The so-called power socket box is also called industrial plug, which has better waterproof effect and can avoid short circuit caused by rain. CEE connector CEE standard industrial plug socket is an explosion-proof socket, and the temperature is limited below 32 degrees. NEMA wiring device must be as small as possible in order to realize frequent commutation, but also to realize braking during commutation and acceleration after commutation. Therefore, it is necessary to adopt rapid commutation device and smart braking device. IP54, i.e. dust prevention is level 5: dust intrusion cannot be completely prevented, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof grade is Grade 4: prevent splashing water from intruding and prevent splashing water from all directions from intruding. It can be used in many fields such as railway, electric power, automobile, etc., and has the best waterproof effect and better performance in design level. In order to seek better protection, we should grasp it better according to the actual situation, and only in this way can we win better service, so it is also very important to choose suppliers. The power socket box made of more suitable materials has more beautiful appearance, stronger overload protection capability and higher protection level, so it needs to be handled better according to the actual situation, grasped better according to the actual situation and attracted more attention, so how to produce materials is also very important. After all, it will be used in different situations, and it must be a better choice. Generally speaking, the power socket box is widely used in industry, and its excellent waterproof performance can be used in an open environment, so these better ensure the premise that the power facilities can be safer. After all, a high-quality socket will have better performance when used, and the reliability brought by it will also have better performance.
