• General-purpose industrial machinery

Procurement Notes

Verify the specific suffix SEW against official datasheets to confirm mechanical or regulatory variations. Confirm availability status as this component may be obsolete or discontinued. Ensure compatibility with existing chassis mounting holes and terminal block spacing before procurement.

Selection Notes

Select this model for applications requiring 8 A continuous current handling in three-phase configurations. Consider the 520 VAC rating for higher voltage industrial networks. Evaluate the low leakage current specification if sensitive equipment is connected downstream.

Part Context

This component belongs to the FN351H series from Schaffner, designed for robust electromagnetic interference suppression. The series typically offers high attenuation performance suitable for demanding industrial environments where compliance with international standards is required.

Replacement Considerations

Check for direct substitutes within the FN351H series with matching current ratings. Verify that alternative models maintain the same terminal block configuration and chassis mounting dimensions to ensure physical compatibility.
