3-138-353

Overview

The SCHURTER 3-138-353 is a three-phase AC/DC power line filter module designed for industrial applications. It supports a rated current of 64 A and operates at voltages up to 520 VAC. The unit provides two-stage filtering with a leakage current of 9.42 mA at 50 Hz or 60 Hz frequencies. Constructed for screw mount installation using screw clamp termination, it features an M6 threaded post terminal interface. The component measures 130 mm in length and 91 mm in height, functioning reliably within a temperature range of -40°C to +100°C.

Feature Summary

• Provides two-stage electromagnetic interference suppression for three-phase systems
• Utilizes screw clamp termination with M6 threaded posts for secure connection
• Designed for direct screw mounting on standard surfaces

Applications

• Industrial power distribution systems requiring EMI mitigation
• Three-phase AC/DC equipment input stages
• Heavy machinery power supply conditioning

Procurement Notes

Verify the specific manufacturing date code against project requirements, as electronic components may undergo lifecycle changes. Confirm that the physical dimensions and terminal spacing match the existing enclosure design before finalizing procurement. Ensure the operating environment stays within the specified -40°C to +100°C range to maintain performance integrity and safety compliance.

Selection Notes

Select this model when a robust, high-current solution is needed for three-phase noise reduction. The 64 A rating suits heavy loads, while the low leakage current minimizes ground fault risks. Consider the screw mount style if PCB integration is not required. Verify that the 520 VAC rating aligns with the system voltage to prevent insulation breakdown under normal operating conditions.
