          Will the Compact NSX breaker be for sale in the USA or Canada?

          Where can I buy a Compact NSX breaker?

          Product Line:
          Circuit Breakers

          This breaker is popular overseas and there is interest in the US

          There are no plans for a general release of the Compact NSX breaker line in North America, since the NSX is not UL Listed to UL489. (UL 489 is the standard commonly required in the US.) In the US, the Powerpact Circuit Breakers should be used (Powerpact breakers are UL, CSA and IEC-rated).

          If an existing piece of equipment has an NSX breaker which needs replacing, we have made a few catalog numbers available for sale in the US. The list of numbers will vary based upon need. Contact your local authorized Schneider Electric distributor for assistance on your specific NSX catalog number.
