3-138-308

Overview

The SCHURTER Inc. model 3-138-308 is a three-phase AC/DC power line filter module designed for industrial applications. It operates at a rated voltage of 520 VAC and supports a current rating of 36 A. The unit features an inductive filtering stage and utilizes screw clamp termination methods for secure electrical connections. Designed for panel mounting, the component functions within a temperature range of -40°C to +100°C. Its physical dimensions include a height of 91 mm and a length of 130 mm, with a leakage current specification of 9.42 mA at operating frequencies of 50 Hz and 60 Hz.

Feature Summary

• Provides electromagnetic interference suppression through a single-stage inductive filter design for three-phase systems.
• Ensures reliable electrical connectivity via screw clamp termination interfaces suitable for robust industrial wiring.
• Engineered for high thermal stability, maintaining operational integrity across extreme ambient temperatures.

Applications

• Industrial machinery power distribution
• Three-phase motor drive protection
• Heavy-duty equipment EMC compliance

Procurement Notes

Verify the specific part number against official Schurter documentation to confirm compatibility with your system's voltage and current requirements. Ensure that the screw clamp termination type matches your existing wiring infrastructure. Confirm that the environmental temperature ratings align with your installation site conditions. Cross-reference the physical dimensions to validate panel space availability before finalizing procurement decisions.

Selection Notes

Select this component when a dedicated three-phase filter is required for 520 VAC systems carrying up to 36 A. Consider the screw mount style if PCB or terminal block integration is not preferred. Evaluate the thermal performance specifications against local ambient heat sources. Compare the leakage current values against sensitive downstream equipment limitations to ensure safe operation without nuisance tripping.

Part Context

This component belongs to the FMAD NEO series of power line filters manufactured by Schurter. The series focuses on providing effective noise attenuation for industrial power networks.
