NAH-40-683

Power Line Filter Modules Overview

The Cosel NAH-40-683 is a single-phase EMC/EMI power line filter rated for 40 A and 277 VAC. It provides high attenuation from 9 kHz to 1 MHz, meeting stringent emission standards. The unit features a chassis mount design with terminal block connections. Operating temperature ranges from -40°C to +85°C. It is certified by UL, CSA, and TUV under safety standards 60950-1 and 62368-1.

Power Line Filter Modules Feature Summary

• Ultra-high attenuation performance across the 9 kHz to 1 MHz frequency range
• Chassis-mount construction with terminal block interface
• Compliance with international safety certifications including UL, CSA, and TUV

Power Line Filter Modules Applications

• Industrial machinery requiring EMI suppression
• Commercial ITE equipment power input stages
• Regenerative motor drive systems

Power Line Filter Modules Procurement Notes

Verify the specific suffix (e.g., -F) against your schematic requirements, as packaging or terminal variations may exist within the series. Confirm that the 277VAC rating aligns with your local mains voltage infrastructure. Ensure chassis mounting provisions match your enclosure design constraints before finalizing procurement orders.

Power Line Filter Modules Selection Notes

Select this model when high current capacity of 40A is required alongside strict EMI compliance. The wide operating temperature range supports harsh industrial environments. Verify that the single-phase configuration matches your system topology. Consider the physical dimensions for adequate heat dissipation space in enclosed installations.

Power Line Filter Modules Part Context

This component belongs to the NAH series of ultra-high attenuation filters from Cosel. It complements other power conditioning modules like the NAC series. The product line focuses on robust EMI suppression for demanding applications where standard filters fail to meet regulatory limits.

Power Line Filter Modules Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Evaluate equivalent 40A single-phase filters from other manufacturers only if they match the 277VAC rating, 9kHz-1MHz attenuation profile, and chassis mount form factor.
