Low-voltage Pole-mounted Circuit Breakers Are Generally Installed At Main Line Branches And Larger Branch Lines.

In overhead power distribution networks, Lv Pole Mounted Circuit Breakers is mainly deployed at the connection points between main lines and large branch lines. Power system design specifications stipulate that when a branch line serves an important user or a large load, a circuit breaker should be installed at this location as a branch switch.

This arrangement ensures that each large branch line originating from the main line has its own independent breaking and protection device. Once activated, the circuit breaker can isolate the branch line from the main line.

Furthermore, because the circuit breaker body is designed for air arc interruption or vacuum arc extinguishing, it can quickly disconnect in the event of a short circuit or overload. The disconnection point is located at the branch point between the main line and the branch line.
