FMAB-N4PK-2046

Power Line Filter Modules Overview

The SCHURTER FMAB-N4PK-2046 is a single-phase, first-stage power line filter rated for 277 VAC and 20 A. Designed for Class II protection, it utilizes quick connect termination and DIN rail mounting. The component operates at 50/60 Hz with low leakage current characteristics. It holds CSA, ENEC, UR, and IEC certifications, ensuring compliance with international safety standards for industrial and commercial electrical systems.

Power Line Filter Modules Feature Summary

• Enhanced asymmetrical attenuation performance in higher frequencies achieved by adding a ground line choke on the earth conductor
• Second choke on the earth line located between filter input and output to better address potential electromagnetic interference
• Insulated earth connection at the main input separated from the housing to improve earth conduction

Power Line Filter Modules Applications

• High-speed switching power supplies
• Frequency converters
• Motor drives

Power Line Filter Modules Procurement Notes

Verify the specific voltage rating of 277 VAC and current capacity of 20 A against system requirements. Confirm that the quick connect termination type matches existing wiring infrastructure. Ensure DIN rail compatibility within the installation enclosure. Check for required certifications such as UL or CSA depending on regional deployment regulations.

Power Line Filter Modules Selection Notes
