FMAB-N7PH-0446

Power Line Filter Modules Overview

The FMAB-N7PH-0446 is a single-phase first-stage AC power line filter from the Schurter FMAB NEO series. It features a 277 VAC voltage rating and a 4 A current capacity, designed for protection class II applications. The unit utilizes quick connect terminals with dimensions of 6.3 x 0.8 mm for secure electrical interfacing. Certified under UL, VDE, and IEC standards, it operates at 50 Hz and 60 Hz frequencies. The design incorporates enhanced asymmetrical attenuation performance in higher frequencies through an added ground line choke on the earth conductor, effectively filtering critical earth conductor currents generated by modern power conversion technologies.

Power Line Filter Modules Feature Summary

• Enhanced high-frequency asymmetrical attenuation achieved via an additional ground line choke on the earth conductor
• Effective mitigation of critical earth conductor currents produced by high-speed switching power supplies and motor drives
• Insulated main input earth connection from the housing to prevent interference

Power Line Filter Modules Applications

• High-speed switching power supply systems
• Frequency converters
• Motor drive applications

Power Line Filter Modules Procurement Notes

Verify that the specific part number FMAB-N7PH-0446 matches the required 277 VAC rating and 4 A current specification for your circuit design. Confirm compliance with UL, VDE, and IEC standards as documented in the official datasheet. Ensure the quick connect terminal type (6.3 x 0.8 mm) aligns with your PCB or wiring harness requirements before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this component when dealing with single-phase AC lines requiring robust filtering for high-frequency noise and earth conductor currents. The FMAB NEO series is suitable for environments utilizing frequency converters and motor drives where standard filters may not provide sufficient asymmetrical attenuation. Consider the chassis mount style and insulation characteristics if electromagnetic interference suppression is critical.

Power Line Filter Modules Part Context

This component belongs to the Schurter FMAB NEO series, which specializes in single-phase AC filters. The series distinguishes itself by integrating a second choke on the earth line between the filter input and output. This architectural improvement addresses potential electromagnetic interference more effectively than previous generations, making it a specialized solution for sensitive electronic equipment powered by modern switching technologies.

Power Line Filter Modules Replacement Considerations

Consult the official Schurter documentation for confirmed substitute part numbers within the FMAB NEO family. Verify that any replacement maintains the 277 VAC rating, 4 A current capacity, and quick connect terminal specifications to ensure functional compatibility.
