Low-voltage electrical appliances refer to electrical appliances with rated voltage levels of 1200V AC and 1500V DC. The most commonly used three-phase AC voltage level in China's industrial control circuit is 380V. Only in certain industry environments, other voltage levels are used, such as 127V for electric drills in underground mines, 660V for transport machines, and 1140V for shearers. There are many brands of low-voltage electrical appliances imported from China. After years of development, Wal-Mart Electric (China) Co., Ltd. has become the research, development, production and sales of high, medium and low voltage electrical, control and protection devices, industrial electrical, communication, network and energy industries. The service is integrated into one. In recent years, the products are mainly sold in VORATSC series dual power automatic transfer switch, VORATSP series dual power automatic transfer switch, VORCPS series control and protection switch electrical, VORB series miniature circuit breaker, VORM series plastic case circuit breaker VORW21 series intelligent universal circuit breaker, digital display instrument series digital display display table, multi-function instrument series power meter. There are many types of low-voltage electrical appliances, various functions, various structures, wide applications, different working principles, and many different methods for classification of low-voltage electrical appliances. For example, according to different purposes: (1) distribution electrical appliances: mainly used in low-voltage distribution systems. It is required to operate accurately and reliably when the system fails, and has corresponding dynamic stability and thermal stability under the specified conditions, so that the electrical appliance will not be damaged. Commonly used power distribution appliances include knife switches, transfer switches, fuses, and circuit breakers. (2) Control electrical appliances: mainly used in electric drive systems. It requires long life, small size, light weight and fast, accurate and reliable action. Commonly used control appliances include contactors, relays, starters, main electrical appliances, electromagnets, and the like. Or according to the action mode: (1) automatic electrical appliances: rely on the changes of their own parameters or the role of external signals, automatically complete the action of switching on or off, such as contactors, relays and so on. (2) Manual electrical appliances: electrical appliances that are switched by manual operation, such as knife switches, transfer switches, buttons, and the like.
