Places without fire, explosion danger, serious dirt, chemical corrosion and severe vibration.

Three-level common box type, simple structure, compact layout; power output is rotary type, with good sealing effect. The small moving mass in the body reduces the operating work and improves the mechanical life. The application of rotating arc technology improves the arc extinguishing efficiency and electrical life. The independence of the body structure can derive products with different performance and installation methods. Compared with vacuum and oil circuit breakers, it has significant advantages in structure, weight, safety, electrical strength, electrical life, maintenance and cost. Special arrangements and configurations of protection and measurement transformers with different ratios can be made according to user needs.
