Abstract
A mechanism for a circuit breaker contact arm that allows current limiting by reducing the opening time is disclosed. A contact arm is coupled to a contact arm mechanism that includes a carrier coupled to a first pair of linkages. A second pair of linkages is coupled to the first pair of linkages. A second carrier coupled to the second pair of linkages attaches to the contact arm mechanism to a main circuit breaker mechanism through a lay shaft assembly. Upon the occurrence of an undesired electrical condition, the contact arm mechanism moves from a locked to an open position allowing the contact arm to blow open.
