NAH-20-331

Power Line Filter Modules Overview

The Cosel USA, Inc. NAH-20-331 is a single-phase EMC/EMI power line filter designed for chassis mounting. It supports AC and DC voltages up to 250V with a rated current of 20A. The component features terminal block termination and operates within a temperature range of -40°C to 85°C. Leakage current specifications are defined at maximum values of 37.5 µA and 75 µA under specific test conditions.

Power Line Filter Modules Feature Summary

• Provides single-stage electromagnetic interference suppression for power lines
• Supports both AC and DC voltage applications up to 250V
• Designed for secure chassis mounting using terminal block connections

Power Line Filter Modules Applications

• Industrial equipment requiring EMI filtering
• Power supply input stages
• Electronic systems operating in noisy environments

Power Line Filter Modules Procurement Notes

Verify the exact suffix designation when ordering, as variants such as NAH-20-331-D exist with different mounting options like DIN rail. Confirm that the chassis-mount configuration matches your enclosure requirements. Ensure the 20A current rating and 250V voltage limits align with your system's electrical specifications before procurement.

Power Line Filter Modules Selection Notes

Select this model if chassis mounting is preferred over DIN rail installation. Compare leakage current requirements against the specified maximums of 37.5 µA and 75 µA. Ensure the operating temperature range of -40°C to 85°C meets environmental demands. Verify compatibility with terminal block wiring methods versus other termination styles available in the series.

Power Line Filter Modules Part Context

This component belongs to the NAH-20 series from Cosel USA, Inc., which includes various power line filter modules. The series offers different configurations, including chassis mount and DIN rail versions, with varying voltage and current ratings. The NAH-20-331 specifically denotes the chassis-mounted variant with standard terminal block termination.

Power Line Filter Modules Replacement Considerations

The NAH-20-331-D serves as a related variant within the same series but utilizes DIN rail mounting instead of chassis mounting. When substituting, verify that the mechanical mounting interface and termination style differences do not conflict with existing hardware constraints.
