Ground fault current interrupter/arc fault current interrupter circuit breaker with fail safe mechanism

A circuit breaker comprising:

• a pair of separable contacts forming a first pole;
• an operating mechanism for operating said electrical contacts;
• electronic trip circuit responsive to currents flowing through said first pole for operating said operating mechanism in response to predetermined current conditions to open said separable contacts;
• means for operating said operating mechanism in response to a failure in said electronic trip circuit;
• wherein said means for operating said operating mechanism in response to a failure in said electronic trip circuit comprises:
• a solenoid electrically connected to said electronic trip circuit, said solenoid being energized in response to said failure in said electronic trip circuit;
• a plunger in said solenoid;
• a linkage assembly for operating said operating mechanism in response to movement of said plunger;
• wherein said linkage assembly comprises:
• an operating arm pivotally mounted adjacent to said solenoid such that movement of said plunger causes said operating arm to pivot about a pivot point;
• and
• a cable connecting said operating arm to said operating mechanism for operating said electrical contacts, whereby movement of said operating arm causes said operating mechanism to open said contacts.
