Abstract

Es wird eine Vorrichtung zur Verhinderung einer Betätigung eines Betätigungsdruckknopfes (11) für ein elektrisches Installationsgerät (10), insbesondere für einen elektrischen Leitungsschutzschalter oder Fehlerstromschutzschalter beschrieben, bei dem die Vorrichtung einen U-förmigen Bügel (16) aus federndem Material aufweist, dessen Schenkelenden (19, 20) nach innen abgebogen und in sich diametral gegenüberliegende Löcher (13, 15; 13a, 15a) des Betätigungsdruckknopfes (11) einfügbar sind. Die Schenkel (17, 18) des U-förmigen Bügels (16) sind von einem auf diesem verschiebbaren Halter (21) umfaßt und in einer ersten Stellung, in der der Halter (21) sich im Bereich des Steges (22) des Schenkels befindet, aufbiegbar, so daß die Schenkelenden (19, 20) in die Löcher einsteckbar bzw. herausnehmbar sind. In einer zweiten Stellung, in der der Halter zu den Schenkelenden (19, 20) hin verschoben ist, sind sie festgehalten, wobei zwischen dem Halter (21) und dem Steg (22) des Bügels ein Zwischenraum (24) freigelassen ist, durch den der Schloßbügel eines Vorhängeschlosses hindurchsteckbar ist.

Figure 00000001
A device for preventing actuation of an actuation pushbutton (11) for an electrical installation device (10), in particular for an electrical circuit breaker or residual current circuit breaker, is described, in which the device has a U-shaped bracket (16) made of resilient material, the leg ends ( 19, 20) are bent inwards and diametrically opposed holes (13, 15; 13a, 15a) of the actuating pushbutton (11) can be inserted. The legs (17, 18) of the U-shaped bracket (16) are encompassed by a holder (21) which is displaceable thereon and in a first position in which the holder (21) is located in the region of the web (22) of the leg , bendable so that the leg ends (19, 20) can be inserted or removed in the holes. In a second position, in which the holder is displaced towards the leg ends (19, 20), they are held in place, an intermediate space (24) being left between the holder (21) and the web (22) of the bracket, through which the padlock of a padlock can be pushed through.
