    Motorsicherung   für Drehstrommotoren. 
 EMI1.1 
 Körper b eingelagert, welcher aussen ein Gewinde trägt, um die   Motorfiihrung in einen leitenden   Teil   einschrauben   zu können, der mit dem   Plättchen   c metallischen Kontakt bekommt und die Weiterleitung des Stromes besorgt. Der Strom fliesst dann im   ungestörten   Betriebe von der Zuleitung zur Schraube g, weiter über die Feder d, den Bolzen a und den Sicherungsdraht h zum Kontaktplättchen c und über den Schraubensockel zum Motor. 
 EMI1.2 
 der oberwähnten Verbindungen kurz geschlossen, so dass auch die nächste Sicherung durchbrennen muss.

   Diese Sicherung schliesst nun ihrerseits wieder den Kontakt (t, d, e, so dass die   zweite Pha en-   leitung mit der dritten kurzgeschlossen und auch die in die dritte   Phasculcitung eingeschaltete Sicherung   zum Durchschmelzen gebracht wird. Es werden also bei   Überlastung einer Phase selbsttätig alle   drei Phasen abgetrennt, so dass der Motor vor   Zerstörungen geschützt   bleibt. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

    Motor fuse for three-phase motors.
 EMI1.1
 Body b is embedded, which has a thread on the outside so that the motor guide can be screwed into a conductive part, which comes into metallic contact with the plate c and takes care of the transmission of the current. The current then flows in undisturbed operation from the supply line to the screw g, further via the spring d, the bolt a and the safety wire h to the contact plate c and via the screw base to the motor.
 EMI1.2
 the above-mentioned connections are short-circuited, so that the next fuse must also blow.

   This fuse for its part now closes the contact (t, d, e again, so that the second phase line is short-circuited with the third and also the fuse switched on in the third phase line is blown. So if one phase is overloaded, all three phases separated so that the motor remains protected from destruction.
