Introduction

For system voltages greater than 480 Vac or 480 Vdc, and less than or equal to 690 Vac or 690 Vdc, an insulated variant of the NSX cord must be used, terminated by an electronic module with an RJ45 socket connector. A ULP cord must be used to connect the insulated NSX cord electronic module to a ULP module.

The commercial reference for the insulated NSX cord is LV434204.

The insulated NSX cord electronic module must be supplied with 24 Vdc.

NOTE: The insulated NSX cord cannot be installed in a ComPacT NSX400K circuit breaker.

For more information about installation, consult the instruction sheet on the Schneider Electric website: GHD16313AA ComPacT NSX100–630 – Insulated NSX Cord.
