3-138-324

Overview

The SCHURTER Inc. model 3-138-324 is a three-phase (Delta) EMC/EMI power line filter module designed for industrial applications. It features a rated current of 50 A and supports AC voltages up to 520 VAC at operating frequencies of 50 Hz or 60 Hz. The unit utilizes a two-stage filtering architecture housed in a chassis-mount configuration with threaded M6 terminal posts for secure electrical connections. Key electrical specifications include a maximum leakage current of 9.42 mA and an operational temperature range spanning from -40°C to +100°C. Physical dimensions are approximately 130 mm in length, 110 mm in width, and 91 mm in height.

Feature Summary

• Two-stage EMC/EMI filtering architecture for effective noise suppression
• Chassis-mount design with robust M6 threaded terminal posts
• Wide operational temperature tolerance for harsh environments

Applications

• Industrial machinery power conditioning
• Three-phase motor drive systems
• Factory automation control panels

Procurement Notes

Verify the specific voltage rating and current capacity against your system requirements before integration. Confirm that the chassis-mount form factor and M6 terminal spacing align with your enclosure design. Ensure compliance with local electromagnetic compatibility regulations for your target market. Check for any recent component updates or packaging changes by consulting the official datasheet.

Selection Notes

Select this component when high-current three-phase filtering is required in a compact chassis-mounted format. The 50 A rating suits heavy-duty industrial loads. Consider the physical dimensions and thermal management needs given the +100°C maximum operating temperature. Compare against other Schurter FMBD series models if different mounting styles or current ratings are needed.
