Abstract
Ogranicznik mocy zawierający mechanizm otwierający (110), pierwszy styk ruchomy (101) drugi styk (102) tworzące zestyk otwierany i zamykany za pośrednictwem mechanizmu otwierającego (110) oraz element bimetaliczny (120) przystosowany do wyzwalania mechanizmu otwierającego (110) w razie wystąpienia natężenia prądu przeciążeniowego (Imax1) o wartości większej niż natężenie prądu nominalnego (In) wskutek temperaturowego odkształcenia elementu bimetalicznego (120) i obwód stanowiący pętlę prądową, w której indukuje się pole magnetyczne w przypadku wystąpienia prądów zwarciowych cechuje się tym, że element bimetaliczny stanowi część obwodu pętli prądowej, zaś ta pętla prądowa jest skonfigurowana tak, że prąd zwarciowy (Imax2) generuje w niej siły elektrodynamiczne, które powodują przemieszczenie nieutwierdzonego końca elementu bimetalicznego (120) do momentu wyzwolenia mechanizmu otwierającego (110).
