SIEMENS RAIL ELECTRIFICATION DC TYPES 3EB2 AND 3EB3- SURGE ARRESTERS FOR RAILWAY APPLICATIONS

3EB2 & 3EB3 Surge Arresters: Siemens has been designing and manufacturing medium- and high-voltage surge arresters for standard and special applications since 1925. We have produced surge arresters for railway systems for over 80 years. Continuous research and development, extensive know-how, and global experience give Siemens surge arresters a leading position in the overvoltage protection market. Their uncompromising quality ensures a long service life and reliability in every application.

Our surge arresters for railway applications protect every part of a rail system, from traction substations, transmission lines, cables, and catenary systems to rail vehicles for local, long distance, and high-speed services up to 420 km/h. We offer several surge arresters for AC and DC railway applications up to 45 kV.

3EB2 and 3EB3 – Surge arresters with silicone rubber housing for use on traction vehicles and for fixed installation in DC systems; A1 and A2 application. The 3EB2 is DC-B classified, the 3EB3 is DC-C classified.

Rail electrification DC types 3EB2 and 3EB3

The 3EB2 and 3EB3 silicone-housed surge arresters were developed specifically for overvoltage protection in DC systems in accordance with the VDV A1-A2 application.

The 3EB3 has a DC-C classification and an extremely high energy absorption capacity.
