Abstract: An installation switching apparatus includes: a housing; at least one contact point; an exhaust air duct which in an upstream portion thereof receives arc gases of a switching arc that has been created at the at least one contact point, and by way of an exhaust air opening in a housing wall of the housing in a downstream portion of the exhaust air duct the exhaust air duct releases the arc gases into an environment of the housing; at least one thermal release; and a set screw for setting the at least one thermal release. The set screw at an activation end thereof has a formed element for contacting in a form-fitting manner a tool for rotating activation of the set screw. An operative end of the set screw is coupled to the at least one thermal release.

Abstract: An electrical service switching device includes: a housing in which at least one contact point is arranged, the housing having a first terminal connection area, in which a plug-in terminal is arranged and is configured for for the purpose of connecting the service switching device to a busbar, and a second terminal connection area, in which a screw terminal for the connection of connection conductors is arranged, the first and the second terminal connection area being formed on opposite narrow sides of the housing; and an arc quenching device associated with the at least one contact point and having an arc inlet side and an exhaust air side at which an exhaust air flow can exit. The exhaust air side of the arc quenching device is oriented towards the first terminal connection area in the housing interior.

Abstract: An installation switching device has a housing and screw connecting clamp with an essentially frame-shaped clamping part having longitudinal faces, narrow faces and broad faces, a head-clamp screw received in a clamping part threaded aperture, and a current rail arranged fixed in the device extending through the frame-shaped clamping part interior, wherein a current rail broad face is oriented, as assembled, parallel to a clamping part broad face facing the head clamping screw, the screw supporting itself, screwed in, on the current rail, wherein consequently, the clamping part is displaceable in its longitudinal direction, parallel to the narrow face, relative to the current rail by further screwing in the head clamping screw so a connecting conductor can be fixedly clamped between the current rail face remote from the screw and the clamping part broad face remote from the screw, the housing having a screw receiving region guiding the screw head.
