switchgear. Its SPVR device reduces nuisance trips, and the UL Listed certification supports industrial compliance. The bottom feed and fuse configuration simplify integration into compact MCCs and large switchgear assemblies alike.
CB1633B120208RA9 is UL Listed, with compatibility to multiple NEMA enclosure ratings (NEMA 1, 3R, 4, 12). This combination supports safe installation in manufacturing and process environments. Optional features such as Ground Fault Relay and Blown Fuse Detection further enhance protection compliance and diagnostic capabilities.
The capacitor trip device (SPVR) and three-on-light signaling provide clear, reliable fault status, reducing downtime and maintenance time. Optional accessories enable extended protection coverage without replacing the base unit. The UL Listed rating and sturdy three-pole construction contribute to long-term reliability and a favorable total cost of ownership in demanding industrial settings.
