Design
The circuit-breaker is a switching apparatus with three poles mounted on the frame. The circuit-breaker is controlled by electromagnetic drive.
Inside the frame there are mounted the following parts:
- two opening springs
- two oil buffers
- a shaft of circuit-breaker
The shaft houses two mechanical indicators of the circuit-breaker position. On the frame there are insulating partitions ensuring the required electrical strength among poles. Current-conducting buses are connected to current collectors.
