FIELD: overvoltage protection.
SUBSTANCE: invention relates to devices for reducing the potential difference between rails and ground. A voltage limiter with overvoltage protection contains an insulating shell closed from above by the first contact plate with the first contact terminal and closed from below by the second contact plate with the second contact terminal. The limiter is made of two triggering semiconductor elements and a protective element connected in parallel. The protective element is located between two inner plates. Triggering semiconductor elements are connected to an electronic control device and contact terminals by means of auxiliary lines. The first triggering semiconductor element is located between the first inner plate and the first contact plate. The second triggering semiconductor element is located between the second inner plate and the second contact plate. The first contact plate and the second inner plate are fastened using two electrically conductive first support elements. The second contact plate and the first inner plate are fastened using two electrically conductive second support elements.
EFFECT: providing effective protection against pulse overvoltage.
