NAH-20-222

Power Line Filter Modules Overview

The Cosel USA, Inc. NAH-20-222 is a single-phase EMC/EMI power line filter module designed for chassis mounting. It features a rated current of 20 A and a rated voltage of 250 VAC/VDC. The device utilizes a terminal block termination style for electrical connections. This component serves as a single-stage filter to mitigate electromagnetic interference in AC power circuits.

Power Line Filter Modules Feature Summary

• Single-phase EMC/EMI line filtering capability
• Chassis mount construction for secure installation
• Terminal block termination style

Power Line Filter Modules Applications

• Industrial equipment power input stages
• Medical device power supplies
• Commercial machinery EMI suppression

Power Line Filter Modules Procurement Notes

Verify the specific part number suffix against official Cosel documentation to confirm exact pinout and certification status. Ensure the chassis mounting holes align with your enclosure design. Confirm that the 20A rating meets the continuous load requirements of the target application circuit before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this model when a single-phase, high-current (20A) solution is required for chassis-mounted applications. The terminal block interface simplifies wiring compared to PCB-mount alternatives. Verify that the 250VAC rating is sufficient for the local mains voltage environment and that the physical dimensions fit the available panel space.

Power Line Filter Modules Part Context

This component belongs to the Cosel NAH series of power line filters. The series offers various current ratings and capacitance options to suit different noise attenuation requirements. The NAH designation typically indicates a chassis-mount form factor within the manufacturer's product lineup.

Power Line Filter Modules Replacement Considerations

Cross-reference with NAC-20-222 or NAM-20-222 if DIN-rail mounting is preferred instead of chassis mounting. Verify that substitute models maintain the same 20A current rating and 250VAC voltage rating to ensure circuit compatibility.
