With the development of mechanical and electrical industry, electricity systems are becoming increasingly complex

With the development of mechanical and electrical industry, electrical systems become more complex, the traditional contactor or starter demanding. In order to meet the electricity  air circuit breaker , intelligent demand, electrical factory in developed countries with a wide use of computer technology to develop multi-functional. Intelligent, high-performance, high-reliability magnetic contactors and electromagnetic starter. Its main feature is mechatronics, computer technology will be introduced  mcb circuit breaker  control appliances, on the one hand to meet the requirements of the basic functions of traditional appliances, on the other hand the control of intelligent appliances, in particular, can increase the variety of functions, such as protection monitoring communication function, can be used for the separation of electricity network system components.
