FN3271H-320-99

Overview

The Schaffner FN3271H-320-99 is a three-phase EMC/RFI power line filter designed for high-current industrial applications. It features a rated current of 320 A and a maximum voltage rating of 520 VAC at 60 Hz. The unit utilizes a chassis mount installation style with busbar termination for robust electrical connections. Key electrical parameters include a leakage current of 6.9 mA and a power loss of 6.8 W. Physical dimensions are 246 mm in length, 200 mm in width, and 86 mm in height, with an operating temperature range from -25°C to +100°C.

Feature Summary

• Provides effective electromagnetic interference suppression for three-phase power systems
• Engineered for high-capacity current handling up to 320 Amperes
• Utilizes durable busbar termination for secure low-inductance connections

Applications

• Industrial motor drives and variable frequency drives
• High-power renewable energy inverters
• Large-scale industrial machinery power supplies

Procurement Notes

Verify the specific part number suffix against official Schaffner documentation to ensure correct configuration. Confirm that the busbar termination type matches your system's mechanical interface requirements. Check for applicable regulatory certifications such as UL, CSA, or IEC/EN if required for your region. Ensure the ambient operating temperature remains within the specified -25°C to +100°C range during deployment.

Selection Notes

Select this component when a three-phase filter capable of handling 320 A continuous current is required. The 520 VAC rating suits standard industrial three-phase voltages. The chassis mount design with busbars is appropriate for high-current panels where screw terminals may be insufficient. Consider the physical footprint of 246x200x86 mm for enclosure planning.

Part Context

This model belongs to the FN3270 series of compact three-phase filters by Schaffner. It shares design lineage with variants like the FN3270H-35-33 but scales significantly for higher current demands. The series is characterized by its robust construction suitable for demanding industrial environments and high-efficiency filtering performance.

Replacement Considerations

The FN3270H-320-99 is listed as an alias for this part number. Verify compatibility with existing mounting structures due to the specific busbar interface. No direct cross-model substitutes are confirmed in the provided data without further engineering validation.
