NAC-50-222

Power Line Filter Modules Overview

The Cosel NAC-50-222 is a single-phase EMC/EMI power line filter rated for 50A at 277VAC or 300VDC. It operates on 50/60Hz systems and utilizes a single-stage terminal block design. The component features a line-to-ground capacitance code of -222, providing a maximum leakage current of 0.25mA. It is engineered for high attenuation performance within the frequency range of 150kHz to 1MHz.

Power Line Filter Modules Feature Summary

• Designed for use in 277VAC factory distribution panels and building equipment
• Provides high attenuation characteristics from 150kHz to 1MHz
• Features low leakage current suitable for sensitive applications

Power Line Filter Modules Applications

• Factory distribution panels
• Building equipment
• Industrial machinery requiring EMI suppression

Power Line Filter Modules Procurement Notes

Verify the specific part number suffix against official Cosel documentation to confirm the line-to-ground capacitance code, as this directly determines the attenuation characteristics. Ensure the application voltage does not exceed the 277VAC or 300VDC ratings. Confirm terminal block compatibility with existing wiring infrastructure before procurement.

Power Line Filter Modules Selection Notes

Select this model when a single-phase filter with a 50A continuous current rating is required for 277VAC systems. The -222 suffix indicates a specific capacitance value that limits leakage current to 0.25mA, which is critical for safety compliance in certain installations. Compare attenuation curves in the datasheet against specific noise frequencies to ensure adequate filtering performance.

Power Line Filter Modules Part Context

This component belongs to the NAC-50 series of AC power line filters manufactured by Cosel USA, Inc. The series offers various configurations differentiated by current ratings and line-to-ground capacitance codes. These filters are designed to suppress electromagnetic interference in industrial and commercial power distribution environments.

Power Line Filter Modules Replacement Considerations

Direct substitutes include other models within the Cosel NAC-50 series, such as NAC-50-472 or NAC-50-223, provided their specific capacitance codes and resulting attenuation profiles match the system requirements. Verify that alternative parts maintain the same 50A current rating and physical mounting dimensions.
