Insulated NSX Cord

Introduction

For system voltage greater than 480 Vac, an insulated variant of the NSX cord needs to be used, terminated by an electronic module with a female RJ45 connector. A ULP cord must be used to connect the insulated NSX cord electronic module to a ULP module.

The reference for the insulated NSX cord is LV434204.

The insulated NSX cord electronic module must be supplied with 24 Vdc in order to guarantee isolation of the ULP system.

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.

Electronic Module Characteristics

The following table summarizes the electronic module characteristics:

Characteristic	Value
Dimensions	27 x 27 x 27 mm
Mounting	On DIN rail
Degree of protection of the installed module	On the front panel (wall-mounted enclosure): IP40 On the connections (behind the enclosure door): IP20
Operating temperature	-25 to +70 °C
Power supply voltage	24 Vdc -20%/+10% (19.2–26.4 Vdc)
Consumption	Typical: 20 mA/24 Vdc at 20 °C Maximum: 30 mA/19.2 Vdc at 60 °C

Insulated NSX Cord Connection

The NSX cord connects to a ULP module:

IFM or IFE communication interface
FDM121 display
IO module
