Abstract
An electric circuit breaker including a spring energy store drive having a spring and a manual winding device for manually tensioning the spring. In accordance with an embodiment, the manual winding device includes a rotatable latching disk, a latching pawl arranged next to the disk, and a manual actuating device connected to the latching pawl. The latching pawl is guidable into a latching toothed portion of the disk. The pawl is also capable of moving, owing to an actuation of the actuating device. As a result, the disk is capable of rotating along a preset desired rotation direction for tensioning the spring. The latching toothed portion is asymmetrical and a force transmission from the pawl onto the disk is possible along the desired rotation direction. The disk slides along the pawl when the disk rotates along the desired rotation direction more quickly than the pawl.
