Power Line Filter Modules Procurement Notes

Verify the specific suffix designation when ordering, as variants such as ESP-03-221-D exist within the same family. Confirm that the chassis mounting requirement aligns with the target enclosure design. Ensure the application voltage does not exceed the 250 VAC or 250 VDC ratings. Cross-reference the screwless termination type with existing wiring infrastructure to guarantee compatibility during assembly.

Power Line Filter Modules Selection Notes

Select this model for applications requiring low leakage current and compact single-phase filtering. The screwless terminals simplify assembly processes compared to traditional screw-type connections. Consider the chassis mount form factor when evaluating spatial constraints within the equipment housing. Verify that the 3 A current rating meets the maximum load requirements of the protected circuit.
