Procurement Notes

Verify the specific suffix 'HVIT' against official Schaffner documentation to confirm high-voltage insulation ratings and terminal block specifications. Ensure compatibility with existing chassis mounting holes and terminal spacing before procurement. Cross-reference the 55 A rating with actual load requirements to prevent derating issues.

Selection Notes

Select this model when high current capacity and robust mechanical termination are required for three-phase AC lines. The HVIT designation indicates specific high-voltage insulation properties suitable for demanding industrial environments. Confirm that the chassis mount style aligns with the available panel space and thermal management strategy of the host equipment.

Part Context

This component belongs to the FN258 series, which provides state-of-the-art EMC filtering for inverters. The series is characterized by its book-style form factor and integration of safety terminals. It is manufactured by Schaffner EMC Inc., now part of TE Connectivity, specializing in electromagnetic compatibility solutions for power electronics.

Replacement Considerations

Direct substitutes include other models within the FN258 series with matching current ratings, such as FN258-55-34, provided the high-voltage insulation and terminal block differences are evaluated. Verify electrical parameters and physical dimensions before substitution.
