摘要： An improved miniature circuit breaker (10) 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 magnetic-yoke (12) and armature (17) which comprise the current response mechanism (6) for the circuit breaker (10) are designed to interact with each other so that the magnetic armature (17) can easily be Z-axis assembled onto the magnetic yoke (12).
