EMI2.1
PATENTANSPRUCH : Maximalausschalter, dessen Auslösen durch einen im Stromkreise liegenden Hitzdraht oder ein Band mit Nobonschiusswidorstand bewirkt wird, gekennzeichnet durch einen Noben- schlusswiderstand, der bei momentanen StroDlstösson1 welche die normale Stromstärke um wenigstens 500 übersteigen, sich langsamer erwärmt als der wirksame Leiter, zu dem Zwecke, den wirksamen Leiter gegen zu hohe Erwärmung be Stromstössen zu schützen und den Schalter trager zu machen.
EMI2.2
PATENT CLAIM: Maximum circuit breaker, the triggering of which is caused by a hot wire in the circuit or a band with a non-contact resistor, characterized by a shunt resistance which, with instantaneous current impulses which exceed the normal current strength by at least 500, heats up more slowly than the effective conductor to which Purposes to protect the effective conductor against excessive heating be current surges and to make the switch wearier.
