Abstract
A circuit breaker comprising a case and a stationary contact mounted within said case. A movable contact is movable into and out of engagement with the stationary contact. An operator is pivotally mounted within said case and a collapsible linkage interconnects the said operator and the movable contact. An electromagnetic sensing device collapses the collapsible linkage upon predetermined electrical overloads to move the contacts from the contacts 'closed' position to the contacts 'open' position. The collapsible linkage carries a restraining means for restraining the operator in a position intermediate the 'open' and 'closed' positions of the contacts.
