CW3V series intelligent vacuum universal circuit breakerDetailed product description：

The CW3V vacuum circuit breaker inherits the advantages of comprehensive protection functions, multiple measurement parameters, and rich maintenance functions of the CW3 circuit breaker. However, it has higher electrical and mechanical life, more rated short-circuit breaking times, stronger arc extinguishing ability, and can achieve true zero arcing. It is particularly suitable for places with relatively harsh environments and AC690V, 1140V power TN, TT, IT systems. Circuit breakers can not only protect power lines, but also protect equipment such as motors (circuit breakers meet the requirements of GB50055 for motor protection) and generators (circuit breakers meet the requirements of GB755 for generator protection), providing users with safer, more reliable, and more comprehensive low-voltage distribution protection solutions.
