Abstract: The invention relates to a transmission shaft for an installation switchgear comprising at least one contact point, a hammer armature system for opening the contact point in the event of a short-circuit and a switching lock with a release lever, wherein the hammer armature acts upon the switching lock in order to unlatch it, thereby opening permanently the contact point. The transmission shaft can be mounted into the installation switchgear so as to be pivotable between an idle position and a tripping position for ensuring the mechanical coupling of the hammer armature with the release lever and a short-circuit signaling unit and for ensuring the mechanical coupling of an auxiliary release with the release lever. The transmission shaft comprises a first, internally positioned partial shaft that is rotatably mounted in a second, externally positioned partial shaft in such a manner that the first partial shaft, independently from the second partial shaft, is pivotable between the idle position and the release position when the second partial shaft is in the idle position and that the second partial shaft entrains the first partial shaft into the release position during pivoting from its idle position to the release position.

Abstract: The invention relates to an installation switchgear (1) with at least one pole current path (2), said switchgear comprising two fixed contact pieces (5, 6) and two mobile contact pieces (8, 9) arranged on a mobile contact bridge (7), forming a pole switch with two contacts and a double break. The contact bridge (7) is acted upon by a pusher (12) in the opening direction (O) and by a contact pressure spring (11) in the closing direction. The two contacts are closed in the connected state, and in the event of a short circuit, the contact bridge is pushed in the opening direction thereof and the pusher is moved into its trigger position in which it acts on the contact bridge in order to open same. Said switchgear is also provided with an electromagnetic tripping device (13), the armature of which releases the latching position of a switch latch (15) in the event of a short-circuit, such that the switch latch maintains the pusher (12) in the trigger position thereof by means of an actuating lever (17) which lags in relation to the pusher (12) and moves from the idle position into the disconnected position thereof. The contact bridge (7) is thereby permanently held open against the force of the contact pressure spring (11). The installation switchgear (1) comprises a control slide (30) mounted in such a way that it can be displaced between a release position and a locking position and, in its locking position, maintains the pusher in the trigger position thereof. The movement of the actuating lever from its idle position into its disconnected position causes the control slide to move from its locking position into its release position such that the pusher (12) is released from the trigger position thereof.
