3-138-291

Overview

The SCHURTER 3-138-291 is a three-phase (Delta) EMC/EMI power line filter module designed for industrial applications. It features a rated current of 230 A at AC voltages between 50 and 60 Hz. The unit utilizes a single-stage filtering architecture with terminal block connections and threaded M6 posts for secure mounting. Key electrical specifications include a maximum leakage current of 13.1 mA. The device operates within a temperature range of -40°C to +100°C and supports chassis mounting configurations.

Feature Summary

• Provides effective electromagnetic interference suppression for three-phase Delta systems
• Utilizes robust terminal block interface with threaded M6 posts for reliable connectivity
• Engineered for high-current industrial environments with extended thermal tolerance

Applications

• Industrial machinery power conditioning
• Three-phase motor drive protection
• Heavy-duty manufacturing equipment EMC compliance

Procurement Notes

Verify the specific Delta configuration requirement against your system topology before procurement. Confirm that the M6 threaded post terminals align with your existing busbar or cable lug specifications. Ensure the ambient operating environment remains within the specified -40°C to +100°C range to maintain performance integrity and safety certifications.

Selection Notes

Select this component when a high-current, single-stage solution is required for Delta-connected three-phase networks. The 230 A rating suits heavy industrial loads where standard filters may be insufficient. Consider the chassis mount style and physical dimensions during panel layout planning to ensure adequate clearance for heat dissipation and maintenance access.
