Overview
The SCHURTER 3-138-350 is a three-phase AC/DC power line filter designed for industrial applications. It features a two-stage filtering architecture with a rated current of 25 A and a maximum voltage rating of 520 VAC. The unit operates within a temperature range of -40°C to +100°C at frequencies of 50 Hz or 60 Hz. Physical dimensions are 121 mm in length, 110 mm in width, and 91 mm in height. It utilizes screw clamp termination via M6 threaded posts and supports chassis mounting.
Feature Summary
- Two-stage EMC/EMI filtering architecture for enhanced noise suppression
- Chassis mount design with screw clamp termination using M6 threaded posts
- Rated for 25 A continuous current at 520 VAC
- Operational stability across a wide temperature range from -40°C to +100°C
Applications
- Industrial power conditioning systems
- Three-phase AC/DC equipment requiring EMI suppression
- Chassis-mounted power line filtration units
Procurement Notes
Verify the specific datasheet version for the 3-138-350 to confirm compliance with current RoHS standards and exact terminal specifications. Ensure that the M6 threaded post termination matches the existing chassis infrastructure. Confirm that the 25 A current rating and 520 VAC voltage limits align with the target system's electrical requirements before integration.
Selection Notes
Select this component when a two-stage filtering solution is required for three-phase systems operating up to 25 A. The chassis mount style and M6 termination dictate mechanical compatibility. Verify that the 520 VAC rating meets the phase-to-phase voltage requirements of the application environment.
Part Context
This part belongs to the Schurter FMBD EP series of power line filters. These components are engineered for robust industrial environments, providing reliable electromagnetic interference reduction. The series typically offers various current ratings and mounting configurations to suit different power distribution needs.
Replacement Considerations
The 3-138-373 is a documented substitute offering identical 25 A current rating and two-stage filtering characteristics. Verify mechanical fit and terminal alignment when considering alternative models within the same product family.
