FIELD: electricity.
SUBSTANCE: power circuit breaker drive system has swing actuating arm (17) interacting with locking component (14) that has the first locking area (27) and the first unlocking area (28) moved into the area of swing actuating arm (17). Locking component (14) has the second area of unlocking (30) and the second area of locking (31), which interact with swing arm (13) of another switching device. Actuating (17) and swing (13) arms are installed so that they can be rotated round the respective rotary axes oriented in parallel towards each other.
EFFECT: development of the drive system wherein locking is implemented by durable structure, which demands less costs.
