3-138-359

Overview

The SCHURTER 3-138-359 is a three-phase (Wye) EMC/EMI line filter module designed for industrial power applications. It features a two-stage filtering architecture to suppress electromagnetic interference and noise in three-phase power systems. The unit has a rated current of 25 A at operating frequencies of 50 Hz and 60 Hz. It utilizes terminal block connections with threaded M6 posts for secure installation. The filter is engineered to operate within a temperature range of -40°C to +100°C, ensuring reliability in demanding environments.

Feature Summary

• Two-stage EMC/EMI filtering architecture for effective noise suppression
• Designed specifically for three-phase Wye power system configurations
• Utilizes threaded M6 post terminal blocks for robust electrical connections

Applications

• Three-phase industrial power distribution systems
• Electromagnetic interference suppression in sensitive electronic equipment
• Power quality improvement in 50/60 Hz AC networks

Procurement Notes

Verify the specific phase configuration (Wye) and current rating (25A) against your system requirements before procurement. Confirm that the M6 threaded post terminals are compatible with your existing busbar or wiring infrastructure. Ensure the operating temperature range meets your environmental conditions. Cross-reference the datasheet for leakage current and insertion loss specifications if critical for your application design.

Selection Notes

Select this model when a two-stage filtering solution is required for three-phase Wye systems. Compare its physical dimensions and mounting style against available space constraints. Evaluate the thermal performance relative to ambient temperatures, as it supports up to 100°C. Consider the mechanical strength of the M6 terminal connections for high-vibration environments compared to screw clamp alternatives.
