3-138-344

Overview

The SCHURTER Inc. part number 3-138-344 is a three-phase (Delta) EMC/EMI power line filter module designed for industrial applications. It features a two-stage filtering architecture to suppress electromagnetic interference effectively. The unit has a current rating of 16 A and operates at frequencies of 50 Hz or 60 Hz with a voltage rating of 760 VAC. Constructed with a metal housing, it supports chassis mounting and utilizes terminal block connections with threaded posts (M6). The operating temperature range spans from -40°C to 100°C.

Feature Summary

• Two-stage EMC/EMI filtering architecture for enhanced noise suppression
• Metal housing construction for durability and thermal management
• Chassis mounting style with M6 threaded post terminal blocks

Applications

• Industrial machinery power conditioning
• Three-phase AC power distribution systems
• EMC compliance in sensitive electronic environments

Procurement Notes

Verify the specific voltage rating (760 VAC) and current capacity (16 A) against your system requirements before procurement. Confirm that the chassis mounting dimensions and M6 terminal configuration match your installation space. Ensure the operating temperature range of -40°C to 100°C is suitable for your environmental conditions. Check for any specific certification requirements relevant to your region.

Selection Notes

Select this component when a robust, two-stage solution is required for three-phase Delta systems. The metal housing makes it suitable for harsh industrial environments where durability is critical. Consider the chassis mount requirement and ensure adequate clearance for heat dissipation within the specified temperature limits. Verify compatibility with the 50/60 Hz frequency range of your power source.
