FN3025HL-40-71

Overview

The Schaffner FN3025HL-40-71 is a three-phase EMC/RFI line filter designed for chassis mounting. It features a plastic housing with an integrated metal ground plate to minimize leakage current and enhance electromagnetic compatibility. The unit supports a rated voltage of 520 VAC and handles a continuous current of 40 A at frequencies up to 60 Hz. It utilizes ring terminal connections for both input and output, ensuring secure electrical interfaces. This single-stage filter is engineered for industrial applications where space efficiency and robust performance are critical.

Feature Summary

• Combines plastic housing with a metal ground plate for optimal EMC performance and low leakage current
• Features hinged safety covers and embedded filter terminals for enhanced operational safety
• Designed specifically for space-constrained中小型 industrial equipment installations

Applications

• Space-limited industrial machinery requiring efficient EMC filtering
• Chassis-mounted power distribution units in manufacturing environments
• Equipment needing low leakage current compliance for sensitive operations

Procurement Notes

Verify the specific part number suffix against official Schaffner documentation to confirm terminal type and mounting configuration. Ensure the application environment matches the 520 VAC rating and 40 A current capacity. Confirm that chassis mounting is feasible within the target enclosure design. Cross-reference lead times with authorized distributors as standard delivery periods may vary.

Selection Notes

Select this model when chassis mounting is preferred over DIN-rail installation for three-phase systems. Consider the 40 A current rating and 520 VAC voltage limit to ensure compatibility with the load requirements. Evaluate the need for low leakage current characteristics typical of the FN3025 series. Compare with the FN3026 series if DIN-rail mounting is required instead.

Part Context

This component belongs to the Schaffner FN3025 series, which includes lightweight filters for small to medium-sized industrial devices. The series distinguishes between chassis-mount (FN3025) and DIN-rail mount (FN3026) versions. The HL variant typically denotes specific terminal or performance characteristics within the broader product family, focusing on compact design and high reliability.

Replacement Considerations

Check for direct substitutes within the FN3025 series with different current ratings, such as FN3025HL-30-71. Verify mechanical dimensions and terminal compatibility before substituting. Consult official Schaffner cross-reference guides for approved alternatives.
