3-138-366

Overview

The SCHURTER Inc. 3-138-366 is a three-phase (Wye) EMC/EMI line filter module designed for industrial power systems. It features a two-stage filtering architecture to suppress electromagnetic interference and radio frequency noise. The unit supports a continuous current rating of 50 A at frequencies between 50 Hz and 60 Hz. Rated for 760 VAC, it utilizes chassis mounting with terminal block and threaded post (M6) connections.

Feature Summary

• Two-stage filtering design for effective EMI/RFI suppression
• Chassis mount construction for secure installation
• Terminal block and M6 threaded post connection options

Applications

• Industrial power system noise suppression
• Three-phase equipment protection
• EMC compliance in manufacturing environments

Procurement Notes

Verify the specific Wye configuration and 50A current rating against your system requirements. Confirm that the 760VAC voltage rating matches your network. Ensure chassis mounting space accommodates the physical dimensions and that M6 threaded posts align with your panel layout before ordering.

Selection Notes

Select this model when high-current three-phase filtering is required. Compare its two-stage performance against single-stage alternatives if stricter attenuation is needed. Verify that the 50A capacity exceeds your peak load demands to ensure reliable operation under full load conditions.

Part Context

This component belongs to Schurter's Power Line Filter Modules category. It is engineered for robust industrial applications where electromagnetic compatibility is critical.
