After

Vacuum circuit breakers for generators. Type tests as specified in IEC 62271-100 are performed as a rule for all Siemens circuit breakers. Generator circuit breakers are additionally tested in accordance

Siemens’ comprehensive portfolio of outdoor vacuum switching devices has been especially designed for a wide variety of applications and climatic conditions. Thus, type-tested reliability as well as long electrical life and mechanical robustness minimize operation cost of medium-voltage grids.

Vacuum interrupters are the centerpiece of our medium-voltage components. The hermetically sealed vacuum contact gap keeps the switching characteristics of the interrupters constant throughout their entire lifecycle. Special contact materials made by Siemens ensure that our vacuum interrupters offer absolutely top
