EAP-20-471

Power Line Filter Modules Overview

The Cosel EAP-20-471 is a single-phase power line filter designed for chassis mounting. It operates at a rated voltage of 250 VAC and 250 VDC with a current rating of 20 A. The unit features screw terminals for secure electrical connections and includes a ground capacitor value of 470 pF, resulting in a leakage current of 50 uA. Certified under UL, CSA, DIN, and ENEC standards, this component belongs to the EA series and is intended for effective electromagnetic interference suppression in AC and DC power circuits.

Power Line Filter Modules Feature Summary

• Provides common mode noise filtering for single-phase power lines
• Features screw-type terminal connections for robust installation
• Includes certified compliance for international safety standards

Power Line Filter Modules Applications

• Industrial machinery power input stages
• Medical equipment power supplies
• Test and measurement instrument protection

Power Line Filter Modules Procurement Notes

Verify the specific suffix designation when ordering, as variants such as -D may indicate different terminal configurations or packaging formats. Confirm that the chassis mount style and screw termination type align with your enclosure design requirements. Ensure the 20 A current rating and 250 VAC/VDC voltage limits are sufficient for your system's operational parameters before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this model when a 20 A capacity is required for single-phase applications. The 470 pF ground capacitance offers a balance between attenuation performance and leakage current constraints. Consider the chassis mount form factor if panel integration is preferred over PCB mounting. Verify that the screw terminal interface matches available wiring hardware.

Power Line Filter Modules Part Context

This component is part of the Cosel EA series of power line filters. The series provides various current ratings and capacitance options to suit different electromagnetic compatibility needs. The EAP-20-471 specifically addresses higher current demands compared to lower-rated siblings like the EAP-06-471, while maintaining similar voltage specifications and certification profiles within the product family.

Power Line Filter Modules Replacement Considerations

The EAP-20-332-D serves as a functional substitute within the same series, offering identical 20 A and 250 VAC/VDC ratings but with a different ground capacitance value of 330 pF. Verify that the altered capacitance meets your specific leakage current and filtering requirements before substitution.
