Schurter recently launched the FMBC EP double-stage filter line for three-phase systems. The high-performance filter’s compact size makes it suitable for space-constrained machine and industrial plant construction, according to Santa Rosa, Calif.-based Schurter. Versions with high nominal voltages are particularly suited for a wide field of applications, the company added.
The FMBC EP series features screw terminals for safe wiring. Standard types can be used over a wide temperature range from -40°C to 100°C. The filters are designed for currents from 16 A to 230 A at an ambient temperature of 50°C. They have both ENEC and cURus approval and are recommended for applications up to 520 VAC or even 760 VAC. The standard versions are designed for industrial applications with leakage currents <4 mA. Special variations, rated with <1 mA leakage current, are available for applications where minimizing leakage current is critical.
Schurter downsized its EMC filter range from previous generations. The new, almost cuboidal design, makes optimum use of the space in control cabinet housing. The double-stage filter is built with generously sized film capacitors and permeable-core chokes to provide exceptional broadband filter attenuation.
The double-stage filter family is also appropriate for applications with particularly high EMC emissions, as is frequently encountered in machine operations, according to Schurter. Typical applications include automatic production, motor drives and industrial plant machinery.
