Description
AB-3S-12 series circuit breaker is the company's comprehensive domestic and foreign advanced technology, embodies the "intelligent, energy saving, environmental protection, dimension-free" design concept, combined with the actual situation of China's power distribution network and the smart power grid construction requirements, the latest development of a new generation of intelligent vacuum circuit breaker with independent intellectual property rights. The product can be used as the switch of 10kV side and 10kV outgoing line of the main transformer substation, or the switch on the pillar of t he distribution network. This product integrates the functions of measurement, control, protection, communication, fault isolation, network reconstruction and so on. With high automation and intelligence, it is the preferred equipment to realize the automation of distribution network and miniaturization of substation.
