摘要： The invention relates to an installation switchgear, particularly a selective protective switch, having a housing comprising a mounting side, a front and rear face, and wide as well as front and rear narrow sides connecting the mounting side and the face, having a main current path extending between an input terminal and an output terminal, the main current path comprising a main contact point equipped with an arc quenching chamber, a striker armature system bringing the main contact point into the open position, and a main thermal bimetal, which acts on a switching mechanism having a locking position such that the contact point remains permanently open, having a secondary current path in which a current limiting resistor, a selective thermal bimetal also acting on the switching mechanism, and a separating contact point to be opened by the switching mechanism are disposed, and having a handle, by means of which the main contact point can be opened and closed via the switching mechanism, characterized in that a) the secondary current path is switched in parallel to the series connection of the first bimetal via the main contact point, b) the main contact point is configured as a single contact point having a fixed and a movable contact piece, and c) a phase terminal bar extending close to the mounting side and approximately parallel to the same is provided in the housing interior and connected to the input terminal, on the free end of which a clamping contact protruding from the housing on the mounting side is attached in an installation splitter for clamping to bus bars.

摘要： The invention relates to an installation switching device, in particular a selective circuit breaker, comprising: a housing, which comprises a fastening side, a forward front side and a rear front side, and broad sides and forward and rear narrow sides which connect the fastening side and the front side; a main current path running between an input terminal and an output terminal, said main current path containing a main contact point that is provided with an arc-quenching chamber, a striker armature system, which brings the main contact point into the open position, and a main thermostatic bimetal piece, which acts on a latching mechanism having an interlocking point, such that the contact point remains permanently open; a secondary current path, in which a current-limiting resistor and a selective thermostatic bimetal piece, which likewise acts on the latching mechanism, as well as an isolating contact point that can be opened by the latching mechanism are arranged; and a handle, by means of which the main contact point can be opened and closed via the latching mechanism. The secondary current path is connected in parallel to the series connection comprising the first bimetal piece and the main contact point, and the main contact point is designed as a single contact point having a fixed and a moving contact piece. At least one first vent opening for discharging waste gases from the arc-quenching device is disposed on a narrow side next to the connecting terminal. A recess for fastening the installation switching device to a DIN mounting rail is designed on the fastening side, a second vent opening for discharging waste gases from the arc-quenching device is disposed in the fastening side, and a quick fastening device having a slide, which carries a movable projection and encloses the housing at the broad sides and which can be acted on by means of a spring toward the inner space of the recess, is disposed on the fastening side.
