Overview
The FN3258-180-40 is a three-phase (Delta) EMC/EMI line filter module manufactured by TE Connectivity Schaffner. It features a single-stage design with a rated current of 180 A and operates at frequencies from DC to 60 Hz. The maximum AC voltage rating is 480 V. The unit utilizes terminal block termination for both input and output connections, supporting a 3-wire plus ground wiring configuration.
Feature Summary
- Compact and slim filter design optimized for minimal mounting space
- Exceptional attenuation performance in the 150 kHz to 30 MHz range
- Excellent saturation resistance up to rated current limits
Applications
- Industrial power distribution systems requiring EMI suppression
- Equipment installations with restricted physical mounting dimensions
- Three-phase Delta network filtering applications
Procurement Notes
Verify that the application requires a three-phase Delta configuration with terminal block terminations. Confirm the operating frequency does not exceed 60 Hz and the load current remains within the 180 A rating. Ensure the system voltage is compatible with the 480 V AC maximum specification before procurement.
Selection Notes
Select this component when space constraints are critical due to its slim profile. It is suitable for environments requiring high saturation resistance and significant attenuation between 150 kHz and 30 MHz. Ensure the wiring infrastructure supports terminal block connections rather than cable lugs or other termination types.
Part Context
This module belongs to the Schaffner FN 3258 series, which is characterized by ultra-compact designs for three-phase applications. The series provides robust electromagnetic compatibility solutions for industrial equipment where physical footprint and electrical performance must be balanced effectively.
Replacement Considerations
Consult official substitution guides for equivalent models within the FN 3258 series or alternative Schaffner lines that match the 180 A current rating and terminal block interface requirements.
