3-138-355

Overview

The SCHURTER 3-138-355 is a three-phase (Wye) EMC/EMI power line filter module rated for 110 A at 520 VAC. It features a two-stage design with terminal block and threaded post (M6) connections. Operating frequencies are 50 Hz and 60 Hz, with a leakage current of 9.42 mA. The unit measures 130 mm in length and 91 mm in height, functioning within a temperature range of -40°C to +100°C.

Feature Summary

• Two-stage attenuation design for high performance
• Includes three-phase, neutral, and ground terminals
• Industrial-grade construction

Applications

• Variable frequency drives
• Inverter systems
• Uninterruptible power supply (UPS) systems
• Stepper motor drivers
• General machine applications

Procurement Notes

Verify the specific electrical rating configuration against the official datasheet, as manufacturer listings may reference varying current ratings such as 36 A or 110 A for similar model series identifiers. Confirm that the M6 threaded post termination matches the installation requirements. Ensure the operating voltage of 520 VAC aligns with the target circuit specifications before procurement.

Selection Notes

Select this component when high attenuation is required for three-phase industrial equipment. The two-stage architecture supports demanding environments like inverters and UPS systems. Verify compatibility with the 520 VAC system voltage and ensure sufficient panel space for the 130 x 91 mm footprint. Check if the standard industrial version meets the specific leakage current constraints of the application.

Part Context

This part belongs to the FMBD EP series of power line filter modules by SCHURTER. These modules are designed for clean and safe power supply in industrial settings. The series typically offers robust EMC protection for sensitive electronic loads, integrating directly into machinery and drive systems to mitigate electromagnetic interference.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users must verify cross-compatibility based on identical electrical ratings (110 A, 520 VAC), physical dimensions, and mounting interface specifications.
