Procurement Notes

Verify the exact suffix designation against official Schaffner documentation, as variations such as FN3258-42-47 or FN3258P-42-47 exist within the same family. Confirm that the 'H' suffix does not imply a specific variant difference without explicit datasheet confirmation. Ensure compatibility with 440 VAC systems and 42 A load requirements before procurement.

Selection Notes

Select this model when high-current three-phase filtering is required in compact enclosures. Compare against standard FN3258 variants to ensure the specific terminal type and voltage rating match the system architecture. Verify that the 33 mA leakage current is acceptable for the connected equipment safety standards.
