Der Neuerung liegt daher die Aufgabe zugrunde, eine
Vorrichtung zur Einstellung der Auslöseparameter bei thermischen Überstromauslösern zu schaffen, mittels der eine einfache und vor unsachgemäßer Handhabung sichere Vorgabe der Auslöseströme erreicht wird, wobei eine deutliche und genaue Visualisierung des Auslösewertes gegeben ist.Scaling is difficult to read and relatively inaccurate.
The innovation is therefore based on the task of
To create a device for setting the tripping parameters for thermal overcurrent releases, by means of which a simple specification of the tripping currents is achieved which is safe from improper handling, while providing a clear and precise visualization of the tripping value.
Es zeigenThe advantageous properties of the innovation are described in more detail below using the embodiment shown in the drawing.

Fig. 2 eine perspektivische Darstellung des Einstellelementes, daß nach der Neuerung als würfelförmiger Körper ausgebildet ist.Fig. 1 the trigger mechanism of a thermobimetallic relay for monitoring the current-carrying conductors of a three-phase control line U, V, W for a consumer to be protected against overcurrent and
Fig. 2 is a perspective view of the adjustment element, which according to the innovation is designed as a cube-shaped body.
Die perspektivische Darstellung des Einstellelementes 1 in Fig. 2 verdeutlicht die Ausnehmungen 4', 4··, 4''', die auf den in dieser Darstellung sichtbaren Seiten des Einstellelementes 1 angeordnet sind. In dieser beispielhaften Ausführung ist auf jeder Seite eine Ausnehmung angeordnet. Eine Variante zu dieser Ausführung ist die Anordnung mehrerer Ausnehmungen auf einer Seite des Einstellelementes 1. Dadurch würde sich die Zahl der Einstellmöglichkeiten um ein Vielfaches erhöhen lassen. Die Einstellwerte sind deutlioch auf den Seiten aufgedruckt oder geprägt. Dabei ist der der Steckseite zugehörige Auslösewert immer auf der Sichtseite, vorzugsweise auf der Frontseite des Thermobimetall-Relais plaziert.on the other hand, it is determined by the path to be covered by the trigger pin 3. According to the invention, this path is determined by the setting element 1. The locking of the setting element is not shown in Fig. 1, since such a device is part of the general state of the art. The trigger pin 3 engages in the recess 4 of the setting element 1 and acts on the compensation bimetal 10 depending on the depth of the recess 4, whereby the rocker switch 9 experiences a corresponding path preload. To set a different trigger current, the setting element only has to be removed from the plug device 2 and turned to the desired trigger value. As a safety measure, it can be provided that when the setting element 1 is not plugged in, the trigger pin 3 acts on the compensation bimetal 10 to such an extent that a limit current cannot be exceeded.
The perspective view of the setting element 1 in Fig. 2 shows the recesses 4', 4··, 4''', which are arranged on the sides of the setting element 1 that are visible in this view. In this exemplary embodiment, there is a recess on each side. A variant of this embodiment is the arrangement of several recesses on one side of the setting element 1. This would increase the number of setting options many times over. The setting values are clearly printed or embossed on the sides. The trigger value associated with the plug-in side is always placed on the visible side, preferably on the front of the bimetallic relay.
