Abstract
Description
technical field
[0001] The invention relates to a pluggable surge arrester according to the preamble of claim 1, comprising one or more overvoltage protection elements and a thermal overcurrent protection device, said overvoltage protection elements being arranged In the structural unit with an optical fault display, the overcurrent protection device includes a mechanical actuating device for triggering a communication contact for fault signaling.
[0002] Furthermore, the invention comprises a basic component for mechanically and electrically receiving at least one pluggable surge arrester. Background technique
[0003] Starting from the German utility model DE 20 2004 006 227, a surge arrester with communication contacts for fault signaling is known. Potential-free mechanical triggering is achieved in the prior art by means of installed varistors of the grid spark gaps used in the corresponding plug-in parts or by thermal monitoring of the triggering unit via pretensioned...
