FMBC EP 3-Phase Mains Filter
• Compact design with minimal footprint
• Double-stage filter with high attenuation
• Variants for high voltage applications
• Wide temperature range

Schurter introduces the FMBC EP double-stage filter family for 3 phase systems. Thanks to its particularly compact dimensions and high performance, the new filter series is ideally suited for the tight space conditions in today’s machine and industrial plant construction. Due to versions with high nominal voltages, a particularly wide field of applications is possible.

Space is scarce in control cabinets for industrial applications in the 3-phase range. Schhurter has addressed this problem with another complete filter redesign, which is much more compact than previous generations. The new, almost cuboidal design makes optimum use of the space in the housing. Thanks to a double-stage filter and the use of the highest quality components (generously dimensioned film capacitors, chokes with highly permeable cores), the new development shines with exceptional broadband filter attenuation.

Suitable for High EMC Emissions
The double-stage filter family is therefore also appropriate for applications with particularly high EMC emissions, as is frequently encountered in industry. Typical applications include machines and systems for automatic production, motor drives and industrial plant machinery. These powerful filters are also the first choice for modern frequency inverters for motor control.

Mounting
The FMBC EP series features screw terminals for absolutely safe wiring. Thanks to the metal flange, an excellent earth connection is ensured when screwed to the chassis.

Wide Temperature and Voltage Range
The 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.

Leakage Current
The standard versions are designed for industrial applications with leakage currents <4 mA. Special variants with leakage currents <1 mA are available for leakage current critical applications.

Applications
• Industrial equipment, machines
• Robotics
•Motor drive applications
•Machine tools
• Energy inverters

The completely redesigned FMBC EP models are the ideal replacement for all types of Schurter FMBC and FMBC NEO filters. They offer identical performance with significantly reduced dimensions and weight.

Schurter Logo1.jpg

Single Phase Block Filter with Excellent Performance
• Ultra compact double stage filter
• Excellent symmetrical and asymmetrical attenuation
• Very broad band attenuation
• Completely closed steel housing

Schurter completes its portfolio of ultra-compact single-phase filters with a new generation of particularly high-performance thanks to a double stage filter design. FMBB EP is the name of the latest member in the completely closed steel housing.

Ever more powerful and at the same time ever more compact design – these are the requirements for state-of-the-art electronic devices. The filters of the FMBB EP family are particularly suitable wherever such equipment is confronted with stubbornly high EMI interference signals. Highly clocked semiconductors generate increasingly strong interference frequencies. This massively increases the requirements for compliance with EMC. Typical applications include test and measurement equipment, professional kitchen equipment, medical and critical industrial applications.

Identical Housing Dimensions
The new filters use the same housings as the proven FMBB NEO filter series. These housings are spot welded, thus completely closed, resulting in significantly improved attenuation behavior. Thanks to topquality components (generously dimensioned film capacitors, chokes with highly permeable cores), an exceptionally broad-band attenuation is achieved.

Mounting
The FMBB EP filter series has 6.3 x 0.8 mm plug-in connections or threaded connections for quick and easy wiring. Thanks to a metal flange, excellent ground connection is ensured when screwed to the chassis.

Wide Temperature Range
The standard versions can be used over a temperature range from -40 °C to 100 °C. The filters are designed for currents from 1 A to 36 A at an ambient temperature of 40 °C. They have ENEC and cURus approval and are recommended for applications up to max. 250 VAC.

Leakage Current
There are versions with different leakage currents available for different applications: the standard version with 0.9 mA to 3.8 mA, for medical technology ≤ 5 µA or ≤ 80 µA.

Leakage Current
Versions with different leakage currents are available for various applications: for industrial ≤ 3 mA, standard ≤ 0.5 mA and for medical technology ≤ 5 µA.

“High Performance” Version
Although the new filter family is already equipped with very high-quality components, an even stronger filter effect might be required for particularly demanding applications. This is where the “High Performance” versions come into play. Thanks to compact chokes with particularly high inductance and a larger X capacitor, both symmetrical and asymmetrical interference can be suppressed even more effectively.

The completely newly developed FMAD CP filters are the ideal replacement for the SCHURTER FMW465, offering at least the same, but rather higher performance at lower weight.
