Schurter FMBC EP 3-Phased Double Stage Filters

Schurter FMBC EP 3-Phased Double Stage Filters provide high performance in a compact package, ideally suited for space-constrained machine and industrial plant construction. Versions with high nominal voltages are particularly suited for a wide field of applications. The almost cuboidal design makes optimum use of the space in the housing. A double-stage filter built with high-quality components (generously sized film capacitors, chokes with highly permeable cores) provides exceptional broadband filter attenuation. The double-stage filters are also appropriate for applications with particularly high EMC emissions, as is frequently encountered in machine operations. Typical applications include automatic production, motor drives, and industrial plant machinery. These powerful filters are also ideal for modern frequency inverters for motor control.

The FMBC EP devices feature screw terminals for absolutely safe wiring. A metal flange provides an excellent earth connection when screwed to the chassis. Standard types can be used over a wide temperature range from -40°C to +100°C. The filters are designed for currents from 16A to 230A at an ambient temperature of +50°C. They have both ENEC and cURus approval and are recommended for applications up to 520VAC or even 760VAC. The standard versions are designed for industrial applications with leakage currents <4mA. Special variations, rated with <1mA leakage current, are available for applications where minimizing leakage current is critical.
