FN351H-50-33

Overview

The FN351H-50-33 is a three-phase EMC/RFI power line filter manufactured by TE Connectivity / Schaffner. It features a chassis mount installation style with terminal block termination. The component has a voltage rating of 520 VAC and a current rating of 50 A. Leakage current is specified at 32.7 mA. It operates within a frequency range of 0 Hz to 60 Hz. The unit weighs 1.6 kg and holds UL, CSA, and IEC/EN compliance certifications.

Feature Summary

• Provides broadband common mode and differential mode suppression for industrial power systems
• Designed specifically for use with industrial inverters and motor drive solutions
• Utilizes a robust chassis mount construction for secure mechanical integration

Applications

• Industrial inverter systems
• Motor drive solutions
• Three-phase power conditioning equipment

Procurement Notes

Verify the specific suffix 'H' against original design requirements, as it denotes a distinct variant from the standard FN351 series. Confirm that the 520 VAC rating aligns with the target application's electrical specifications. Ensure terminal block compatibility with existing wiring infrastructure before procurement.

Selection Notes

Select this model when a higher voltage rating of 520 VAC is required compared to the standard 440 VAC variants. The 50 A current capacity suits medium-to-large industrial loads. Verify that the chassis mount form factor fits the available enclosure space and thermal management requirements of the host system.

Part Context

This component belongs to the FN351H series, which represents an enhanced or specialized version of the broader FN351 family. While sharing similar mounting and termination characteristics with other models like the FN351-50-33, the H-series is distinguished by its specific voltage and leakage current parameters tailored for particular industrial environments.

Replacement Considerations

The FN351-50-33 is listed as a potential replacement; however, verify the voltage rating difference (440 VAC vs 520 VAC) and leakage current variations to ensure compatibility with the existing circuit design and safety standards.
