NAH-30-472

Power Line Filter Modules Overview

The Cosel NAH-30-472 is a single-phase power line noise filter rated for 30 A current and 250 VAC/DC voltage. It features a capacitance of 4.7 nF and operates within a frequency range of 10 kHz to 1 MHz. The device utilizes chassis mount installation with screw termination and exhibits a maximum leakage current of 0.5 mA. Certified by UL, CSA, DIN, VDE, and ENEC, it provides high attenuation performance for electromagnetic interference suppression in AC and DC power circuits.

Power Line Filter Modules Feature Summary

• Ultra-high attenuation performance across the 10 kHz to 1 MHz frequency spectrum
• Single-stage configuration designed for single-phase power line applications
• Spring-loaded captive push-down terminal design for secure electrical connections

Power Line Filter Modules Applications

• Electromagnetic compatibility (EMC) filtering for industrial equipment
• Electrostatic discharge (ESD) protection in power supply inputs
• Noise suppression for sensitive electronic instrumentation

Power Line Filter Modules Procurement Notes

Verify that the specific order matches the NAH-30-472 designation rather than the NAH-30-472-D variant, as suffixes may indicate different mounting configurations or packaging types. Confirm compliance requirements such as UL and VDE certifications are necessary for the intended deployment region. Ensure chassis mounting provisions align with the mechanical specifications provided in the official datasheet before procurement.

Power Line Filter Modules Selection Notes

Select this component when a 30 A continuous current rating and 250 VAC/DC operation are required for single-phase systems. The 4.7 nF capacitance value is suitable for standard EMI/EMC noise reduction tasks. Consider the chassis mount style and screw termination type during mechanical integration planning to ensure proper enclosure compatibility and thermal management.

Power Line Filter Modules Part Context

This model belongs to the Cosel NA series of power line filters, which are engineered for robust noise suppression in various electrical environments. The NAH-30-472 specifically addresses high-current applications requiring reliable EMC performance. It is distinct from lower current variants like the NAH-16 series and differs from DIN-rail mounted versions indicated by specific suffixes.

Power Line Filter Modules Replacement Considerations

The NAH-30-472-D is a related variant within the same product family. Verify if the specific mounting style or packaging difference associated with the '-D' suffix meets the application requirements before substituting.
