3-138-345

Overview

The SCHURTER Inc. model 3-138-345 is a three-phase (Delta) EMC/EMI line filter module designed for industrial applications. It features a rated current of 25 A and operates at AC voltages within the 50 to 60 Hz frequency range. The unit utilizes a two-stage filtering architecture to ensure effective noise suppression. Installation is facilitated through chassis mounting, and electrical connections are established via terminal blocks with threaded M6 posts.

Feature Summary

• Provides two-stage electromagnetic interference suppression for three-phase power lines
• Engineered for robust chassis mounting in industrial environments
• Utilizes secure threaded post terminal connections for reliable electrical interfacing

Applications

• Industrial machinery power conditioning
• Three-phase motor drive systems
• Factory automation control panels

Procurement Notes

Verify that the specific application requires a Delta configuration rather than Wye. Confirm that the system voltage does not exceed the component's rating. Ensure the mounting chassis accommodates the physical dimensions of the module. Check that the required cable gauge fits the M6 threaded terminals securely.

Selection Notes

Select this component when high-current three-phase filtering is necessary. The 25 A rating suits moderate power loads. Consider the two-stage design for stringent emission requirements. Evaluate space constraints for chassis installation. Compare against single-stage alternatives if cost or size is critical.

Part Context

This module belongs to Schurter's power line filter series, focusing on EMI/EMC compliance. It addresses conducted noise in sensitive electronic equipment. The product supports global industrial standards for power quality. It complements other Schurter components like fuses and switches in complete power management assemblies.
