Abstract

The device has a first current path containing a main bimetallic element (10) and a connected compensation bimetallic element (13) coupled together with a coupling sliding element (21) and a secondary current path containing a selective bimetallic element (26), whereby the bimetallic elements are arranged in parallel. The selective bimetallic element acts on one interlocking point of a switch lock (19) with an associated transfer element (31).
