摘要

The surge arrester has a varistor arrangement comprising varistor modules (3a-3d, 5a-5c) connected with each other over an electrically conductive connection, which is secured by a coupling arrangement. The coupling arrangement comprising coupling elements (6a-6d, 7a-7d) is a part of an output current path, and each of the coupling elements is arranged at the varistor modules. The varistor modules are connected with each other with a rigid angle by the coupling arrangement.
