A, anti-leakage protector installation method is what
Installation method is shown below. But pay attention to the following points:
1. leakage protector disconnect "N" line can not be connected to the metal shell.
2. Pay attention to the inlet and outlet of the earth leakage protector.
3. The phase and N wires of the earth leakage protector output cannot be used separately from other connections.
4. After installation, turn off the earth leakage protector and press the test button (T) of the earth leakage protector to check whether the earth leakage protector works properly.
Two, anti-leakage protector what are the brands
1, Siemens
Siemens was founded in 1847, specializing in electrification, automation and digitalization, it provides transmission solutions, industrial automation and one of the world's largest energy- and resource-efficient suppliers of industrial automation and health care, imaging equipment and laboratory diagnostics, such as the shower bandwagon.
2, Chint
Zhejiang Chint Electric Co., Ltd. was founded in 1997, specializing in the development, production and sales of more than 100 series of low-voltage electrical products, including power distribution equipment, control equipment, terminal appliances, power appliances and power electronics, etc., and it is the first listed company focusing on low-voltage appliances.
3, Schneider
Began in 1920 in France, is a global energy efficiency management experts, is the leading brand in the field of power distribution equipment, for energy and infrastructure, building and residential markets to provide total solutions. It is a leader in energy and infrastructure, industrial process control, building automation and data centers and networks.
Three, what are the tips for purchasing anti-leakage protectors
1. The current market leakage protectors can be described as a mixture of products with different product quality. When we buy, we must pay attention to whether the product has passed the national standard GB6829-86 "leakage current action protector".
2.The rated voltage of earth leakage protector is only 220v and 380v.Home electricity is single-phase electricity,so the voltage is 220v/50Hz.There are 3 levels of earth leakage protector,2,3 and 4,and the general family can choose 2 levels.
3, the mainstream leakage protector rated current specifications, but the overcurrent release rated current is only 10A, 16A, 20A three kinds of, in the purchase should be noted that the AC power for 220V operating voltage, the user can be in accordance with the 1kw current load 5A rough calculation of leakage protector rated current. Usually, the rated current value of the overcurrent detector can be determined according to the rated current value of 0.85 to 0.9 times.
4. Rated leakage current is the leakage current value that allows the leakage protector is not allowed to work. It is divided into three levels, household leakage protector need to choose high sensitivity to ensure the safety of body and property.
Four, anti-leakage protector how to install
The type of protection and installation of anti-leakage protector should be compatible with the environmental conditions and conditions of use, Class I mobile electrical equipment, with a metal casing and hand-held power tools, installed in the wet or strongly corrosive and other poor places of the electrical equipment, electrical construction machinery and equipment at the construction site, the temporary electrical equipment, the sockets in the hotel room, civil sockets in buildings with a high risk of electric shock, underwater lighting equipment in swimming pools or baths, power cords and electrical equipment installed in the water, and electrical medical equipment in hospitals that come into direct contact with the human body (except for thoracic operating rooms) should be installed with earth leakage protection devices.
The above is a small introduction to you about the full content of the leakage protector, I hope you read carefully, I hope the above can help you,.
