Procurement Notes
Verify the complete part number including the suffix against official Schaffner documentation to ensure correct configuration. Confirm that the required certification marks such as UL or CSA are explicitly listed for the specific variant. Cross-reference the terminal block type and physical dimensions with the mechanical drawings prior to integration into the final assembly design.
Selection Notes
Select this model when an 80 A capacity is required for three-phase systems operating at 520 VAC. Ensure the application environment falls within the specified -25°C to +100°C thermal limits. Verify that the chassis mounting style and terminal block connections align with the system's mechanical and wiring infrastructure requirements before procurement.
Part Context
This component belongs to the FN3256 series, which comprises compact three-phase filters designed for industrial use. The series emphasizes high attenuation and low leakage current characteristics. The FN3256H variant specifically addresses higher current demands while maintaining robust electromagnetic compatibility performance for demanding power electronics applications.
Replacement Considerations
Consult official Schaffner substitution guides for verified equivalents. Do not assume cross-compatibility with other series without confirming electrical ratings and mechanical fit.
