Overview
The SCHURTER Inc. model 3-138-333 is a three-phase (Delta) EMC/EMI line filter module designed for industrial power conditioning applications. It features a two-stage filtering architecture to suppress electromagnetic interference across power lines. The unit supports a rated current of 50 A at frequencies between 50 and 60 Hz, with a maximum voltage rating of 520 VAC. Termination is achieved via terminal block connections utilizing threaded posts sized M6. This component is engineered for robust performance in demanding electrical environments requiring effective noise reduction.
Feature Summary
- Two-stage filtering architecture for enhanced EMI suppression
- Designed specifically for three-phase Delta power configurations
- Utilizes terminal block termination with M6 threaded posts
Applications
- Industrial machinery power conditioning
- Three-phase motor drive systems
- Factory automation equipment
Procurement Notes
Verify the specific datasheet version for the 3-138-333 to confirm exact attenuation curves and physical dimensions prior to integration. Ensure that the M6 threaded post termination method aligns with the system's wiring infrastructure. Cross-reference the 50 A current rating against peak load requirements to prevent thermal overload during operation.
Selection Notes
Select this module when a two-stage solution is required for three-phase Delta networks operating up to 520 VAC. The 50 A rating suits moderate-power industrial loads. Consider the M6 terminal interface compatibility with existing busbar or cable arrangements. Evaluate space constraints as this is a modular unit rather than a compact inline filter.
Part Context
This component belongs to Schurter’s FMBC EP series of power line filters. These modules are part of a broader family of EMC solutions designed for industrial power distribution. The series emphasizes high-current handling capabilities and modular installation options for scalable power quality management in heavy-duty applications.
