Abstract
An improved miniature circuit breaker is provided which is adapted to improved automatic assembly of all components thereof. Key components of the breaker are individually and collectively designed to be susceptible to total Z-axis assembly. In particular, the circuit breaker operating mechanism which operates the contacts thereof to make or break the electric circuit is formed of elements designed to interact in a Z-axis assemblable fashion. The movable contact is defined on a contact carrier or blade assembly which is adapted for Z-axis assembly and also provides increased arc erosion resistance and improved opening of the breaker contacts.
