FN351-50-47

Overview

The FN351-50-47 is a three-phase power line filter module manufactured by Schaffner EMC Inc. Designed for chassis mounting, this component provides electromagnetic interference suppression in electrical systems. It supports a rated current of 50 A and operates within a frequency range of DC to 60 Hz. The unit is engineered for use with voltage levels up to 440 V. It features excellent saturation resistance, allowing for cable lengths up to 50 m without performance degradation. The filter is certified by CSA, ENEC, and UR agencies.

Feature Summary

• Provides general-purpose EMI filtering for three-phase power lines
• Features high saturation resistance suitable for long cable runs
• Supports chassis mounting for industrial integration

Applications

• Inverters
• Power Drive Systems
• Power supplies
• Battery chargers

Procurement Notes

Verify the specific ordering suffix matches the required configuration. Confirm that the chassis mounting style aligns with the installation environment. Ensure the 50 A current rating and 440 V voltage level meet the system requirements. Check for valid CSA, ENEC, and UR certifications if regulatory compliance is mandatory for the deployment region.

Selection Notes

Select this model when three-phase EMI suppression is required for drive systems or inverters. The 50 A capacity suits medium-power applications. Consider the chassis mount form factor for fixed installations. Evaluate the 50 m cable length capability if the filter is positioned remotely from the load. Verify frequency compatibility with the 60 Hz operating range.

Part Context

This component belongs to the FN351 series of general-purpose EMI filters. The series includes various current ratings and configurations for three-phase applications. The FN351-50-47 variant specifically addresses higher current demands compared to lower-rated models in the same family. It is categorized under power line filter modules for industrial noise reduction.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Review other FN351 series variants for current adjustments. Consult manufacturer guidelines for cross-referencing equivalent performance specifications.
