Product features：
· The shell material is high-temperature resistant and flame-retardant VO-grade nylon. The inlet and outlet terminals are treated with silver plating of copper to ensure excellent durability and weather resistance;
· It has a switch button for switching between maintenance and operation modes;
· In operation mode, it has an automatic closing function upon detecting pressure;
· In maintenance mode, the circuit breaker will not perform remote closing operation, which is suitable for line and equipment maintenance and repair;
· It adopts a quick-tripping mechanism, with quick and reliable tripping and opening;
· It is fixed with 35mm standard guide rails, facilitating quick installation, maintenance or replacement by customers;
· It has a high interrupting capacity, with rapid and reliable arc extinguishing and high interrupting capability;
· It has an integrated coaxial structure to achieve linkage of all poles, with good synchronization of opening and closing;
· The undervoltage and loss-of-voltage protection function is integrated with the operating mechanism;
· It has a 15mm wiring depth and large-torque wire clamping screws, ensuring a tight connection.
