FN3026HP-50-72

Overview

The Schaffner FN3026HP-50-72 is a three-phase EMC/RFI power line filter designed for DIN rail mounting. It supports a rated current of 50 A and operates at voltages up to 520 V AC at 60 Hz. The unit features screw terminals and maintains a low leakage current of 400 µA. Operating temperatures range from -25°C to 100°C, with physical dimensions of 150 mm length, 78 mm height, and 50 mm depth.

Feature Summary

• Compact plastic housing optimized for DIN rail installation
• Low leakage current design suitable for sensitive equipment
• Three-phase filtering capability for industrial power lines

Applications

• Industrial machinery power conditioning
• Variable frequency drive input protection
• Medical equipment power supply filtering

Procurement Notes

Verify the specific suffix code against official datasheets to confirm terminal type and voltage ratings. Confirm that the 50 A rating aligns with your system's continuous load requirements. Ensure DIN rail compatibility matches your enclosure standards before procurement.

Selection Notes

Select this model when high current capacity in a compact form factor is required. The low leakage current specification makes it appropriate for applications where safety isolation is critical. Verify that the 520 V AC rating exceeds your maximum line voltage.

Part Context

This component belongs to the FN3026 series, which focuses on compact three-phase filtering solutions. The HP designation typically indicates high-performance characteristics within the Schaffner portfolio. It serves as an alternative to bulkier chassis-mounted filters in space-constrained panels.

Replacement Considerations

Cross-reference with FN3026HL variants if different terminal configurations are needed. Verify dimensional compatibility with existing DIN rail layouts when substituting.
