FN3280H-120-35

Overview

The Schaffner FN3280H-120-35 is a three-phase WYE (4-wire + ground) EMC/EMI line filter designed for chassis mounting. It features terminal block input and output connections, supporting a rated current of 120 A and operating voltages up to 520 VAC or 480 VDC at 60 Hz. This two-stage filter combines high attenuation performance with low leakage current and utilizes solid, touch-safe terminal blocks for secure electrical interfacing in industrial power applications.

Feature Summary

• Two-stage design providing high attenuation performance
• Solid, touch-safe terminal blocks for secure connection
• Low leakage current characteristics

Applications

• Industrial power distribution systems
• Three-phase motor drive protection
• EMC compliance for heavy machinery

Procurement Notes

Verify the specific voltage rating requirements against the datasheet, as sources cite both 480VAC and 520VAC. Confirm that the terminal block configuration matches the installation panel layout. Ensure the chassis mount dimensions are compatible with the enclosure design before procurement.

Selection Notes

Select this model for applications requiring robust three-phase filtering with high current capacity. The WYE configuration is suitable for systems utilizing a neutral conductor. Consider the chassis mount form factor when designing the equipment housing to ensure adequate space for heat dissipation and physical installation.

Part Context

This component belongs to the Schaffner FN3280 series, which specializes in three-phase and neutral line filters. The series is engineered to combine high attenuation with low leakage current, addressing stringent electromagnetic compatibility requirements in industrial environments while maintaining safety through touch-safe terminal designs.

Replacement Considerations

Check for exact pinout and terminal block compatibility when substituting. Verify that alternative models support the same 120 A current rating and WYE topology to maintain system integrity.
