3-138-290

Overview

The SCHURTER 3-138-290 is a three-phase delta EMC/EMI line filter module designed for industrial power conditioning. It features a single-stage filtering architecture with a rated current of 180 A at 50 to 60 Hz. The unit supports a voltage rating suitable for standard industrial AC systems and utilizes terminal block connections alongside threaded M6 posts for secure electrical interfacing. Constructed as a robust power line filter, it addresses electromagnetic interference in high-current applications.

Feature Summary

• Single-stage filtering topology for effective noise suppression
• High current capacity rated at 180 A
• Dual connection method using terminal blocks and threaded posts

Applications

• Industrial power distribution systems
• Three-phase motor drive protection
• Heavy machinery electromagnetic compatibility

Procurement Notes

Verify the specific voltage class and physical dimensions against your system requirements before ordering. Confirm that the M6 threaded post spacing aligns with your mounting infrastructure. Ensure the 180 A continuous current rating exceeds your maximum operational load to prevent thermal overload. Cross-reference the datasheet for derating curves applicable to your ambient temperature conditions.

Selection Notes

Select this component when a single-stage solution is sufficient for your EMI reduction needs. The combination of terminal blocks and threaded posts offers flexibility for different wiring strategies. Consider the physical footprint and weight implications for your enclosure design. Evaluate if the 180 A rating provides adequate margin for peak loads during startup or transient events.
