3-137-020

Overview

The Schurter 3-137-020 is a single-phase AC power line filter from the FMAB NEO series, designed for mains connection. It features an integrated PE choke and supports a rated current of 4A at 250VAC. The unit utilizes M80 terminal connections and provides EMI suppression to meet IEC/EN 61000-3-2 harmonic emission standards. Certified under UL, CSA, VDE, and CQC, it operates within a temperature range of -25°C to +85°C. The housing is constructed from thermoplastic material, ensuring compliance with RoHS directives.

Feature Summary

• Integrated PE choke for enhanced common-mode noise attenuation
• Compliance with IEC/EN 61000-3-2 harmonic emission limits
• M80 terminal interface for secure electrical connection
• Thermoplastic enclosure suitable for panel mounting

Applications

• Medical equipment power supplies
• Industrial control systems
• Information technology hardware
• Audio and video processing units

Procurement Notes

Verify that the specific application requires the M80 terminal configuration and 4A current rating. Confirm that the integrated PE choke aligns with the system's grounding topology. Ensure the operating environment remains within the specified -25°C to +85°C thermal limits. Cross-reference required certifications such as UL or VDE against regional regulatory mandates before finalizing procurement.

Selection Notes

Select this component when harmonic distortion reduction per IEC 61000-3-2 is mandatory. Choose the M80 terminal style if screw or clamp connections are preferred over PCB mounting. Consider the physical dimensions and thermal dissipation requirements relative to the enclosure design. Evaluate the need for integrated chokes versus external filtering solutions based on space constraints.
