Abstract

A circuit interrupter comprises a pair of fixed 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 movable contact strips has a fixed end and a movable end which has a movable contact arranged for contacting one of the corresponding fixed contacts. The movable component is disposed to sustain the movable ends of the movable contact strips and is capable of either being latched with or released from the reset component to move between a first position where the movable contacts are separated from the fixed contacts and the movable contact strips are separated from the reset contact, a second position where either the movable contact strip contacts the reset contact and the movable contacts are separated from the fixed contacts, and a third position where the movable contacts make contact with the respective fixed contacts and the movable contact strips are separated from 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.
