FMAB-N7PI-0846

Power Line Filter Modules Overview

The FMAB-N7PI-0846 is a single-phase, first-stage AC line filter from the Schurter FMAB NEO series. It features a voltage rating of 277 VAC and a current capacity of 8 A. Designed for medical applications, it utilizes quick connect terminals with dimensions of 6.3 x 0.8 mm. The unit operates within a temperature range of -40°C to +100°C at 50/60 Hz. It incorporates enhanced asymmetrical attenuation performance through a ground line choke on the earth conductor, effectively filtering critical earth conductor currents generated by high-speed switching power supplies and motor drives.

Power Line Filter Modules Feature Summary

• Enhanced asymmetrical attenuation performance in higher frequencies achieved by adding a ground line choke on the earth conductor.
• Simple solution for filtering critical earth conductor currents generated by modern power conversion technologies.
• Ground line choke located between filter input and output to better address potential electromagnetic interference.

Power Line Filter Modules Applications

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

Power Line Filter Modules Procurement Notes

Verify the specific terminal type and insulation requirements against your system design before procurement. Confirm that the 8 A current rating and 277 VAC voltage specification align with your operational parameters. Ensure compatibility with the 6.3 x 0.8 mm quick connect terminals for proper electrical connection. Check for any specific medical compliance certifications required for your application environment.

Power Line Filter Modules Selection Notes

Select this component when addressing electromagnetic interference in single-phase systems requiring high-frequency attenuation. The integrated ground line choke makes it suitable for applications sensitive to earth conductor currents. Consider its compact form factor and screw or chassis mount options if space is limited. Evaluate its performance against standard filters if superior asymmetrical attenuation is necessary for your specific noise profile.

Power Line Filter Modules Part Context

This part belongs to the FMAB NEO series, which focuses on improving earth conduction filtering. Unlike standard filters, this series adds a second choke on the earth line to mitigate interference from modern power electronics. The main input earth connection is insulated from the housing, providing distinct isolation characteristics compared to traditional grounded designs.

Power Line Filter Modules Replacement Considerations

No public confirmed substitute part numbers are available for this specific model. When replacing, ensure the new component matches the 8 A rating, 277 VAC voltage, and quick connect terminal specifications. Verify that the replacement also offers ground line choke functionality if asymmetrical attenuation is required.
