• DIN rail mounted power distribution systems

Power Line Filter Modules Procurement Notes

Verify the specific ordering suffix to confirm the mounting configuration and terminal type. Ensure the input voltage and current requirements align with the 250 VAC/VDC and 20 A ratings. Confirm compliance with relevant regional safety standards before integration into final assemblies.

Power Line Filter Modules Selection Notes

Select this model for applications requiring single-stage common mode filtering on DIN rails. Compare against chassis-mounted variants if space constraints differ. Verify that the 220 pF capacitance meets system leakage current limits. Ensure the screw terminal interface matches existing wiring infrastructure.

Power Line Filter Modules Part Context

This component belongs to the NAP series of power line filters from Cosel. The series offers various current ratings and mounting options. The NAP-20-221-D specifically addresses mid-range current needs with DIN rail compatibility, distinguishing it from higher-capacity or chassis-mount alternatives within the same product family.

Power Line Filter Modules Replacement Considerations

Check for direct substitutes within the NAP series with different current ratings or mounting styles. Verify pinout and dimensional compatibility when considering alternative manufacturers' DIN rail filters.
