NAM-40-471

Power Line Filter Modules Overview

The NAM-40-471 is a single-phase EMC/EMI line filter module manufactured by Cosel USA, Inc. It is designed for AC applications with a rated voltage of 277V and operates at 50/60Hz frequencies. The unit supports a continuous current of 40A and features a single-stage filtering architecture. Connection is facilitated via terminal block interfaces. Maximum leakage current specifications are listed as 5μA or 10μA under certain conditions, and up to 50μA or 100μA under others.

Power Line Filter Modules Feature Summary

• Single-stage electromagnetic interference suppression
• Terminal block connection interface
• Designed for single-phase AC power lines

Power Line Filter Modules Applications

• Industrial equipment power conditioning
• Commercial building electrical systems
• EMC compliance for sensitive electronics

Power Line Filter Modules Procurement Notes

Verify the specific datasheet version for leakage current ratings, as sources indicate variations (5/10μA vs 50/100μA). Confirm terminal block compatibility with existing wiring infrastructure. Ensure the 40A current rating aligns with the load requirements of the target circuit to prevent thermal overload during operation.

Power Line Filter Modules Selection Notes

Select this model when a single-phase solution is required for 277VAC systems. The 40A capacity suits moderate-power industrial loads. Consider the terminal block mounting style if DIN-rail or panel mount options are not available in alternative series. Validate that the single-stage design meets the specific attenuation requirements of the application environment.

Power Line Filter Modules Part Context

This component belongs to the NAM series of power line filters from Cosel. The series includes variants such as NAH-40-471 and NAP-40-471, which share similar form factors but may differ in internal capacitor configurations or specific leakage current characteristics. The NAM designation typically denotes a standard configuration within the manufacturer's lineup.

Power Line Filter Modules Replacement Considerations

The NAH-40-471 is a related model in the same series. Verify if the leakage current differences between NAM and NAH variants impact system safety grounding requirements before substitution.
