Solid-state breakers (SSBs) for switching capacitors up to 11 kV are advanced devices used in HV applications in place of breaker like VCBs. Those are available upto 4.0 MVAr capacitor banks and multiples thereof.

Typically, thyristors, IGBTs (Insulated Gate Bipolar Transistors), or MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) are used as the main switching elements. Solid-state breakers can switch capacitor banks used for power factor correction in industrial and utility applications.
