The FN258HVIT-42-33 is a three-phase EMC/EMI line filter manufactured by Schaffner. It supports a rated current of 42 A and operates at frequencies from DC to 60 Hz. The unit utilizes a two-stage filtering architecture with terminal block connections for chassis mounting. Physical dimensions are 300 mm in length, 70 mm in width, and 185 mm in height, with an approximate weight of 3 kg.
Verify the specific datasheet version and compliance certificates directly with TE Connectivity or authorized distributors before procurement. Confirm that the terminal block configuration matches the installation requirements. Ensure the operating environment temperature range aligns with the component specifications to maintain performance integrity.
Select this model when high current capacity and robust EMI suppression are required for three-phase AC applications. Consider the physical footprint and chassis mounting constraints during system integration. Evaluate the leakage current characteristics against safety standards applicable to the final equipment design.
This component belongs to the FN258 series of power line filters designed for demanding industrial environments. The HV designation indicates high-voltage capability, while IT suggests specific insulation or terminal configurations. It serves as a critical interface for protecting sensitive electronics from conducted interference in heavy-duty power distribution networks.
