3-138-294

Overview

The SCHURTER Inc. 3-138-294 is a single-stage EMC/EMI power line filter module designed for three-phase AC systems. It features a rated current of 36 A and a voltage rating of 520 VAC. The unit operates within a frequency range of 50 to 60 Hz and utilizes chassis mount installation with terminal block or threaded post (M6) connections. It exhibits low leakage current characteristics suitable for industrial applications.

Feature Summary

• Single-stage electromagnetic interference filtering architecture
• Low leakage current design for safety compliance
• Three-phase system compatibility

Applications

• Industrial equipment power conditioning
• Three-phase motor drive protection
• EMC compliance in manufacturing machinery

Procurement Notes

Verify the specific datasheet version for exact attenuation curves and thermal derating information. Confirm mechanical mounting dimensions against the enclosure design. Ensure input/output wiring matches the M6 threaded post or terminal block specifications. Validate that the 36A continuous current rating aligns with the load requirements under expected ambient temperatures.

Selection Notes

Select this component when single-stage filtration is sufficient for the application's noise profile. Consider the 36A current capacity relative to peak loads. Evaluate the chassis mount form factor against available panel space. Compare leakage current limits against sensitive downstream equipment requirements.

Part Context

This component belongs to the FMAC NEO series, which focuses on clean and safe power supply solutions. Schurter manufactures these filters to meet international standards for circuit protection and electromagnetic compatibility in demanding industrial environments.

Replacement Considerations

Check for direct substitutes within the FMAC NEO series with adjusted current ratings. Verify cross-compatibility with other single-stage three-phase filters from different manufacturers by comparing voltage, current, and mounting dimensions.
