Ultra-compact Low Leakage current EMC/EMI Filter
3-Phase Filters with Neutral FN355
Ultra-compact Low Leakage current EMC/EMI Filter
- Ultra-compact four-wire filter for applications lacking space
- Exceptional low operating leakage current
- Equally suitable for star and delta power networks
Features and Benefits
The FN 355 family of three-phase and neutral line filters provides a cost-effective interference suppression solution for a wide variety of applications
Available in four versions, with current ratings from 3 to 20 A, the filters employ a single-stage four-wire LC circuit with saturating resistant chokes, and have a very low operational leakage current
FN 355 filters are contained within an extremely compact metal housing, making them ideal for use in situations where space is at a premium
Typical Applications
Office equipment
Medical equipment
General purpose four-wire filtering
Applications with tight space conditions
