Overview
The Schaffner FN3026HP-20-71 is a three-phase EMC/RFI line filter designed for DIN rail mounting. It features a Delta configuration with ring terminal inputs and outputs, rated for 20 A current and 520 VAC. The unit utilizes a single-stage filtering architecture within a plastic housing combined with a metal ground plate to ensure effective electromagnetic interference suppression while maintaining structural integrity in industrial environments.
Feature Summary
- DIN rail mounting design for streamlined integration
- Delta configuration with ring terminal connections
- Combined plastic housing and metal ground plate construction
Applications
- Industrial power distribution systems
- Three-phase equipment requiring EMI suppression
- DIN rail mounted control panels
Procurement Notes
Verify the specific ordering suffix ensures the correct terminal type and voltage rating. Confirm that the DIN rail mounting style matches the installation requirements. Check RoHS compliance status if required by project specifications. Ensure the 20 A current rating aligns with the load characteristics of the intended application circuit.
Selection Notes
Select this model when DIN rail mounting is preferred over chassis mounting. The HP series indicates high performance levels suitable for demanding EMC environments. Ensure the Delta configuration matches the three-phase system topology. Verify that the 520 VAC rating exceeds the maximum operating voltage of the connected equipment.
Part Context
This component belongs to the FN 3026 series, which offers DIN rail mounting options as an alternative to the chassis-mounted FN 3025 series. The HP designation typically denotes a higher performance grade within the product family. The series is engineered for robust electromagnetic compatibility in industrial power applications.
Replacement Considerations
The FN3026HL-20-71 is a documented variant within the same series offering different performance characteristics. Verify that any substitute maintains the 20 A rating and 520 VAC specification. Ensure the replacement supports the same Delta configuration and DIN rail mounting interface.
