FN3026HL-50-72

Overview

The Schaffner FN3026HL-50-72 is a three-phase EMC/RFI power line filter designed for industrial applications. It features a current rating of 50 A and a voltage rating of 520 VAC at 60 Hz. The unit utilizes a DIN rail mounting style with terminal block connections. Key electrical parameters include a leakage current of 410 µA and a power loss of 6.2 W. Physical dimensions are 150 mm in length, 78 mm in height, and 50 mm in depth. It operates within a temperature range of -25°C to 100°C.

Feature Summary

• Provides advanced electromagnetic compatibility filtering for three-phase power lines
• Designed for high-current industrial environments with 50 A capacity
• Utilizes compact DIN rail mounting for efficient panel integration
• Features low-leakage characteristics suitable for sensitive equipment

Applications

• Industrial motor drive systems
• Three-phase power distribution panels
• Manufacturing automation equipment
• Heavy machinery control units

Procurement Notes

Verify the specific part number suffix against official TE Connectivity/Schaffner documentation to ensure correct configuration. Confirm that the 50 A current rating and 520 VAC voltage specifications align with your system requirements. Check for required certifications such as UL, CSA, or IEC/EN depending on your regional compliance needs. Ensure terminal block compatibility with existing wiring infrastructure before procurement.

Selection Notes

Select this model when three-phase filtering is required for loads up to 50 A. The DIN rail form factor suits space-constrained enclosures where modular expansion is needed. Consider the 410 µA leakage current limit if connecting to sensitive electronic controls. Compare against the FN3025 series if chassis mounting is preferred over DIN rail installation for similar performance levels.

Part Context

This component belongs to the Schaffner FN3026 series, which offers advanced EMC filtering solutions. The HL variant typically denotes specific housing or terminal configurations within the broader product family. It is manufactured by TE Connectivity under the Schaffner brand, focusing on reliable noise suppression for critical power infrastructure.

Replacement Considerations

Direct substitutes may include other models from the FN3026 series with adjusted current ratings, such as the FN3026HL-30-71 for lower current applications. Verify mechanical fit and terminal type compatibility when considering cross-series replacements like the FN3025HP series.
