AUTOMATIC MINIATURE CIRCUIT BREAKER WITH Z-AXIS ASSEMBLABLE CONTACT ASSEMBLY

摘要

2111961 9322784 PCTABS00028 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.
