3-104-874

Overview

The SCHURTER 3-104-874 is a three-phase power line filter belonging to the FMAC NEO series. It is designed as a first-stage EMC/EMI filter for industrial applications. The unit supports a rated current of 64 A and operates at voltages up to 520 VAC. Key electrical specifications include a maximum leakage current of 3 mA and a voltage rating of 300 VAC or 520 VAC depending on configuration. The device features chassis mounting with screw termination and operates within a temperature range of -40°C to +100°C.

Feature Summary

• Provides single-stage electromagnetic interference suppression for three-phase systems
• Engineered for low leakage current operation to enhance safety
• Utilizes robust chassis mount construction with screw terminals

Applications

• Industrial machinery protection
• Three-phase power distribution systems
• EMC compliance in heavy equipment

Procurement Notes

Verify the specific voltage rating requirement (300 VAC vs 520 VAC) against your system design before ordering. Confirm that the chassis mounting dimensions and terminal types match your enclosure layout. Ensure the 64 A current capacity aligns with your load requirements. Check for any regional shipping restrictions or availability constraints prior to finalizing procurement plans.

Selection Notes

Select this component when a single-stage solution is sufficient for EMI reduction in three-phase environments. Consider the low leakage current specification if personnel safety or sensitive control circuits are a priority. Evaluate the thermal operating range to ensure compatibility with the installation environment. Compare physical dimensions against available panel space to confirm fitment.

Part Context

This filter is part of the FMAC NEO series, which focuses on compact and efficient filtering solutions. The product line emphasizes reliability in demanding industrial settings. SCHURTER designs these units to meet stringent international standards for electromagnetic compatibility. The series offers various configurations to suit different phase and current requirements.

Replacement Considerations

Consult official Schurter documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' filters without verifying electrical parameters and mounting interfaces.
