Abstract

Die Erfindung betrifft ein elektrisches Installationsschaltgerät (1), mit einem Strompfad, der in einem Gehäuse (12) zwischen einer ersten und einer zweiten Anschlussklemme (13, 14) verläuft, und der an wenigstens einer ein feststehendes (2) und ein bewegliches Kontaktstück (3) umfassenden Kontaktstelle (4) geöffnet und geschlossen werden kann, mit einem von dem Strom des Strompfades wenigstens teilweise durchflossenen Kontakthebel (5), der mit dem wenigstens einen beweglichen Kontaktstück (4) versehen ist, mit einem Überstromauslöser (7), der ein Schaltwerkbetätigungsglied (48) umfasst, das bei einer Überstromauslösung von einer Ruhestellung in eine Auslösestellung übergeht, und mit einem Schaltwerk (8), das einen zwischen einer Ruhelage und einer Auslösungslage verschwenkbaren Hebel (21) umfasst. Das Schaltwerkbetätigungsglied (48) des Überstromauslösers ist mit einem Überstrom-Magnetkreis gekoppelt, so dass die auf das Schaltwerkbetätigungsglied (48) wirkende Kraft durch das Magnetfeld des Überstromes hervorgerufen ist, wobei der Magnetkreis einen als zylinderförmigen Rotor ausgebildeten Permanentmagneten umfasst, wobei der Magnetkreis weiter einen rohrförmigen Stator umfasst, der Teil des Magnetkerns des Magnetkreises ist, und der zumindest teilweise von zumindest einer Windung eines den Strom führenden Leiters umgeben ist, wobei der Rotor drehbar im Innenbereich des rohrförmigen Stators gelagert ist, und wobei an dem Rotor als weitere Anbauteile ausgebildet sind: eine in der Mittelachse verlaufende Bohrung zur Aufnahme einer als Schaltwerkbetätigungsglied wirkenden Welle, an jeder Stirnseite eine Lagerplatte, eine Fesselfeder zur Einstellung der Überstrom-Auslöseschwelle, ein Kupferrohr, das als elektromagnetisches Dämpfungselement zur Einstellung der Auslöseverzögerungszeit wirkt, so dass der Rotor mit den Anbauteilen als vorfertigbare Baugruppe in den Innenraum des Stators einsetzbar ist.

The invention relates to an electrical service switching device (1) having a current path which runs in a housing (12) between a first and a second connection terminal (13, 14) and which has at least one of a fixed (2) and a movable contact piece (2). 3) comprehensive contact point (4) can be opened and closed, with one of the current of the current path at least partially through contact lever (5) which is provided with the at least one movable contact piece (4), with an overcurrent release (7), the one Derailleur actuator (48), which merges in an overcurrent release from a rest position to a release position, and with a derailleur (8) comprising a pivotable between a rest position and a release position lever (21). The derailleur actuator (48) of the overcurrent release is coupled to an overcurrent magnetic circuit so that the force acting on the derailleur actuator (48) is caused by the magnetic field of the overcurrent, the magnetic circuit comprising a permanent magnet formed as a cylindrical rotor, the magnetic circuit further comprising comprises tubular stator which is part of the magnetic core of the magnetic circuit, and which is at least partially surrounded by at least one turn of a current-carrying conductor, wherein the rotor is rotatably mounted in the inner region of the tubular stator, and being formed on the rotor as further attachments a bore extending in the central axis for receiving a shaft acting as a rear derailleur actuator, at each end face a bearing plate, a restraining spring for setting the overcurrent release threshold, a copper tube serving as an electromagnetic damping element for setting the tripping V delay time acts, so that the rotor can be used with the attachments as prefabricated assembly in the interior of the stator.
