NSX Cord
Introduction
The NSX cord connects a circuit breaker to the communication network.
The NSX cord can be used:
-
By itself for communicating measurements and settings (only with MicroLogic 5, 6, and 7 trip units)
-
Or with a BSCM module:
-
For communicating measurements and settings (only with MicroLogic 5, 6, and 7 trip units)
-
For communicating states (with standard and advanced trip units)
-

A |
NSX cord microswitch |
State of SD contact |
The NSX cord goes into the SD slot instead of the auxiliary contact. |
B |
Cable equipped with an RJ45 connector for connection to a ULP module. |
Communication network |
Three cable lengths are available: 0.3 m (9.84 ft), 1.3 m (4.27 ft), and 3 m (14.7 ft). |
C |
Internal link to the MicroLogic 5, 6, or 7 trip unit or the BSCM module |
Communication network |
With the BSCM module, the NSX cord also transmits the circuit breaker states. |
The NSX cord also provides the 24 Vdc power supply:
-
For the MicroLogic 5, 6, or 7 trip unit (without BSCM module)
-
For the BSCM module (when this module is installed)
Installation
The slots used to install the NSX cord depend on the circuit breaker type.

The NSX cord cannot be installed at the same time as the SD contact.
The NSX cord can be installed on site.
For more information about installation, consult the instruction sheet on the Schneider Electric website: GHD16047AA ComPact NSX100–630 – NSX Cord.
Communication with the NSX Cord
The NSX cord connects to the following ULP modules:
-
IFM or IFE communication interface
-
FDM121 display
-
IO module
