FMAB-N4PG-0146

Power Line Filter Modules Overview

The SCHURTER FMAB-N4PG-0146 is a single-phase, first-stage high-voltage power line filter designed for Class II protection. It features a rated voltage of 277 VAC and 400 VDC with a current rating of 1 A. The unit utilizes quick connect terminals and chassis mount installation. Key electrical parameters include a leakage current of 500 uA and operation at 50/60 Hz frequencies within a temperature range of -40°C to +100°C.

Power Line Filter Modules Feature Summary

• Enhanced asymmetrical attenuation performance in higher frequencies achieved through an added ground line choke on the earth conductor.
• Dual earth connections located between filter input and output, with the main input earth connection insulated from the housing.
• Designed to filter critical earth conductor currents generated by high-speed switching power supplies, frequency converters, and motor drives.

Power Line Filter Modules Applications

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

Power Line Filter Modules Procurement Notes

Verify the specific part number FMAB-N4PG-0146 against official Schurter documentation to confirm ratings. Ensure compatibility with 277 VAC / 400 VDC systems. Check insulation requirements for the earth connection relative to the housing. Confirm terminal type matches system design.

Power Line Filter Modules Selection Notes

Select this component when asymmetric EMI filtering on the earth line is required for Class II equipment. It is suitable for applications involving high-frequency noise from power conversion technologies. Verify that the 1 A current rating and 500 uA leakage current meet system safety standards.

Power Line Filter Modules Part Context

This model belongs to the FMAB NEO series, which introduces enhanced earth conduction capabilities. The series addresses electromagnetic interference issues common in modern power electronics by integrating chokes directly into the earth path rather than relying solely on traditional line-to-line or line-to-neutral filtering methods.

Power Line Filter Modules Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Consult Schurter technical support for direct equivalents or functional replacements within the FMAB series.

Power Line Filter Modules FAQ

How does the FMAB-N4PG-0146 handle earth conductor currents?

It uses a dedicated ground line choke located between the input and output to filter critical earth conductor currents generated by high-speed switching technologies.

What is the insulation characteristic of the earth connection?

The earth connection at the main input is insulated from the housing, while providing two earth connections at the input and output sides of the filter.
