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 trip mechanism including the trip lever, and the associated activation means, tension means and reset means are defined by elements designed to interact in a Z-axis assemblable fashion. The trip mechanism components are also designed for improved trip action and enhanced breaker performance in repeated OPEN, CLOSED, and TRIP operations.
