FN3359-800-99

Overview

The Schaffner FN3359-800-99 is a three-phase EMC/RFI power line filter designed for high-current industrial applications. It features an 800 A rated current and supports a maximum voltage of 520 VAC at frequencies between 0 Hz and 60 Hz. The unit utilizes busbar connections for both input and output, ensuring robust electrical interfaces. Key specifications include a leakage current of 5.1 mA and chassis mounting capabilities. Operating temperatures range from -25 °C to +100 °C, with physical dimensions of 386 mm in length, 260 mm in width, and 135 mm in height.

Feature Summary

• Designed for high-power IT network environments requiring robust electromagnetic interference suppression
• Utilizes busbar termination for secure and efficient high-current connectivity
• Constructed for chassis mounting to facilitate integration into industrial enclosures

Applications

• Electric machinery systems
• Motor drives and inverters
• IT network power conditioning

Procurement Notes

Verify the specific voltage rating requirement against the application's network standards, as this model is rated for 520 VAC. Confirm that the installation environment accommodates the specified physical dimensions and weight constraints associated with high-current busbar filters. Ensure compliance with relevant safety certifications such as UL and CSA prior to final procurement decisions.

Selection Notes

Select this component when applications demand high continuous current handling up to 800 A in three-phase configurations. Consider the busbar interface requirements for system integration rather than terminal block connections. Evaluate thermal management needs given the operating temperature range and ensure the mounting structure supports the unit's weight for stable chassis installation.

Part Context

This component belongs to the FN3359 series of high-performance EMC/RFI filters manufactured by Schaffner. The series is characterized by off-the-shelf availability for high-power applications. Variants within the series differ primarily in rated current capacity and voltage ratings, with some models supporting higher voltages like 690 VAC for specific IT network requirements.

Replacement Considerations

Direct substitutes within the same series include the FN3359-400-99 and FN3359-600-99 for lower current requirements. For higher voltage applications, the FN3359HV-800-99 is available. Verify that any replacement maintains the 520 VAC rating and busbar connection type to ensure compatibility.
