<p>A circuit breaker has a spring-loaded switching mechanism. The spring force for the connecting and disconnecting process can be adjusted separately without affecting each other. The switching spring stressed by the drive is in working contact with the release mechanism. It is stressed during the switching process. There is an engaging bracket (4) between two pressure springs (6, 7) which follows the switching movement. In one direction it can be located onto a roller (21) which can be shifted at right angles to the direction of the spring. The roller is shifted against the action of a U-shaped leaf spring. The movement of the roller is controlled by a slider controlled by the drive.</p> |
