New enhanced Breaker Status and Communication Module

June 2025 Electrical Power & Protection

Schneider Electric has launched its new Breaker Status and Communication Module (BSCM) Modbus SL/ULP which delivers enhanced performance, improved connectivity and simplified integration for power distribution systems. The new BSCM is a direct replacement for the legacy BSCM (LV434205). It offers full backward compatibility, including continued support for the existing Universal Logic Plug (ULP) architecture. The new BSCM makes it easier for users to implement digital monitoring and control into their Schneider Electric ComPacT NSX circuit breakers. It offers plug-and-play installation, flexible communication modes and greater system sustainability.


Key features and benefits of the new BSCM include:

Dual communication modes: Modbus Serial Line (SL) and Universal Logic Plug (ULP) offer users the flexibility to integrate with either legacy or modern systems.

Simple plug-and-play topology: With an RJ45 interface and simplified wiring, installation time is significantly reduced, making the solution more accessible and cost-effective.

Native Modbus SL communication: This is directly from the ComPacT NSX breaker, eliminating the need for additional digital blocks.

Rotary switch on the BSCM: This allows for easy setting of Modbus addresses without additional configuration tools.

Enhanced control and monitoring in Modbus SL mode: The module supports advanced features via IFE version 5.x, including web pages, time stamping, alarm management and motor mechanism control – adding value over legacy power and system (PaS) tools.

Firmware upgrades and diagnostics: Future ready with support for firmware updates and secure diagnostics, ensuring long-term reliability and adaptability.

Sustainable and efficient: By reducing the number of digital modules required per installation the BSCM supports a more streamlined, environmentally conscious infrastructure.


The BSCM is ideal for panel builders, OEMs and facility managers seeking a simplified, future-proof solution that maintains continuity with existing systems while unlocking new digital capabilities.
