Overview
The Schaffner FN3311HV-400-99-C18-R55 is a three-phase busbar power line filter designed for high-voltage industrial applications. It features a rated voltage of 760 VAC and a continuous current rating of 400 A. The unit operates within a frequency range of 0 Hz to 60 Hz and maintains a leakage current of 0.09 mA. Certified under CSA, IEC/EN 60939, and UL 1283 standards, it utilizes chassis mounting with screw termination. Physical dimensions include a height of 165 mm and a length of 320 mm.
Feature Summary
- Provides electromagnetic interference suppression for three-phase power systems
- Engineered for high-current handling up to 400 amperes
- Supports high-voltage operation up to 760 volts AC
- Utilizes robust busbar connection architecture for secure installation
Applications
- Industrial motor drive systems
- High-power renewable energy inverters
- Heavy-duty manufacturing equipment power supplies
- Railway traction power systems
Procurement Notes
Verify the specific suffix codes against official Schaffner documentation to ensure correct configuration. Confirm that the 400A current rating aligns with system requirements. Check for regional sales restrictions or distribution limitations before ordering. Ensure compatibility with existing busbar mounting hardware and terminal specifications.
Selection Notes
Select this model when high current capacity and high voltage tolerance are required in a compact chassis-mount form factor. Consider the 0.09 mA leakage current specification for sensitive downstream electronics. Evaluate the physical dimensions (165mm height, 320mm length) against available enclosure space. Verify compliance with local safety standards such as UL 1283 or IEC 60939.
Part Context
This component belongs to the FN3311HV series, which focuses on high-voltage EMC filtering solutions. The series is characterized by its ability to handle significant electrical loads while maintaining strict electromagnetic compatibility. It serves as a critical interface between noisy power sources and sensitive industrial loads.
Replacement Considerations
Direct substitutes may include other models within the FN3311HV series with adjusted current ratings, such as the FN3311HV-250 or FN3311HV-600 variants, provided electrical parameters match the application needs. Cross-referencing datasheets is essential to confirm identical mounting and termination styles.
