FN3359HV-250-28

Overview

The FN3359HV-250-28 is a three-phase power line filter from the Schaffner FN3359 series, designed for high-current industrial applications. It features a rated voltage of 690 VAC and a nominal current capacity of 250 A, with a maximum current rating of 400 A. The unit utilizes chassis mounting and terminal block termination. Key electrical specifications include a leakage current of 7.5 mA and an operating temperature range from -25°C to +100°C. Physical dimensions are 370 mm in length and 125 mm in height.

Feature Summary

• Designed for high-current three-phase power line filtering applications
• Utilizes chassis mount installation style with terminal block connections
• Capable of operating within a wide temperature range up to +100°C

Applications

• Industrial machinery requiring robust electromagnetic interference suppression
• High-power three-phase AC power distribution systems
• Equipment demanding compliance with strict EMC standards at elevated currents

Procurement Notes

Verify the specific suffix codes against official TE Connectivity/Schaffner documentation to ensure correct configuration. Confirm that the 690 VAC rating and 250 A current capacity align with your system requirements. Check for any specific environmental certifications or regional compliance markings required for your deployment location before finalizing procurement.

Selection Notes

Select this component when three-phase filtering is required for currents around 250 A at voltages up to 690 VAC. Ensure the chassis mount form factor fits the available enclosure space. Consider the 7.5 mA leakage current if sensitive downstream equipment is present. Verify that the terminal block termination method matches the existing busbar or cable infrastructure.

Part Context

This model belongs to the FN3359 series, which focuses on high-current EMC solutions. The HV designation typically indicates high-voltage capability suitable for industrial mains. It serves as a critical interface between noisy power sources and sensitive loads, ensuring signal integrity in heavy-duty electrical environments.

Replacement Considerations

Consult official cross-reference guides for direct substitutes. Ensure any replacement maintains the 690 VAC rating and comparable current handling capabilities. Verify physical footprint compatibility for chassis mounting.
