FN3025HP-50-72

Overview

The FN3025HP-50-72 is a three-phase EMC/RFI power line filter from the Schaffner FN 3025 series, manufactured by TE Connectivity. Designed for chassis mounting, this component supports a rated voltage of 520 VAC and a continuous current rating of 50 A. It operates within a frequency range of 0 Hz to 60 Hz and utilizes terminal block connections for both input and output. The unit features a Delta (3-wire + ground) configuration with ring terminals. Key electrical specifications include a leakage current of 410 µA and compliance with UL, CSA, and IEC/EN standards.

Feature Summary

• Provides electromagnetic interference suppression for three-phase power systems
• Engineered for high-performance applications with P Performance Level designation
• Utilizes a compact state-of-the-art filter concept with closed plastic covers

Applications

• Industrial machinery power distribution
• Three-phase motor drive systems
• Heavy-duty manufacturing equipment

Procurement Notes

Verify that the specific part number FN3025HP-50-72 matches the required P Performance Level, as other variants like HL exist within the same series. Confirm terminal block compatibility with existing wiring harnesses. Ensure chassis mounting provisions align with the enclosure design. Check for updated certification marks such as ENEC if operating in European markets. Validate that the 520 VAC rating suits the local grid voltage.

Selection Notes

Select this model when a 50 A capacity is required for three-phase Delta configurations. The HP suffix indicates specific performance characteristics distinct from HL variants. Consider the chassis mount style for fixed installations rather than DIN-rail setups. Evaluate the 410 µA leakage current against safety grounding requirements. Ensure the 0–60 Hz operational range covers the facility's power frequency.

Part Context

This component belongs to the Schaffner FN 3025 series, which offers compact power line filters for industrial use. The series includes various current ratings and performance levels. The FN3025HP-50-72 specifically targets high-current applications requiring robust EMI suppression. It is part of TE Connectivity's broader portfolio of electromagnetic compatibility solutions.

Replacement Considerations

The FN3025HL-50-72 is a related variant within the same series but may differ in performance level or internal configuration. Verify technical equivalence before substitution. No direct cross-manufacturer substitutes are confirmed in public documentation.
