Abstract:
1. An electrical installation with circuit integrity of an electric through line under fire impact, comprising: the through line; plural consumer devices, wherein the consumer devices have a lower circuit integrity duration under fire impact than the through line; plural branch lines; and plural branch off devices, wherein the consumer devices are connected to the branch lines, the branch lines are connected to the branch off devices, and the branch off devices are connected to the through line; wherein at least one of the branch lines has a lower circuit integrity duration under fire impact than the through line, and wherein the branch off devices comprise a thermally triggering disconnect device for providing circuit integrity of the through line under fire impact, wherein the disconnect device is configured to disconnect an electrical connection between the branch line and the through line self-acting when an ambient temperature increases to a predetermined value that is typical for a fire for securing the through line against a short circuit that occurs in a branch line under the impact of fire by automatically disconnecting the branch line from the through line.
