Standard Performance Single-Phase
Filters FN350
Compact EMC/RFI Filter for Motor Drives
Compact filter solution for single-phase
motor drive applications
Approvals & Compliances
Industrial grade safety terminal blocks
Designed to meet EN 55011/14/22
Compliant with IEC 60950
Features and Benefits
Performance indicators
High component values optimized for common
and differential-mode attenuation in the lower
frequency range makes this filter ideal for a large
variety of single-phase motor drive applications
Supplied in a relatively small housing design with
safety terminal blocks for fast and easy
installation in primarily industrial environments
FN 350 also meets IEC 60950 requirements, thus
providing additional application flexibility
