FN3359HV-400-99

Overview

The FN3359HV-400-99 is a three-phase EMC/RFI power line filter from the Schaffner FN3359 series, manufactured by TE Connectivity. It features a chassis mount design with busbar termination and operates within a frequency range of 0 Hz to 60 Hz. The unit has a voltage rating of 690 VAC and a current rating of 400 A. Physical dimensions are 386 mm in length, 260 mm in width, and 115 mm in height, with an operating temperature range of -25 °C to +100 °C.

Feature Summary

• Three-stage filtering architecture for high-current applications
• Chassis mount construction with busbar connections
• High leakage current specification of 5.1 mA

Applications

• Industrial motor drive systems
• Heavy-duty manufacturing equipment
• Power conversion units

Procurement Notes

Verify the specific voltage rating (690 VAC) against system requirements, as standard FN3359 models typically operate at 520 VAC. Confirm physical mounting constraints due to the chassis mount style and busbar termination type. Check lead times as production cycles may vary significantly based on order volume and factory schedules.

Selection Notes

Select this model specifically for high-voltage three-phase environments requiring 690 VAC compatibility. Ensure the installation site supports the required chassis mounting and busbar interface. Compare against standard FN3359 variants if the application voltage is lower, as those may offer different cost or availability profiles.

Part Context

This component belongs to the FN3359 series of three-phase EMC filters designed for industrial power conditioning. The HV suffix indicates a high-voltage variant capable of handling 690 VAC, distinguishing it from the standard 520 VAC versions within the same product family.

Replacement Considerations

FN3359-400-99 serves as a standard voltage alternative but requires verification of the 520 VAC rating suitability. No other direct substitutes are confirmed in public documentation.
