3-138-284

Overview

The SCHURTER 3-138-284 is a three-phase (Delta) EMC/EMI power line filter module designed for industrial applications. It supports a rated current of 25 A at 50 to 60 Hz with a voltage rating of 520 VAC. The unit features a single-stage filtering configuration and utilizes screw clamp terminal connections via M6 threaded posts. It employs chassis mounting for secure installation. The device operates within a temperature range of -40°C to +100°C.

Feature Summary

• Provides single-stage electromagnetic interference suppression for three-phase delta systems
• Utilizes robust screw clamp terminal blocks with M6 threaded posts for reliable electrical connections
• Engineered for direct chassis mounting in industrial environments

Applications

• Industrial machinery requiring EMI/EMC compliance
• Three-phase power distribution systems
• Equipment sensitive to electromagnetic interference

Procurement Notes

Verify the specific phase configuration requirement, as this model is designated for Delta connections. Confirm that the operating environment temperature remains within the specified -40°C to +100°C range. Ensure the mounting surface accommodates the chassis mount style and that the M6 terminal posts align with the available wiring infrastructure. Cross-reference the 25 A current rating against peak load requirements to prevent overload conditions during operation.

Selection Notes

Select this component when a single-stage solution for three-phase delta networks is required. It is suitable for applications needing 25 A capacity at 520 VAC. Consider the chassis mounting style and M6 terminal interface for integration. Evaluate the thermal performance limits if the ambient temperature approaches the maximum operational threshold of 100°C.

Part Context

This component belongs to Schurter's power line filter modules series, specifically engineered for industrial-grade electromagnetic compatibility. It addresses noise suppression needs in three-phase systems where standard filters may not suffice for delta configurations. The design prioritizes durability and straightforward installation via chassis mounting.
