Procurement Notes

Verify component authenticity through authorized TE Connectivity or Schaffner distributors. Confirm that the specific part number matches the required 690 VAC rating and 42 A current capacity. Check for updated compliance documentation regarding UL, CSA, and IEC/EN standards. Ensure replacement parts maintain identical terminal block configurations and mounting dimensions to fit existing chassis setups without modification.

Selection Notes

Select this model when system requirements exceed standard 480 VAC ratings but remain below higher voltage thresholds. The 42 A current rating suits medium-to-high power three-phase loads. Verify that the chassis mount style aligns with available panel space. Consider the operating temperature range if the installation environment experiences significant thermal variations. Ensure compatibility with existing safety grounding protocols due to the safety terminal block design.

Part Context

This component belongs to the FN258 series, which offers modular filter solutions for various current ratings. The HV variant specifically addresses high-voltage applications where standard filters may be insufficient. It complements other Schaffner products by providing specialized EMC suppression for three-phase power lines in industrial settings.
