High Electrical Loads

At high electric loads that usually occur in power engineering devices, the switching phenomena are mostly related to arc formation. For most applications, the management of the switching arc is the key problem. Depending on the device, type different requirements are dominant which influence the selection of the contact material. Similar to those in communications engineering, issues related to the switching characteristics and current path have to be considered.
