Procurement Notes

Verify the specific terminal type, as datasheets indicate both strip and block variants within this series. Confirm compliance requirements such as UL or CSA against project specifications. Check current availability status as some listings indicate discontinued status. Ensure the 440 VAC rating aligns with the target system voltage. Validate physical dimensions for chassis cutout compatibility prior to procurement.

Selection Notes

Select this model when a 42 A continuous current capacity is required for three-phase systems. Consider the 440 VAC rating for appropriate voltage headroom. Evaluate the 33 mA leakage current against safety grounding limits. Compare physical dimensions against available panel space. Verify that the operating temperature range meets environmental conditions.

Part Context

This component is part of the Schaffner FN 3258 series, which specializes in ultra-compact filtering solutions. The series targets high-density electronic environments where space is limited but robust EMI performance is critical. It serves as a specialized power conditioning element within larger electrical assemblies.

Replacement Considerations

FN3258-42-33 is listed as a potential replacement variant within the same series. Verify terminal interface compatibility between the -47 and -33 suffixes before substitution. Ensure current and voltage ratings remain sufficient for the application.
