FN3258-75-34

Overview

The Schaffner FN3258-75-34 is a three-phase EMC/RFI power line filter rated for 75 A and 480 VAC at 60 Hz. Designed for chassis mounting with terminal block termination, it features an ultra-compact form factor measuring 240 mm in length, 80 mm in width, and 135 mm in height. The unit operates within a temperature range of -25°C to +100°C and exhibits a leakage current of 4.3 mA. It supports cable lengths up to 50 meters and holds UL, CSA, and IEC/EN certifications.

Feature Summary

• Ultra-compact and slim design optimized for space-constrained installations
• Terminal block termination for secure electrical connections
• Chassis mount configuration for stable mechanical integration

Applications

• Motor drive systems
• Industrial machinery
• Power conditioning equipment

Procurement Notes

Verify the specific part number against official TE Connectivity or Schaffner documentation to confirm ratings. Ensure the application environment matches the specified voltage, current, and temperature limits. Confirm that terminal block termination suits the wiring infrastructure. Check for required regional certifications such as UL or CSA before finalizing procurement.

Selection Notes

Select this component when high current capacity is required in a minimal footprint. The 75 A rating and 480 VAC specification suit heavy-duty industrial loads. The low leakage current of 4.3 mA minimizes safety risks. Verify that the chassis mounting style aligns with the enclosure design and that terminal blocks are compatible with the available wiring gauge.

Part Context

This component belongs to the FN3258 series, which provides ultra-compact three-phase filtering solutions. The series is engineered for motor drive applications where space is limited. It shares common design principles with other models in the family, focusing on slim profiles and robust performance under industrial conditions.

Replacement Considerations

Compatible substitutes include FN3258-100-35 for higher current requirements and FN3258-42-33 for lower current needs. Ensure replacement parts maintain the same chassis mount style and terminal block termination to fit existing enclosures without modification.
