Siemens Selectivity Module for use with SITOP, SITop Series

Siemens SITop Series Selectivity Module, Selectivity Module Accessory, RoHS Compliant - 6EP1961-2BA51

This selectivity module provides targeted selective protection for SITOP power systems within industrial control environments. It functions as an accessory to enhance coordination between power-supply outputs and downstream protection, helping to manage fault isolation and maintain continuity of critical loads. The unit is manufactured by Siemens and conforms to RoHS requirements, making it suitable for integration where restricted-substance compliance is required.

Features and Benefits:

• Designed for integration with SITOP units for coordinated protection
  RoHS-compliant construction reduces restricted-substance exposure
  Compact format supports space-constrained control panels
  Concentrated solution reduces component footprint and complexity
  Energy-saving behaviour supports efficient power distribution

Applications

• Suitable for selective fault isolation in automation power supplies
  Ideal for protecting control circuits in electronic assemblies
  Used with SITOP power supplies in electrical distribution racks
  Can be used for maintaining uptime in mechanical plant controls

How does it assist with power distribution coordination?

It acts as a selectivity accessory that enables staged fault clearance between the supply and downstream circuits, helping to isolate faults without interrupting entire systems.

Is the unit appropriate for installations with environmental restrictions on materials?

Yes, the product meets RoHS criteria, indicating components comply with restrictions on specific hazardous substances for regulated installations.

What functional benefit does the Compact form provide in panel design?

The Compact configuration reduces required panel space and allows denser assembly of control components, simplifying wiring routes and enclosure layout.

Which manufacturers supply this accessory and how is it designated?

The accessory is produced by Siemens and is provided as a selectivity module intended for use with SITOP power supplies.
