FMAB-N6PI-0846

Power Line Filter Modules Overview

The Schurter FMAB-N6PI-0846 is a single-phase, single-stage power line filter rated for 8 A and 277 VAC. It belongs to the FMAB NEO series, designed for applications with symmetrical noise from switching semiconductors. The unit features chassis mounting and utilizes M5 screw terminals for connection. It incorporates an earth line choke to enhance asymmetrical attenuation at higher frequencies, addressing interference from high-speed power conversion technologies.

Power Line Filter Modules Feature Summary

• Enhanced asymmetrical attenuation performance in higher frequencies achieved through an added ground line choke on the earth conductor.
• Specifically engineered to filter critical earth conductor currents generated by modern power conversion technologies such as frequency converters and motor drives.
• Features two earth connections where the main input earth is insulated from the housing to improve electromagnetic interference management.

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 your system requirements, as this differs from standard 250 VAC variants. Confirm that M5 screw terminal compatibility matches your wiring infrastructure. Ensure the chassis mount footprint aligns with your enclosure design constraints before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this component when dealing with symmetrical noise issues common in semiconductor switching applications. The integrated earth choke makes it suitable for environments requiring superior high-frequency asymmetrical attenuation compared to standard filters. Verify that the 8 A current rating meets the load demands without exceeding thermal limits.

Power Line Filter Modules Part Context

This part is a member of the FMAB NEO series, which focuses on compact, high-performance filtering solutions. The series distinguishes itself by integrating chokes directly into the earth path, a design choice aimed at mitigating interference from contemporary power electronics that generate significant common-mode noise on grounding lines.

Power Line Filter Modules Replacement Considerations

Direct substitutes within the same series include other FMAB NEO variants with different current ratings or terminal types, such as the 6 A or 20 A models. Ensure any replacement maintains the M5 terminal interface and 277 VAC rating if those are critical constraints.
