3-138-321

Overview

The SCHURTER Inc. model 3-138-321 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 16 A and operates at frequencies between 50 Hz and 60 Hz. The unit supports a voltage rating of 520 VAC and functions within an ambient temperature range of -40°C to +100°C. Installation is achieved via chassis mounting using terminal blocks or threaded M6 posts, ensuring secure electrical connections in demanding environments.

Feature Summary

• Two-stage filtering architecture for enhanced noise suppression
• Chassis mount design with terminal block or threaded post termination
• Operates reliably in extreme temperatures from -40°C to +100°C

Applications

• Industrial machinery control panels
• Three-phase power distribution systems
• EMC compliance for sensitive electronic equipment

Procurement Notes

Verify the specific datasheet version for your region, as availability may vary by distributor. Confirm that the M6 threaded post termination matches your panel hardware. Ensure the 16 A current rating aligns with your system's maximum load requirements before finalizing procurement.

Selection Notes

Select this component when a compact, high-performance two-stage filter is required for three-phase Delta systems. It is suitable for applications needing robust thermal performance up to 100°C. Consider the chassis mount style if space constraints preclude DIN rail installation.
