General Purpose EMC/EMI Line Filter
3-Phase Filters with Neutral FN356
General Purpose EMC/EMI Line Filter
NOT FOR NEW DESIGN
- Three-phase and neutral line filter for general four-wire filtering tasks
- Choice of connection style
- Low operating leakage current
- Compliant with IEC 60950
- Suitable to meet EN 55011/14/22
Features and Benefits
FN 356 represents the industry standard filter solutions for EMC compliance on three-phases and the neutral conductor, providing high attenuation of both symmetrical and asymmetrical interference
Choice of connection style is offered for an application-specific filter selection
Solid touch-safe terminal blocks (-29, -33, -34 versions) offer a generous contacting cross section and contribute to overall safety (IP 20)
Used as a mains input filter, FN 356 filters increase the conducted immunity and thus contribute to system reliability
Design compliance with IEC 60950 provides additional application flexibility
