摘要： An improved miniature circuit breaker (1, 2) 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 (6) including the trip lever (31), and the associated activation means (75), tension means (43) and reset means (35) are defined by elements designed to interact in a Z-axis assemblable fashion. The trip mechanism components (6) are also designed for improved trip action and enhanced breaker performance in repeated CLOSED, and TRIP operations.

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).

摘要： A miniature circuit breaker is provided which is adapted to improve automatic assembly of all components. 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 (45, 46) to make or break the electric circuit is formed of elements designed to interact in a Z-axis assemblable fashion. The movable contact (45) is defined on a contact carrier or blade assembly (41) which is adapted for Z-axis assembly and also provides increased arc erosion resistance and improved opening of the breaker contacts.
