Procurement Notes

Verify the specific voltage rating and phase configuration against system requirements before procurement. Confirm that the quick-connect terminal type matches existing cable harnesses or busbar arrangements. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Selection Notes

Select this model when a single-stage solution is sufficient for the required attenuation levels. Consider the 20 A current rating to ensure adequate capacity for the load. Evaluate the physical dimensions to confirm fit within the designated enclosure space. Verify compatibility with the system's input frequency range of DC to 400 Hz.

Part Context

This component belongs to the FN355 series of standard performance filters from Schaffner. The series offers various configurations for different current and voltage applications. The FN355-20-06 specifically addresses three-phase Wye systems requiring moderate current handling capabilities.

Replacement Considerations

Check for direct substitutes within the FN355 series with matching current ratings. Verify equivalent electrical specifications if considering alternative manufacturers. Ensure mechanical mounting and terminal types are compatible with existing infrastructure.
