NAM-20-221

Power Line Filter Modules Overview

The NAM-20-221 is a single-phase power line filter from the Cosel USA NAM series, designed for electromagnetic compatibility (EMC) and electromagnetic interference (EMI) suppression. It features a rated current of 20 A and supports voltage ratings of 250 VAC and 250 VDC. The unit incorporates a capacitance value of 220 pF to achieve low leakage current performance, with maximum leakage specified at 25 uA or 50 uA depending on configuration. This component utilizes a single-stage filtering architecture and is intended for chassis mounting applications.

Power Line Filter Modules Feature Summary

• Provides single-stage EMC/EMI noise suppression for AC and DC power lines
• Engineered for low leakage current operation to ensure personnel safety
• Supports both AC and DC input voltage environments

Power Line Filter Modules Applications

• Industrial control systems requiring EMI filtering
• Medical equipment power inputs
• Electronic test and measurement instruments

Power Line Filter Modules Procurement Notes

Verify the specific terminal type required for your application, as the NAM series includes variants with different connection methods such as screw terminals or push-down terminals. Confirm that the 20 A current rating and 250 VAC/VDC voltage limits align with your system's operational parameters before procurement.

Power Line Filter Modules Selection Notes

Select this model when a 20 A capacity is sufficient for the load. Compare against the NAM-30-221 if higher current handling is needed. Ensure the chassis mount form factor fits the available enclosure space. Verify that the low leakage current specification meets regulatory requirements for the specific end-use environment.

Power Line Filter Modules Part Context

This component belongs to the Cosel USA NAM series of power line filters. The series offers various current ratings and terminal configurations to suit different industrial and commercial power conditioning needs. The NAM-20-221 specifically addresses applications requiring moderate current capacity with strict leakage current limitations.

Power Line Filter Modules Replacement Considerations

The NAM-30-221 serves as a higher-current alternative within the same series. Users requiring different terminal connections should consider NBM-series equivalents which utilize push-down terminals instead of screw terminals.
