The horizontal double-break disconnector type SSBIII consists of three poles. Each pole consists of a frame, two supporting insulators at each end and one rotating insulator in the center, on which the main blade is mounted.

   The main blade consists of two fixed contacts, mounted on the supporting insulators, and a moving blade mounted on the rotating insulator. The main contacts are installed inside the main blade. They are made of copper, with a silver-plated surface. Each contact finger is provided with stainless steel springs to ensure reliable contact pressure. The contacts are self-cleansing, which makes the disconnector suitable for installation in areas with severe climatic conditions. Depending on the voltage rating, anti-corona shields will be provided.

    The SSBIII disconnectors comply with publication IEC 62271-102; IEC 62271-1 and most other national regulations.
