Siemens | MICROMASTER 6SE6400-4BD21-2DA0

Product Details

• Part Number 1 6SE6400-4BD21-2DA0

Product Description

Designed for the MICROMASTER platform, Siemens 6SE6400-4BD21-2DA0 is a Braking Resistor.

Within the control architecture, this product serves the equipment role stated in its description and should be selected by exact model identity rather than by appearance or a broadly similar name. Service decisions should reflect the configured signal and control function.

MICROMASTER provides the platform context for this product, while the AC drives classification identifies its broader automation role. Exact application should follow the installed system configuration. Existing connection and module records should guide replacement work.

For maintenance or replacement work, the exact module designation should be checked against the installed hardware, wiring records, and control-system documentation before the component is placed into service. Its role should remain distinct from that of similarly named assemblies.
