FN3271H-1000-99

Overview

The Schaffner FN3271H-1000-99 is a three-phase compact EMC/EMI line filter rated for 520VAC and 1000A. It utilizes a delta configuration and features busbar termination with chassis mounting. The unit operates within a temperature range of -25°C to +100°C at 60Hz. Dimensions are approximately 456mm length, 280mm width, and 170mm height, weighing 18kg. Leakage current is specified at 5.3mA. It holds UL, CSA, and IEC/EN compliance certifications.

Feature Summary

• Engineered for high-current power electronics applications
• Compact design suitable for space-constrained installations
• Provides effective EMI/RFI attenuation in three-phase systems

Applications

• High-power industrial drive systems
• Large-scale renewable energy inverters
• Heavy-duty manufacturing equipment

Procurement Notes

Verify the specific part number suffix against official datasheets to confirm terminal type and certification requirements. Ensure mechanical dimensions and weight constraints align with the installation site. Confirm that the busbar termination method matches existing infrastructure. Cross-reference compliance certificates such as UL and IEC/EN with local regulatory standards before finalizing procurement decisions.

Selection Notes

Select this component when high current capacity near 1000A is required in a three-phase delta configuration. Consider the physical footprint and 18kg weight for structural support planning. Evaluate thermal management needs given the operating temperature range up to 100°C. Ensure compatibility with busbar connections rather than standard wire terminals.

Part Context

This model belongs to the FN3271H series from Schaffner, designed for robust electromagnetic interference suppression in demanding electrical environments. The series targets applications requiring significant current handling capabilities while maintaining strict emission limits. It represents a specialized solution within the broader portfolio of power line filters offered by the manufacturer.

Replacement Considerations

Direct substitutes include other models within the FN3271H series or compatible units from the FN3270H series if current ratings allow. Verify that any replacement maintains the same 520VAC rating and busbar termination style. Ensure dimensional compatibility to avoid modifying the chassis mount structure.
