3-138-329

Overview

The SCHURTER 3-138-329 is a three-phase (Delta) EMC/EMI power line filter module designed for industrial applications. It features a rated current of 230 A and operates at voltages up to 520 VAC with frequencies of 50 Hz or 60 Hz. The unit utilizes a two-stage filtering architecture and employs terminal block connections with threaded M10 posts for secure mounting. Physical dimensions include a length of 130 mm, width of 110 mm, and height of 91 mm. It supports an operating temperature range from -40°C to +100°C and maintains a leakage current of 9.42 mA.

Feature Summary

• Two-stage EMC/EMI filtering architecture for effective noise suppression
• Robust terminal block connection system with threaded M10 posts
• High current capacity suitable for demanding industrial power systems
• Wide operational temperature tolerance for harsh environments

Applications

• Three-phase AC/DC power conditioning systems
• Industrial machinery requiring EMI/EMC compliance
• Power distribution units in manufacturing facilities

Procurement Notes

Verify the specific voltage rating and current requirements against your system specifications before procurement. Confirm that the M10 threaded post terminals match your existing busbar or cable lug configurations. Ensure the physical footprint fits within the designated enclosure space. Check for any regional supply restrictions or discontinuation notices associated with this part number.

Selection Notes

Select this component when a high-current, two-stage solution is required for Delta-connected three-phase networks. Compare the 230 A rating against peak load demands to ensure adequate headroom. Consider the thermal management capabilities given the +100°C maximum operating temperature. Evaluate the screw mount installation style against available panel space and accessibility for maintenance.

Part Context

This model belongs to Schurter's FMBC series of power line filter modules. These components are engineered for integration into larger electrical assemblies where significant electromagnetic interference must be mitigated. The design prioritizes durability and high-performance filtering in compact industrial enclosures.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing mounting hardware and terminal interfaces if considering alternative manufacturers.
