The Schaffner FN356-36-33 is a three-phase (Wye) EMC/EMI line filter designed for chassis mounting. It supports a rated current of 36 A and operates at voltages up to 440 VAC or 480 VAC, with a relative-to-neutral rating of 300 V and relative-to-phase of 520 V. The unit features a single-stage configuration with terminal block connections and functions within a temperature range of -25°C to 100°C. Certified by CSA, ENEC, and UR, it complies with RoHS3 standards.
Verify component authenticity through authorized TE Connectivity Schaffner channels. Confirm that the specific part number matches project requirements, noting that this model may be listed as obsolete or discontinued by some distributors. Ensure compatibility with existing chassis mounting hardware and terminal block wiring specifications before finalizing procurement decisions.
Select this filter when three-phase Wye configurations with neutral conductors are required. Ensure the operating voltage does not exceed 440 VAC or 480 VAC depending on the specific application standard. Verify that the 36 A current rating aligns with the load requirements and that the chassis mounting style fits the enclosure design constraints.
This component belongs to the FN 356 series, which represents industry-standard filter solutions for EMC compliance. Manufactured by Schaffner EMC Inc., now part of TE Connectivity, these filters are designed for general-purpose industrial applications requiring reliable noise suppression in three-phase power lines.
Public sources indicate this model is discontinued or obsolete. Verify availability of direct substitutes such as the FN3256H-36-33, ensuring identical electrical ratings and mounting configurations before substitution.
