FMAB-N6PH-0446

Power Line Filter Modules Overview

The FMAB-N6PH-0446 is a single-phase AC power line filter from the Schurter FMAB NEO series, rated for 277 VAC and 4 A. It features a first-stage design with M5 screw mounting and quick connect terminals (6.3 x 0.8 mm). The unit incorporates an earth line choke to enhance asymmetrical attenuation at higher frequencies, addressing interference from high-speed switching power supplies and motor drives. It complies with UL, CSA, and EN standards.

Power Line Filter Modules Feature Summary

• Enhanced asymmetrical attenuation performance in higher frequencies via added ground line choke
• Insulated earth connection at main input separated from housing
• Two earth connections located between filter input and output

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 against system requirements, as this differs from standard 250 VAC variants. Confirm terminal type compatibility with existing wiring harnesses. Ensure enclosure space accommodates the M5 mounting style and check that the insulated earth connection meets safety isolation requirements for Class II protection applications.

Power Line Filter Modules Selection Notes

Select this model when standard common-mode filtering is insufficient for high-frequency noise on the earth conductor. The FMAB NEO series is designed for critical earth conductor current filtering. Compare leakage current specifications if sensitive medical or precision equipment is involved. Verify that the 4 A current rating aligns with the maximum load current of the protected circuit.

Power Line Filter Modules Part Context

This component belongs to the FMAB NEO series, which introduces enhanced electromagnetic interference suppression capabilities compared to previous generations. The series specifically targets modern power conversion technologies that generate significant high-frequency noise. Schurter designs these filters to provide robust protection while maintaining compact form factors suitable for industrial and commercial control panels.

Power Line Filter Modules Replacement Considerations

FMAB-N6PH-0446 is a specific variant within the NEO family. Direct replacements must match the 277 VAC rating, 4 A capacity, and M5 mounting interface. Standard FMAB models without the NEO earth choke enhancement may not provide equivalent high-frequency asymmetrical attenuation.
