FN350-55-33

Overview

The Schaffner FN350-55-33 is a single-phase power line filter rated for 55 A and 250 V AC at 400 Hz. It features chassis mounting with terminal block connections. The unit provides high component value optimization for common and differential-mode attenuation in the lower frequency spectrum.

Feature Summary

• Single-stage compact EMC/RFI filter design
• Optimized for motor drive applications
• Industrial grade safety terminal blocks

Applications

• Single phase motor drive systems
• Aircraft electrical equipment
• Industrial control panels

Procurement Notes

Verify the specific voltage rating (250V AC) and current capacity (55A) against your system requirements. Confirm the 400Hz frequency specification matches your power source. Ensure chassis mounting dimensions and terminal block compatibility are validated before integration to prevent installation errors.

Selection Notes

Select this model for single-phase applications requiring robust attenuation at 400Hz. Consider the chassis mount form factor for panel integration. Evaluate the thermal performance if operating near the maximum current rating of 55A in enclosed environments.

Part Context

This component belongs to the FN350 series, which offers compact solutions for electromagnetic interference suppression. The series is designed for industrial and aerospace environments where space constraints and high reliability are critical. It serves as a primary defense against conducted noise on power lines.

Replacement Considerations

Check for direct equivalents within the FN350 series or other Schaffner single-phase filters. Verify that any substitute maintains the 55A current rating and 250V AC voltage tolerance. Ensure physical dimensions and terminal configurations match for seamless replacement.
