Abstract:
1. An installation switching device comprising: a housing having an attachment face, a front front face, a rear front face, a first broad face, a second broad face, a front narrow face, and a rear narrow face, wherein the front and the rear narrow faces connect the attachment face and the front and rear front face; a main contact point having an arc quenching chamber; an input terminal; an output terminal, wherein a main current path runs from the input terminal through the main contact point to the output terminal; an impact-style armature system configured to move the main contact point to an open position, wherein the main contact point is in a form of a single contact point formed having a fixed and a moving contact piece; a latching mechanism having a latching point and configured to open an isolating contact point disposed in a secondary current path parallel to the main current path; a main thermostatic bimetallic strip configured to act on the latching point to as to cause the main contact point to remain in the open position; a current limiting resistor disposed in the secondary current path; a selective thermostatic bimetallic strip disposed in the secondary current path and configured to act on the latching mechanism; a handle configured to act on the latching mechanism so as to open and close the main contact point; and a phase connecting rail disposed in an interior of the housing and close to and parallel to the attachment face and connectable to the input terminal, wherein a terminal contact is fitted at a free end of the phase connecting rail and projects out of the housing on the attachment face, the terminal contact configured to clamp on a busbar in an installation distribution block.
