It features a 50 A current rating and operates at voltages up to 277 VAC or 250 VDC. The unit utilizes screw terminal connections for secure wiring. Key electrical specifications include a leakage current of 10 µA and an internal capacitance of 4.7 nF. It complies with UL, CSA, DIN, VDE, and ENEC standards, ensuring safety for industrial applications.

Power Line Filter Modules Feature Summary

• Single-stage attenuation design for effective common mode noise suppression
• Dual-mounting capability supporting both chassis and DIN rail installation methods
• Comprehensive international safety certifications including UL, CSA, VDE, and ENEC

Power Line Filter Modules Applications

• Industrial machinery control panels requiring EMC compliance
• Power distribution units in commercial building infrastructure
• Electronic equipment housings needing single-phase line filtering

Power Line Filter Modules Procurement Notes

Verify the specific voltage rating (250 VDC vs 277 VAC) required for your application against the datasheet. Confirm that the 10 µA leakage current meets safety isolation requirements. Ensure the mounting style matches your enclosure design, as this model supports both chassis and DIN rail configurations. Check terminal type compatibility before integration.

Power Line Filter Modules Selection Notes

Select this component when a single-stage filter is sufficient for noise reduction needs. The 50 A rating suits high-current single-phase loads. Consider the 10 µA leakage current limit if personnel safety isolation is critical. Verify that the physical dimensions fit the available space for either chassis or DIN rail mounting options.

Power Line Filter Modules Part Context

This part belongs to the COSEL NAP series of EMI filters. The series offers various current ratings and capacitance values to suit different power levels. The NAP-50-472 specifically addresses mid-range current applications with moderate noise attenuation requirements. It shares the same form factor and mounting principles as other models in the NAP family.

Power Line Filter Modules Replacement Considerations

Direct substitutes within the NAP series include NAP-50-222, NAP-50-223, and NAP-50-683. These alternatives share identical mechanical dimensions and mounting styles but differ in capacitance and resulting attenuation characteristics. Verify that the alternative capacitance value aligns with your specific noise filtering requirements.
