3-138-352

Overview

The SCHURTER 3-138-352 is a three-phase AC/DC power line filter designed for industrial applications. It features a two-stage filtering configuration to effectively suppress electromagnetic interference (EMI) and radio frequency interference (RFI). The unit supports a continuous current rating of 50 A and operates at voltages up to 520 VAC, with compatibility for 760 VAC systems. It utilizes screw clamp termination methods for secure electrical connections. The device is rated for operation within a temperature range of -40°C to +100°C and has a leakage current of 9.42 mA.

Feature Summary

• Two-stage EMI/RFI suppression architecture
• Screw clamp terminal connection method
• Chassis mount installation style

Applications

• Industrial machinery power supply protection
• Three-phase motor drive input filtering
• Medical equipment power conditioning

Procurement Notes

Verify the specific voltage rating requirements against the datasheet, as the component supports both 520 VAC and 760 VAC configurations depending on the exact variant. Confirm that the mounting hardware matches the chassis specifications. Ensure the ambient operating temperature does not exceed the maximum limit of +100°C during installation planning.

Selection Notes

Select this model when high-current three-phase filtering is required in compact enclosures. The screw clamp termination simplifies wiring compared to soldered options. Consider the physical dimensions of 130 mm length and 91 mm height during panel layout design to ensure adequate clearance for heat dissipation and maintenance access.

Part Context

This component belongs to the FMBD EP series from SCHURTER, which specializes in robust power line filters for demanding environments. The series is engineered to meet stringent international safety and EMC standards, providing reliable noise attenuation for sensitive electronic loads connected to three-phase power networks.

Replacement Considerations

Cross-reference part numbers such as 3-138-351 or 3-138-353 for variants with different current ratings or voltage tolerances. Verify mechanical footprint compatibility before substitution to avoid re-engineering the mounting bracket.
