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

                    Issue:
                    Where can I buy a Compact NSX breaker?

                    Product Line:
                    Circuit Breakers

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

                    Resolution:
                    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.

                    For support on these breakers, Please see the following link to Global Operations where you can select other Countries:

                    LV432403 / NSX400 - needing handle extended rotary - what is the code?

                    Code = LV432598

                    Micrologic trip unit 320Amp needed for motor protection

                    Use a LV432069

                    What is a 3P 50kA MCCB with 125A trip unit and vigi block, would also need a 125Amp RCBO

                    Use a LV430406 - 160Amp frame + LV430431 125Amp trip unit + LV429211 Vigi module + LV431536 connector = 125Amp RCBO
