BSCM Module With Commercial Reference LV434205
Introduction
The BSCM module with commercial reference LV434205 is substituted by the BSCM Modbus SL/ULP module with commercial reference LV434220.
The following table shows the specificities for each BSCM module.
| Characteristics | BSCM module with commercial reference LV434205 | BSCM Modbus SL/ULP module with commercial reference LV434220 |
|---|---|---|
|
Connectivity |
Can communicate via a ULP system |
Can communicate via a ULP system and via a Modbus communication network |
|
NSX cord mandatory |
Yes |
No |
|
SD status availability |
Always available (via NSX cord) |
Available when NSX cord or SD auxiliary contact for BSCM Modbus SL/ULP module is connected |
|
Communication interface required |
IFM or IFE communication interface |
Acts as a communication interface module |
The BSCM Breaker Status Control Module can be used to send the following data via the communication network:
-
Circuit breaker states from OF, SD, and SDE auxiliary contacts
-
Control instructions for the communicating motor mechanism (if present): opening, closing, and resetting
-
Information to assist the operator: storage of the last 10 events
Use the BSCM module with ComPacT NSX DC circuit breakers equipped with thermal-magnetic trip units, and with ComPacT NSX DC switch-disconnectors.
Installation of the BSCM module requires:
-
The NSX cord
-
Pre-installation of the communicating motor mechanism (if present)

The BSCM module cannot be installed at the same time as an OF contact or the SDE contact.
The BSCM module can be installed on site.
For more information about installation, consult the instruction sheet on the Schneider Electric website: GHD16046AA ComPacT NSX DC – BSCM.
Connecting the BSCM Module
To install the BSCM module:
-
Plug in the module.
-
Connect the connectors.
Setting Up the BSCM Module
Setting up the BSCM module on the communication network requires no addressing.

All circuit breakers with BSCM module |
Count of the total number of times the circuit breaker opens and closes (count of OF contact operations). This counter (totalizer) cannot be reset. |
No |
|
Count of the total number of times the circuit breaker opens and closes (count of OF contact operations)(1) |
Yes |

|
|
Count of the number of electrical fault trips by the circuit breaker (count of SDE contact operations)(1) |
Yes |
|
|
Circuit breakers with BSCM module and communicating motor mechanism |
Count of the number of times the communicating motor mechanism opens(1) |
No |
|
Count of the number of times the communicating motor mechanism closes(1) |
Yes |
|
|

Configuring the BSCM Module
To configure the BSCM module, use a PC running EcoStruxure Power Commission software and connected to the USB maintenance interface.
The USB maintenance interface must be connected to the RJ45 connector of a ULP module (for example, IFM Modbus SL communication interface).
With EcoStruxure Power Commission software, you can configure:
-
The maximum number of times the circuit breaker can open and close.
-
The maximum number of times the communicating motor mechanism can close.
-
The reset mode of the communicating motor mechanism.

HAZARD OF REPEATED CLOSING ON ELECTRICAL FAULT
Reconfiguring of the BSCM Breaker
Status Control Module must be done only by qualified electrical personnel.
Failure to follow these instructions can result in injury or equipment damage.
|
The reset mode of the communicating motor mechanism can be configured using the EcoStruxure Power Commission software:
-
Enable Reset even if SDE to authorize resetting of the mechanism using the communication network even after an electrical fault trip.
-
Enable Automatic Reset to authorize automatic resetting after tripping by the MN, MX trip release, or push-to-trip button.
-
Enable Reset even if SDE and Enable Automatic Reset to authorize automatic resetting even after an electrical fault trip.
