Opening, Closing, and Resetting Circuit Breakers With Communicating Motor Mechanism

Introduction

Manage the communicating motor mechanism with the communication network.

For this function, it is necessary to:

Install a Breaker Status Control Module (BSCM) and the NSX cord.
Use a communicating motor mechanism.

Connect the BSCM module to the communication network with the NSX cord:

To receive closing, opening, and reset commands.
To transmit the circuit breaker states: O (OFF), I (ON), Tripped by SDE.

NOTE: The communicating motor mechanism has a specific reference. For more information, refer to LVPED217032EN, ComPact NSX & NSXm Catalogue.

The BSCM module can be configured using EcoStruxure Power Commission software.

The schematic for the communicating motor mechanism in the BSCM module can be configured. It must be created in strict accordance with the simplified motor mechanism schematic.

CAUTION
HAZARD OF REPEATED CLOSING ON ELECTRICAL FAULT Do not modify the wiring diagrams for the motor mechanism. Failure to follow these instructions can result in injury or equipment damage.

Manual Operation: Opening, Closing, and Resetting Locally

The process is the same as the standard motor mechanism.

Automatic Operation: Opening, Closing, and Resetting Remotely

The process is the same as the standard motor mechanism.

Resetting After a Trip on Electrical Fault

Without modifying the factory configuration, the process is the same as for the standard motor mechanism.

Using EcoStruxure Power Commission software to reconfigure resetting of the BSCM module authorizes remote resetting after a trip on electrical fault on a circuit breaker with communicating motor mechanism.
