FN3258H-75-34

Overview

The FN3258H-75-34 is a three-phase EMC/RFI power line filter manufactured by TE Connectivity Schaffner. It features a rated voltage of 520 VAC and a current rating of 75 A, operating within a frequency range of 0 Hz to 60 Hz. The unit utilizes chassis mounting with terminal block termination and exhibits a leakage current of 4.7 mA. Physical dimensions are 240 mm in length, 80 mm in width, and 135 mm in height, weighing 2.7 kg. It complies with UL, CSA, and IEC/EN standards.

Feature Summary

• Ultra-compact and slim design optimized for minimal mounting space
• Single-stage filtering architecture for efficient noise suppression
• Terminal block connection method for secure electrical interfacing

Applications

• Industrial machinery requiring three-phase power conditioning
• Equipment installations with restricted physical clearance
• Systems demanding compliance with international EMC regulations

Procurement Notes

Verify the specific suffix 'H' against official datasheets to confirm high-voltage or specialized variant requirements. Ensure terminal block compatibility matches existing wiring infrastructure. Confirm that the 520 VAC rating aligns with the target system's nominal voltage levels before procurement.

Selection Notes

Select this model when standard filters exceed available spatial constraints. The 75 A rating suits moderate-to-high current applications. Verify that the chassis mount style fits the enclosure design. Consider the 4.7 mA leakage current impact on sensitive safety grounding schemes.

Part Context

This component belongs to the FN 3258 series, characterized by its ultra-compact form factor. The series targets applications where space efficiency is critical without compromising filtering performance. It serves as a solution for dense industrial control panels and compact machinery enclosures.

Replacement Considerations

Cross-reference part numbers such as FN3258-75-34 if the H-suffix denotes a specific non-standard variation. Verify dimensional tolerances and terminal block pinouts match exactly to ensure mechanical and electrical interchangeability.
