FN3270HQ1-400-99

Overview

The Schaffner FN3270HQ1-400-99 is a three-phase EMC/EMI power line filter designed for industrial motor drive applications. It features a compact chassis-mount design with busbar input and output terminations, suitable for Delta (3-wire + ground) configurations. The unit supports a rated voltage of 480 VAC to 520 VAC and handles a continuous current rating of 400 A at 60 Hz. Operating within a temperature range of -25°C to +100°C, it provides single-stage filtering to ensure electromagnetic compatibility in demanding environments.

Feature Summary

• Compact and lightweight construction optimized for minimal space requirements
• Busbar termination style for high-current industrial connections
• Single-stage filtering architecture for effective noise suppression

Applications

• Industrial motor drive systems
• High-power AC power conditioning
• Electromagnetic compatibility protection in heavy machinery

Procurement Notes

Verify the specific voltage rating requirement against the datasheet, as sources indicate both 480 VAC and 520 VAC ratings for this series. Confirm that the busbar termination matches the installation hardware. Ensure the application environment stays within the specified -25°C to +100°C operating temperature range to maintain performance and safety standards.

Selection Notes

Select this model when high current capacity near 400 A is required in a compact form factor. The busbar interface is critical for low-inductance connections in high-power setups. Consider the single-stage design if space constraints prevent larger multi-stage filters. Verify phase configuration compatibility with the Delta system before integration.

Part Context

This component belongs to the FN3270 series, which specializes in compact EMC filters for industrial applications. The HQ1 suffix typically denotes high-current variants with specific termination styles. This series is engineered to replace bulkier traditional filters while maintaining robust noise attenuation capabilities for sensitive electronic loads in industrial settings.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users must verify electrical compatibility and physical dimensions when considering alternative models from other manufacturers or different series within the same product line.
