NAH-40-223

Power Line Filter Modules Overview

The NAH-40-223 is a single-phase EMC/EMI line filter manufactured by Cosel USA, Inc. It supports a continuous current of 40 A and operates at rated voltages of 277 V AC and 300 V DC. The device functions within a frequency range of 50/60 Hz and utilizes a single-stage configuration for noise suppression. It employs terminal block connections for circuit integration and is designed for chassis mounting applications.

Power Line Filter Modules Feature Summary

• Provides electromagnetic interference suppression for single-phase power lines
• Supports high input voltage operation up to 300 V DC
• Utilizes a single-stage filtering configuration
• Designed for secure chassis mounting

Power Line Filter Modules Applications

• General purpose industrial equipment
• ITE (Information Technology Equipment)
• Power supply input stages

Power Line Filter Modules Procurement Notes

Verify the specific suffix against official Cosel documentation to confirm voltage ratings and termination types. Ensure the selected variant matches the required 40 A current capacity and 277 V AC / 300 V DC operating parameters. Confirm chassis mounting compatibility with the target enclosure design before procurement.

Power Line Filter Modules Selection Notes

Select this component when a single-phase filter with 40 A capacity is required for systems operating at 277 V AC or 300 V DC. Consider the NAH-40-223-F variant if flexible lead termination is preferred over rigid terminal blocks. Verify that the single-stage attenuation meets the specific EMI requirements of the application environment.

Power Line Filter Modules Part Context

This model belongs to the NAH series of power line filters from Cosel. The series includes variants such as NAH-40-222 and NAH-40-223-F, which share similar form factors but differ in voltage ratings and connection methods. The NAH series is engineered for robust performance in industrial and commercial power distribution networks.

Power Line Filter Modules Replacement Considerations

The NAH-40-223-F serves as a direct functional substitute offering identical electrical specifications with flexible leads instead of terminal blocks. Other NAH-40 variants may require verification of voltage ratings to ensure compatibility with the 277 V AC / 300 V DC system constraints.
