3-104-581

Overview

The SCHURTER 3-104-581 is a single-stage three-phase (Delta) EMC/EMI line filter from the FMAC NEO series. It features a rated voltage of 520 VAC at 50/60Hz and a rated current of 25 A. Designed for chassis mounting, it utilizes terminal block connections. The unit exhibits a leakage current of 10.70 mA and provides high attenuation performance suitable for general-purpose applications in industrial environments.

Feature Summary

• Single-stage filtering architecture for three-phase Delta systems
• High attenuation performance within a compact form factor
• Chassis mount construction with terminal block connectivity

Applications

• Industrial machinery power supply conditioning
• Three-phase motor drive input protection
• General-purpose EMC compliance for Delta networks

Procurement Notes

Verify that the application requires a three-phase Delta configuration, as this unit is not compatible with Wye systems. Confirm the terminal block connection method aligns with existing wiring infrastructure. Ensure the 25 A current rating and 520 VAC voltage specifications meet the system requirements before procurement.

Selection Notes

Select this component when high attenuation is required in a single-stage design for three-phase Delta systems. The FMAC NEO series offers a compact solution compared to multi-stage alternatives. Verify that the chassis mounting style fits the available enclosure space and that terminal block termination is preferred over screw or PCB options.

Part Context

This part belongs to the FMAC NEO series, representing SCHURTER's newer generation of single-stage filters. The series emphasizes compactness and high performance for three-phase applications. It serves as an upgrade path for legacy designs requiring improved EMC suppression in limited spaces.
