Procurement Notes

Verify the specific suffix against official datasheets to confirm terminal type and certification status. Ensure the input voltage and current ratings match the system requirements before procurement. Confirm that the chassis mounting style aligns with the enclosure design. Check for any recent regulatory updates regarding IEC/EN standards applicable to the installation region.

Selection Notes

Select this component when space is limited within three-phase power architectures. The 7 A rating suits moderate load applications where compact form factors are critical. Verify compatibility with the existing terminal block wiring scheme. Consider the thermal environment to ensure operation remains within the specified -25°C to +100°C range during peak loads.

Part Context

This model belongs to the FN3258 series, which focuses on high-density EMC filtering solutions. The series is engineered specifically for modern motor drives and power electronics where physical footprint reduction is a primary design constraint. It represents a specialized subset of Schaffner's broader power line filter portfolio.

Replacement Considerations

Consult official substitution guides for equivalent models within the FN3258 series or compatible TE Connectivity portfolios. Verify that alternative parts maintain identical terminal block configurations and chassis mounting dimensions to ensure mechanical interchangeability without enclosure modifications.
