FN354-4-05

Overview

The FN354-4-05 is a three-phase (Wye) EMC/EMI line filter from the FN 354 series, manufactured by Schaffner EMC Inc. It operates within a frequency range of DC to 60Hz and supports a rated AC voltage of 440VAC phase-to-phase with a current capacity of 4A. The component features a two-stage configuration for enhanced noise suppression and utilizes quick connect terminals for electrical interfacing. Designed for chassis mounting, it provides robust electromagnetic interference mitigation for power lines in industrial applications.

Feature Summary

• Three-phase Wye topology for balanced power line filtering
• Two-stage internal configuration for effective EMI attenuation
• Quick connect terminal style for simplified wiring integration

Applications

• Industrial motor drive systems
• Power distribution units requiring EMI suppression
• Electrical enclosures with chassis mounting requirements

Procurement Notes

Verify that the specific part number FN354-4-05 matches the required three-phase Wye configuration and 4A rating for your application. Confirm that the quick connect terminal type is compatible with your existing wiring harnesses. Ensure the chassis mounting footprint aligns with your enclosure design specifications before procurement.

Selection Notes

Select this component when a three-phase solution is required for frequencies up to 60Hz. The 4A current rating suits moderate load applications. Consider the two-stage design if higher attenuation is needed compared to single-stage alternatives. Verify that the 440VAC rating meets the system's voltage requirements.

Part Context

This component belongs to the FN 354 series of standard performance filters. It is designed for general industrial use where compact size and reliable EMI reduction are priorities. The series typically offers various current ratings and mounting options to suit different power electronics needs.

Replacement Considerations

Check official datasheets for direct pin-compatible substitutes within the FN 354 series. Ensure any replacement maintains the three-phase Wye configuration and equivalent current/voltage ratings.
