The circuit breaker product is primarily a primary-secondary fusion integrated post-mounted circuit breaker. It consists of a 10kV post-mounted circuit breaker, distribution network feeder terminal (FTU), voltage transformer, and connecting cables. It is mainly used for interrupting and closing load current, overload current, and short-circuit current in power systems. It supports frequent operation and is widely applied in the construction and renovation of power equipment in urban and rural power grids, industrial and mining enterprises, railways, etc., serving as protection and control in the power system.

The transformer is placed outside the pole and can be optionally equipped with electromagnetic transformers, electronic sensors, or digital sensors to meet the differentiated needs of users in different regions.
