1. Quick response ability: Due to the high rated current, when a system malfunction occurs, it can quickly cut off the power supply to avoid further expansion of the accident. This helps to reduce power outage time and impact on users.

2. High reliability: Due to the use of advanced electronic technology and design, this circuit breaker can withstand various surges and disturbances and maintain good operating conditions. This enables it to provide reliable protection and control even in high-pressure and harsh environments.

3. Multifunctionality: In addition to basic protection functions, it may also have other additional functions, such as remote monitoring and control, automatic reclosing, etc., which can improve the safety and manageability of the system.

4. Low maintenance cost: Due to its simple structure and easy operation, this circuit breaker and controller do not require frequent maintenance or replacement of components, thereby reducing maintenance costs.

5. Reliable electrical connection: Due to the high rated voltage, this type of circuit breaker can be connected to the system using standard terminal blocks or cables without the need for special connectors or wires. This simplifies the installation process and improves construction efficiency.
