SCHURTER’s FPBB RAIL is an extraordinary slim, double-stage, single-phase filter measuring only 25 mm in width. The attractive space-saving design integrates an optional fuse holder or circuit breaker. Additionally, an overvoltage varistor is available in all three variations.

Space can be a scarce commodity on a panel, particularly panel designs in control cabinets for industrial machinery. Densely populated interference generating components, such as switching power supplies or inverters, can further complicate design as high-performance filters are required to reach CE conformity. These filters can be large and occupy premium space on the DIN rail. SCHURTER provides a solution with the FPBB RAIL, a two-stage filter offering a very high EMI attenuation in an ultra-slim, space-saving housing.

Typical areas of application for the FPBB RAIL are industrial or machine controls, where downsizing and possible relocation of the control cabinet to a more accessible area can be realized. A backplane screw mount version is also available for further flexibility in design. The powerful, slim filters are also ideal for medical equipment according to IEC/UL 60601-1 and ICT equipment according to IEC/UL 60950, offering low leakage or standard current options. Further features include cage clamp terminals for particularly efficient, fast wiring.

The FPBB RAIL is designed for currents from 1 A to 16 A with a maximum of 125/250 V_AC and 250 V_DC according to IEC and UL/CSA standards. The series is ENEC and cURus approved. The filter version can be used over a wide temperature range from -40°C to +100°C. Versions with fuse holder and overvoltage protection operate over a temperature range of -40°C to +85°C, while those with a circuit breaker are rated for a range of -5°C to +60°C.
