Power Line Filter Modules Procurement Notes

Verify the specific datasheet version for the NAM-04-331-D to confirm compliance with RoHS3 standards. Ensure that the required operating voltage does not exceed 250 VAC or 250 VDC. Confirm that the circuit current remains within the 4 A limit. Check that the installation environment supports DIN rail mounting and that screw termination tools are available for assembly.

Power Line Filter Modules Selection Notes

Select this model when a single-phase filter with a 4 A capacity is required. The 330 pF capacitance value determines the attenuation characteristics in the 10 kHz to 10 MHz range. Consider the DIN rail form factor for space-constrained enclosures. Verify that the leakage current specification meets safety requirements for the intended application.

Power Line Filter Modules Part Context

This component belongs to the NAM series of power line filter modules from Cosel USA, Inc. The series offers various current ratings and capacitance values.
