3-138-343

Overview

The SCHURTER 3-138-343 is a three-phase (Delta) EMC/EMI power line filter module designed for industrial applications. It features a two-stage filtering architecture with a rated current of 230 A at 50/60 Hz and supports voltages up to 760 VAC. The unit utilizes terminal block connections with threaded M10 posts for secure mounting. Operating within a temperature range of -40°C to +100°C, it ensures reliable noise suppression in high-power electrical systems.

Feature Summary

• Two-stage EMC/EMI filtering architecture for effective noise attenuation
• High current capacity suitable for demanding industrial loads
• Robust mechanical design with threaded post terminal connections

Applications

• Industrial motor drives and power conversion systems
• Three-phase AC power distribution networks
• Heavy machinery requiring strict electromagnetic compatibility

Procurement Notes

Verify the specific voltage rating (760 VAC) and current capacity (230 A) against your system requirements before procurement. Confirm that the M10 threaded post terminals match your connection infrastructure. Ensure the operating temperature range aligns with your environmental conditions. Cross-reference the datasheet for precise physical dimensions and mounting specifications to guarantee proper integration into your equipment enclosure.

Selection Notes

Select this component when high-current three-phase filtering is required. The Delta configuration suits specific network topologies. Consider the thermal management capabilities given the high current rating. Evaluate the space constraints due to the module form factor. Compare leakage current specifications if sensitive downstream equipment is present. Ensure the installation environment supports the specified temperature extremes.

Part Context

This part belongs to Schurter's FMBC EP series of power line filter modules. These modules are engineered for robust performance in harsh industrial environments. The series emphasizes high current handling and effective EMI suppression. They are commonly used in applications where standard filters cannot meet the power density or noise reduction requirements.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing mounting hardware and terminal configurations when considering alternatives.
