Abstract
A circuit breaker that includes circuit breaker poles, an operating mechanism and a tripping system. Each circuit breaker pole includes a pole housing and a contact system that includes a moving contact mechanism and a static contact. The operating mechanism drives the moving contact mechanisms. The tripping system includes groups of tripping mechanisms and an adjusting mechanism. Each group of tripping mechanisms includes a conductive plate, a magnetic yoke and an armature. The conductive plate passes through the magnetic yoke. Each circuit breaker pole has a group of tripping mechanisms. Each contact system is electrically connected to a corresponding conductive plate. Each adjusting mechanism includes a linkage rod. Each group of the tripping mechanisms includes an insulated transmission rod having one end inserted into the pole housing and connected to the armature, and another end that protrudes out of the pole housing and trips the operating mechanism.
