Title
(DE) SCHUTZSCHALTER
(EN) PROTECTION SWITCH
(FR) DISJONCTEUR DE PROTECTION
Abstract
(DE)
Es wird ein in Hinblick auf ein schnelles Schaltverhalten besonders geeigneter Schutzschalter (1) angegeben. Der Schutzschalter (1) umfasst mindestens ein einpoliges Schutzschaltermodul (2). Das Schutzschaltermodul (2) umfasst ein Gehäuse (3), ein einen Bewegkontakt (84) tragenden Schaltarm (43), der zwischen einer Schließstellung und einer Öffnungsstellung gegen einen Festkontakt (85) schwenkbeweglich ist, eine Handbestätigungsmechanik (42) zur manuellen Verstellung des Schaltarms (43) zwischen der Schließstellung und der Öffnungsstellung sowie eine Auslösemechanik (44) zur automatischen Rückstellung des Schaltarms (43) in die Öffnungsstellung bei Eintritt einer Auslösebedingung. Der Schaltarm (43) ist in Richtung der Öffnungsstellung federbelastet und umfasst einen mit der Handbetätigungsmechanik (42) verklinkbaren Klinkenhebel (49) sowie einen den Bewegkontakt (84) tragenden Kontakthebel (48), wobei der Klinkenhebel (49) schwenkbeweglich am Gehäuse (3) gelagert ist und mit dem Kontakthebel (48) über ein Drehgelenk (81) verbunden ist. Die Auslösemechanik (44) weist einen Auslöseschieber (53) auf, der durch einen Auslöser (55, 56) aus einer Bereitschaftsstellung in Richtung auf eine Auslösestellung verschiebbar ist, und der den Schaltarm (43) dabei derart beaufschlagt, dass der Kontakthebel (48) drehfixiert ist.
(EN)
A protection switch (1) is disclosed, which is particularly suitable where fast switching methods are concerned. The protection switch (1) comprises at least one single-pole protection switch module (2). The protection switch module (2) comprises a housing (3), a movable contact (84) mounted on a switching arm (43), which can be pivoted against a fixed contact (85) between a closed position and an open position, a manual activation mechanism (42) for manually setting the switching arm (43) between the closed position and the open position, and a release mechanism (44) for automatically resetting the switching arm (43) into the open position when a release condition occurs. The switching arm (43) is spring-loaded in the direction of the open position and comprises a latching lever (49) that can be latched with the manual activation mechanism (42), and a contact lever (48) bearing the moveable contact (84), wherein the latching lever (49) is pivotably mounted on the housing (3) and joined to the contact lever (48) via a swivel joint (81). The release mechanism (44) comprises a release slider (53), which can be displaced by means of an actuator (55, 56) from a ready position towards a release position, and which thereby impinges on the switching arm (43) in such a way that the contact lever (48) is torsionally fixed.
(FR)
L'invention concerne un disjoncteur de protection (1) particulièrement adapté à une commutation rapide. Le disjoncteur de protection (1) comprend au moins un bloc de disjoncteur unipolaire (2). Le bloc de disjoncteur unipolaire (2) comprend un boîtier (3), un bras de commutation (43) qui porte un contact mobile (84) et peut basculer entre une position de fermeture et une position d'ouverture contre un contact fixe (85), un mécanisme de commande manuelle (42) servant à déplacer manuellement le bras de commutation (43) entre la position de fermeture et la position d'ouverture, ainsi qu'un mécanisme déclencheur (44) pour ramener automatiquement le bras de commutation (43) en position d'ouverture lorsqu'une condition de déclenchement survient. Le bras de commutation (43) est sollicité par un ressort en direction de la position d'ouverture et il comprend un levier à cliquet (49), encliquetable avec le mécanisme de commande manuelle (42), ainsi qu'un levier de contact (48) portant un contact mobile (84). Le levier à cliquet (49) est monté pivotant sur le boîtier (3) et il est relié au levier de contact (48) par le biais d'une articulation à charnière (81). Le mécanisme de déclenchement (44) présente une glissière de déclenchement (53) qui peut être déplacée par un déclencheur (55, 56) depuis une position d'attente en direction d'une position de déclenchement et qui agit sur le bras de commutation (43) de telle façon que le levier de contact (48) soit immobilisé en rotation.
