## **Compact Line Filter for Industrial Machinery/Equipment** 

## 

**Compact, space-saving design, optimized for industrial machinery** 

**Combines high attenuation performance with low leakage current Performance according to the machine tool standard EN 50370-1 Increases also the immunity if operated directly on the mains input** 

## ee **Approvals** 

## **Features and benefits** 

**An extremely compact and light weight filter design with a „cubic“ shape, requiring minimum mounting space and thus taking the constructional conditions on the mains input of machinery into account Simple and time-saving installation with good accessibility for automatic and hand tools** 

**Solid, touch-safe terminal blocks offering sufficient contacting cross section according to the EN 602041 installation standard, which is very common in industrial applications** 

**As a mains input filter for three phases and neutral line, FN 3256 ensures the compliance with the new product family standard for machine tools in mainly industrial environments EN 50370-1. Further, its use will also increase the conducted immunity of the entire installation significantly** 

**FN 3256 provides the attenuation performance to meet the requirements of various machine tools with up to 8 driving axes with ~10 m of motor cable each** 

## **Technical specifications** 

- **Maximum continuous operating voltage 3x 520/300 VAC (480 VAC +10% possible) Operating frequency dc to 60 Hz Rated currents 8 to 160 A @ 50 °C High potential test voltage P –> E 3000 VDC for 2 sec P –> P 2250 VDC for 2 sec** 

- **Protection category IP20 Overload capability 4x rated current at switch on, 1.5x rated current for 1 minute, once per hour** 

- **Temperature range (operation and storage) -25 °C to +100 °C (25/100/21) Flammability corresponding to UL 94 V-2 or better Design corresponding to UL 1283, CSA 22.2 No. 8 1986, IEC/EN 60939 MTBF @ 50°C/400V (Mil-HB-217F) >410,000 hours** 

**For easy selection and application, the filter current ratings are aligned with common fuse values** 

## **Typical applications** 

**Mainly industrial equipment, machinery, machine tools and diverse process auto- mation systems with three-phase and neutral electricity supply. Further, these filters are suitable for power supplies, highpower office equipment and further applications, where efficient interference suppression on three phases and the neutral line is required and where space is critical. Because of the very low leakage current, FN 3256 can even be used for some medical devices.**
