NAH-40-472

Power Line Filter Modules Overview

The Cosel NAH-40-472 is a single-stage power line filter designed for AC and DC applications. It supports a rated current of 40A with voltage ratings of 300VDC and 277VAC at 50/60Hz. The unit features a chassis mount configuration with terminal block connections. Operating temperature range spans from -40°C to 85°C. Leakage current specifications are typically 5μA or 10μA depending on the variant context, ensuring compliance with safety standards for electromagnetic interference suppression in industrial environments.

Power Line Filter Modules Feature Summary

• Single-stage EMI/EMC filtering architecture for effective noise suppression
• Chassis mount design with terminal block interface for secure installation
• Wide operating temperature range suitable for harsh industrial conditions

Power Line Filter Modules Applications

• Industrial power supply units requiring EMI suppression
• AC/DC power distribution systems
• General purpose electronic equipment protection

Power Line Filter Modules Procurement Notes

Verify the specific datasheet version for leakage current values (5μA vs 10μA) as variants exist within the NAH series. Confirm terminal block compatibility with existing wiring infrastructure. Ensure chassis mounting dimensions align with enclosure specifications. Cross-reference part number suffixes to confirm exact rating configurations before procurement.

Power Line Filter Modules Selection Notes

Select this component when a single-stage filter is sufficient for the application's noise profile. The 40A rating dictates suitability for high-current loads. Consider the chassis mount form factor if panel integration is required. Evaluate thermal management needs given the 85°C upper limit. Compare against multi-stage options if higher attenuation is necessary.

Power Line Filter Modules Part Context

This component belongs to the Cosel NAH series of power line filters. The series includes variants such as NAH-40-222 and NAH-40-683, differing primarily in capacitance and leakage current characteristics. The NAH series is engineered for general-purpose industrial applications, offering a balance between performance and physical footprint for standard power conditioning tasks.

Power Line Filter Modules Replacement Considerations

Direct substitutes include other Cosel NAH-40 series models like NAH-40-222 or NAH-40-683, provided leakage current requirements match. Verify that alternative single-stage filters maintain the 40A current rating and 300VDC/277VAC voltage tolerance. Ensure mechanical mounting dimensions remain compatible with existing chassis cutouts.
