Three-phase EMC filters NFK855 from FEAS
Your key to interference-free production
Interference-free industrial plants despite EMC challenges
n modern industrial plants, milliseconds determine productivity. However, EMC interference in three-phase networks causes millions in costs every year due to unplanned downtime, data loss in control systems or premature wear of drive components.
The NFK855-20A31 three-phase EMC filter from FEAS offers a reliable solution here, combining innovative filter technology with robust construction:
• High-performance attenuation: 40 dB insertion loss over 150 kHz–30 MHz thanks to optimised LC combination
• Robust EMC shielding according to EN 133200 for interference-free networks in manufacturing environments
• Safety according to: VDE, EN 602368-1, UL1283 and CSA-C22.2 for worldwide use
• Aluminium housing with integrated heat dissipation – even with continuous loads up to 20 A
• Plug-and-play installation via top-hat rail (DIN 46277) or direct mounting
• Tropicalised full encapsulation in epoxy resin for use in harsh environments
Practical application examples
A medium-sized automotive supplier reduced EMC-related downtime by 72% after retrofitting 23 NFK855-20A31 filters in its press line. The filters eliminate interference from frequency converters and ensure communication between PLC controllers and IoT sensors.
