exerts force acting on the back of the base. Residual current circuit breakers • of this type are known ·

According to the innovation, a bearing plate carrying the switching mechanism is used on such a residual current circuit breaker, which is fastened with a foot in a further chamber of the insulating base and forms a bearing for one end of the switching shaft actuated near the bearing plate by the switching mechanism, the the other end of the switching shaft finds a bearing in a Pfε ne of the Iaoliersockele. The innovation simplifies the mounting of the switching mechanism and the storage of the switching wall. While a special bearing plate was previously used on the known fault current circuit breakers to hold the switching mechanism and the switching shaft was laid in two additional bearing plates, the fault current circuit breaker under control requires a single component. Durui the power of switching * achanismus in the switch is the safe storage of the end not held by the support board of Schaitweile is practicing FfasB © of Isoiisrsocksls guaranteed *

Another advantageous one Training consists of darts that sit on the insulating base connected storage board an additional board is attached, the old of the bearing plate stores the switching mechanism and holds the holding magnet on the outside. This is the holding magnet alt dea a unified whole forming component from bearing plate, switch mechanism and switch shaft combined. Particularly ea is advantageous if the holding magnet is one by one The cover bit has a closed housing with the aid of a spring clip, which engages with a centering cam in the additional board and is attached to this by a screw. The encapsulation of the holding magnet protects it against the ingress of foreign bodies. At the same time, the CJe haus is particularly easy to attach as the Susatsplatise received-

The chambers 6 of the insulating base are covered by a sap 21 made of insulating material, which has partition walls 22 (Pig. 3). These partition walls 22 enclose with the partition walls 23 of the chambers the switching shaft 3 »so that a seal between || the chambers against arcing is given (Pig. 3 and The cap 21 can be held on the insulating base by grooved nails , whereby the switch cap 2 can also be drawn in to hold it. In the latter case, the switch cap has flips which act on the cap 21.
