A load switch is possible with load off of a self-extinguishing function but no arc chute on the structure of its breaking capacity is very small and limited two isolation switch is generally not with load off there can be breaking the load isolation switch only structure and the load switch is relatively simpler three different load switch and isolating switch can form a clear majority of the circuit breaker off point does not have a small number of isolation breaker with isolation isolation switch 4 does not have the protection function is generally load switch plus fuse protection Protection only 5 quick break and overcurrent circuit breaker breaking capacity in the manufacturing process can be done mainly by increases in high current transformer with a secondary device may have short-circuit protection Overload protection leakage protection features such as load switch and isolation switch, you can form a clear break point Huzhou load switch, circuit breaker does not have most of Wuhan load isolation switch, there are a few breaker with isolation. Disconnectors do not have protection, load switch with overload protection function. Load switch and fuse combination of electrical automatic tripping of the circuit breaker with some of the features. The breaker may have short-circuit protection, overload protection, leakage protection and other functions. Hebi load switch, Huayi Electric Power (certified), load switch provided by Xian Huayi power plant. Xian Huayi power plant (www.xahy.com) is a leader in Xi'an, high voltage circuit breakers, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
