Electric circuit protective device with energy diverting means

Claim 1

AN ELECTRIC CIRCUIT PROTECTIVE DEVICE COMPRISING: (A) AT LEAST ONE PAIR OF RELATIVELY SEPARABLE CONTACTS; (B) A MAGNETIC COR MEMBER; (C) A MAGNETIC ARMATURE MEMBER MOVABLE TOWARD SAID AWAY FROM SAID CORE MEMBER; (D) MEANS BIASING SAID ARMATURE MEMBER FOR MOVEMENT AWAY FROM SAID CORE MEMBER; (E) MEANS FOR CAUSING OPENING MOVEMENT OF SAID SEPERABLE CONTACTS UPON MOVEMENT OF SAID MAGNETIC ARMATURE AWAY FROM SAID CORE; (F) A MAIN WINDING ON SAID CORE MEMBER CONNECTED ELECTRICALLY IN SERIES WITH SAID SEPARABLE CONTACTS; (G) SAID MAGNETIC ARMATURE BEING ADAPTED TO BE HELD IN ATTRACTED POSITION WITH RESPECT TO SAID CORE MEMBER BY MAGNETIC FLUX CREATED BY FLOW OF A FIRST PREDETERMINED CURRENT THROUGH SAID MAIN WINDING; (H) A SECONDARY WINDING CARRIED BY SAID CORE MEMBER; (I) A CURRENT LIMITING DEVICE CONNECTED ELECTRICALLY IN SERIES WITH SAID SEPARABLE CONTACTS AND SAID MAIN WINDING, SAID CURRENT LIMITING DEVICE HAVING A RELATIVELY LOW ELECTRICAL RESISTANCE UNDER NORMAL OPERATING CONDITIONS AND CHANGING TO RELATIVELY HIGH RESISTANCE UPON THE OCCURRENCE OF PREDETERMINED CURRENT CONDITIONS THERETHROUGH WITHOUT PERMANENTLY INTERRUPTING CURRENT THERETHROUGH; (J) SAID SECONDARY WINDING BEING CONNECTED ELECTRICALLY IN PARALLEL WITH SAID CURRENT LIMITING DEVICE, WHEREBY THE CHANGE OF RESISTANCE AND SAID CURRENT LIMITING DEVICE FROM SAID RELATIVELY LOW ELECTRICAL RESISTANCE TO SAID RELATIVELY HIGH ELECTRICAL RESISTANCE CONDITION CAUSES AN INCREASED FLOW OF CURRENT THROUGH SAID SECONDARY WINDING; (K) SAID SECONDARY WINDING WHEN ENERGIZED CREATING FLUX ACTING TO DECREASE THE HOLDING EFFECT OF FLUX FROM SAID MAIN WINDING, RELEASE OF SAID MAGNETIC ARMATURE MEMBER, AND OPENING OF SAID CONTACTS.
