Procurement Notes

Verify the specific datasheet version for the NBH-20-221 to confirm compliance certifications such as UL, CSA, DIN, VDE, or ENEC. Ensure the application voltage does not exceed 250 VAC or 250 VDC. Confirm that the load current remains within the 20 A limit. Check for any required ordering suffixes if alternative mounting styles are needed.

Selection Notes

Select this model when a two-stage filter is required for single-phase applications. Ensure the chassis mounting style fits the enclosure design. Verify that the 20 A current rating meets the system requirements. Consider the weight and dimensions for mechanical integration. Compare leakage current specifications if safety isolation is critical.
