3-Line/4-Line Filters

TDK 3-Line / 4-Line EMC filters are designed as easy-to-install power line filters in 3-phase systems. The lightweight design is optimized for operation under full load. Different filters are available with a variety of connection types, a broad range of rated current and voltage as well as different attenuation levels. EPCOS 3-Line/4-Line EMC Filters are available in compact, ultra-compact, and cost-effective versions with voltages up to 760/440VAC and current ratings up to 2500A. The compact and cost effective versions feature busbar terminals and the ultra-compact versions feature finger-safe terminal blocks. TDK 3-Line/4-Line Filters are especially well-suited for frequency converters in motor drives, elevators, wind farms, and power supplies.
