Cyclic opening/closure linear movement circuit breaker spring control mechanism having handle end/shaft activating inertial mechanism closure cam and closure bolt holding spring closed.
Cyclic opening/closure linear movement circuit breaker spring control mechanism having handle end/shaft activating inertial mechanism closure cam and closure bolt holding spring closed.
The spring control circuit breaker mechanism has a control spoke with a closure spring (10) and an opening spring (11). The spring closure acts on the handle end (25) near a shaft (27) which activates an inertial mechanism (26) with a closure cam (28). A closure bolt holds the spring closed, and the lock opening freeing it, and causing cam rotation. There is a rearmament motor (29) coupled by a free wheel (32). A bolt switch (33) controls movement of the control spoke.
