ABSTRACT:
A circuit interrupter comprises a pair of fixed contact strips, a pair of load contact strips, a pair of movable contact strips, a reset component, a movable component, and a tripping component that contains a reset contact. Each of the fixed contact strips has a fixed contact. Each of the load contact strips has a load contact. Each of the movable contact strips has a fixed end and a movable end. Each movable end has a first movable contact arranged for contacting one of the corresponding load contacts and a second movable contact arranged for contacting one of the corresponding fixed contacts. The movable component disposed to sustain the movable ends of the movable contact strips, the movable component capable of either being latched with or released from the reset component to move between a first position where the first movable contacts are separated from the load contacts, and the second movable contacts are separated from the fixed contacts, and the movable contact strips are not electrically coupled to the reset contact, a second position where the first movable contacts are separated from the load contacts, and the second movable contacts are separated from the fixed contacts, and at least one of the movable contact strips is electrically coupled to the reset contact, and a third position where the first movable contacts make contact with the corresponding load contacts, and the second movable contacts make contact with the corresponding fixed contacts, and the movable contact strips are not electrically coupled to the reset contact. The tripping component is capable of latching the reset component with the movable component for the movable component to move to the third position upon detection of a reset request and releasing the reset component from the movable component for movable component to move to the first position upon detection of a fault condition.
