Turn something old into a retrofit

A new level of performanceWith the retrofit solution from Siemens, you can exchange just the components that have been subjected to the most wear over their many years of reliable operation – instead of replacing the entire panel. These components generally consist of the switchgear truck and the circuit-breakers themselves.

Your advantages:Considerable cost savings ■

Simple “plug & play” replacement ■

Very short interruption of operation ■

Your system becomes practically maintenance-free ■

Quality for your safetyRetrofit solutions from Siemens have proven them-selves on the market for many years. In this case too, of course, the system solution – comprising the switchgear truck and the SION circuit-breaker – has been type-tested according to the currently valid standards IEC 62271-200 and IEC 62271-100. So you can be certain that these components of your sys-tem comply with the very latest safety standards.

Outstanding technology and performance

Customized solutionWhen you opt for retrofitting your 8B switchgear, you can request that the condition of the system and any modifications that have been carried out be assessed during an inspection. This ensures that the retrofit offers an exact replacement of the old components. Your advantage: replacing just a single component reduces lengthy approval proce-dures to a minimum.

Incidentally, Siemens offers this retrofit solution not only for its own products, but for equipment from other manufacturers. The new switchgear truck – including contact system, secondary equipment, interlocking, wiring, and low-voltage connectors – are adapted at Siemens so that the installation in your system is “plug & play.”

Retrofit with SIONThe central feature of the Siemens retrofit solution for the 8B switchgear is the SION vacuum circuit-breaker. This is one of the latest generation of circuit-breakers from Siemens, and is maintenance-free thanks to the high-quality materials used. Its high degree of reliability is grounded in Siemens vacuum circuit-breaker technology which has proven itself in millions of applications.

Comprehensive referencesSiemens SION retrofit solutions for 8B switchgear and for equipment from third-party manufacturers are in operation successfully throughout the world. If you are interested in a special solution, please contact your Siemens sales representative. Your representative will be happy to provide relevant reference projects and show you the retrofitting alternatives available for your system.

Weighing the individual advantages Siemens has now developed a retrofit solution especially for 8B switchgear. As switchgear assem-blies get older, the risk of undesirable operating incidents – such as high maintenance costs, unex-pected downtimes, and greater fire risk – increases while the spare parts supply situation becomes more difficult. With the new retrofit solution, Siemens offers you a low-cost alternative that allows you to continue using your proven switch-gear while profiting from the advantages of the latest generation of components.

Long-serving but still usable

SION retrofits for 8B switchgear are available immediately for a large number of ratings:

Ur [kV] Ir [A] Isc [kA] BIL [kV]

≤ 12 1,250 25 75

≤ 17.5 2,500 31.5 95

≤ 24 2,000 25 125

More than 40,000 Siemens medium-voltage panels of type series 8B have been operating successfully around the world for over 40 years. Many of them are still far from reaching the limits of their useful life. Nevertheless, in most power supply networks the technical requirements are now more stringent, and the original small-oil-volume circuit-breakers that were the core element of the switchgear are no longer state-of-the-art.
