Procurement Notes

Verify the specific datasheet version to confirm terminal type compatibility and thermal derating curves. Ensure the application environment meets the specified voltage and current ratings. Check for REACH SVHC compliance status relevant to your region before finalizing procurement specifications.

Selection Notes

Select this model when space-constrained DIN rail installation is required for single-phase AC lines. The integrated PE choke simplifies design by reducing external component count. Confirm that the 6 A rating aligns with the maximum load current and inrush requirements of the downstream equipment.

Part Context

This component belongs to the FMAB NEO series, which focuses on compact power line filtering solutions. It serves as an alternative to discrete filter assemblies, offering standardized DIN rail mounting for easier system integration and maintenance in industrial and commercial electronic applications.

Replacement Considerations

Consult official Schurter documentation for direct cross-references. Verify electrical parameters such as attenuation characteristics and physical dimensions against potential substitutes to ensure functional equivalence.
