FMAB-N6PH-0346

Power Line Filter Modules Overview

The Schurter FMAB-N6PH-0346 is a single-stage high-voltage AC power line filter designed for Class II protection. It features a rated voltage of 277V AC and a current rating of 3A. The component utilizes quick connect terminals with M5 mounting hardware for secure installation. Certified to UL, CSA, and ENEC standards, it operates at 50/60Hz frequencies. This filter provides essential electromagnetic interference suppression for sensitive electronic equipment requiring reliable noise filtering in high-voltage applications.

Power Line Filter Modules Feature Summary

• Enhanced asymmetrical attenuation performance in higher frequencies achieved through an added ground line choke on the earth conductor.
• Effective filtering of critical earth conductor currents generated by modern power conversion technologies such as high-speed switching power supplies and motor drives.
• Insulated earth connection at the main input separated from the housing to ensure safety and proper grounding isolation.

Power Line Filter Modules Applications

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

Power Line Filter Modules Procurement Notes

Verify that the specific part number FMAB-N6PH-0346 matches your system's voltage and current requirements before procurement. Confirm terminal type compatibility with existing wiring harnesses. Ensure the mounting hardware aligns with your enclosure design. Check for required certifications such as UL or CSA based on regional regulatory needs. Validate insulation and leakage current specifications against safety standards.

Power Line Filter Modules Selection Notes

Select this model when dealing with high-voltage AC inputs around 277V where compact single-stage filtering is sufficient. Consider the enhanced earth line choke if managing significant common-mode noise from switching devices. Ensure the quick connect termination style fits your assembly process. Evaluate thermal management capabilities within the intended operating temperature range.

Power Line Filter Modules Part Context

This component belongs to the Schurter FMAB NEO series, which focuses on improved electromagnetic interference suppression. The series integrates a second choke on the earth line to address potential interference issues more effectively than standard filters. It represents an evolution in passive filtering technology tailored for modern power electronics environments.

Power Line Filter Modules Replacement Considerations

Direct substitutes must match the 277V AC rating, 3A current capacity, and single-phase configuration. Verify identical termination styles and mounting dimensions to ensure mechanical compatibility. Cross-reference certification approvals if operating in regulated markets. Consult official Schurter documentation for approved alternative part numbers within the FMAB NEO family.
