? There are many brands of low-voltage circuit breakers, but there are many restrictions on low-voltage ones. A brand needs a lot of comprehensive strength, and we need to know a lot about the brand of low-voltage circuit breaker, not only the brand, but also the history, advantages, characteristic technology and so on. Low-voltage circuit breakers belong to physics, and those who have studied physics know this aspect better. We need to know more about the obscure terms in our life. If you want to know more, I will introduce them to you from the following aspects.
Low-voltage circuit breaker (once called automatic switch) is a kind of switching appliance that can not only connect and disconnect normal load current and overload current, but also connect and disconnect short-circuit current. The low-voltage circuit breaker not only plays a control role in the circuit, but also has certain protection functions, such as overload, short circuit, undervoltage and leakage protection. Low-voltage circuit breakers are classified in many ways, including selective (with adjustable parameters of protection device) and non-selective (with adjustable parameters of protection device), and air-type and vacuum-type according to arc extinguishing medium (at present, most of them are air-type). Low-voltage circuit breakers have a wide range of capacities, ranging from 4A to 5A. Low-voltage circuit breakers are widely used in feeder lines at all levels of low-voltage distribution system, power control of various mechanical equipment and control and protection of power terminals.
Top ten brands of low-voltage circuit breakers: Zhengtai, PEOPLE, Tianzheng, Lonon, Legrand, Dingta, Long March, Daquan, Changshu and Minyang. Common domestic brands: Shanghai People's Electric Appliances, Zhengtai, Delixi, Changshu, Tianzheng, Shenyang Wofu and Tianshui.
Shanghai People's Electric Appliance Zhengtai Delixi Changshu Tianzheng Shenyang Siwo
Famous electrical appliances brands (circuit breakers, molded cases, dual power supplies, frame switches, contactors, relays) include commonly used imported brands: Schneider ABB, Siemens Fuji Haig TCL, and Muller.
commonly used domestic brands: Shanghai People's Electric Appliance Chint Delixi Changshu Tianzheng Shenyang Siwo Tianshui. At present, the brands of low-voltage circuit breakers on the market are Schneider, ABB, Siemens, Liangxin Circuit Breaker, Fuji, TCL, mitsubishi electric, A-B, LG, Admiralty Muller, festo, GE, Changshu Switch, Shanghai Ergong, Hequan, Delixi, Turk, Shanghai Tianyi, etc. Tiande, Yadeke, KT, Shilin, Seg, Tedia, Balouf, Rogland, Taian, Weilun, Qisheng, Tianzheng, Kailong, Baiyun Mountain, Changhui, Huatong Electromechanical, Tianyu, Xiamen Control, Kangmaosheng, Kaifan Electric, Nengmei, WBSTE, Eton, Huatong, Shilin and so on.
Among them, the circuit breakers of foreign brands are generally of good quality. For example: Schneider, ABB, Siemens, Muller, Legrand, etc., but their prices are generally higher.
There are also many domestic brands of circuit breakers, among which Liangxin, Changshu Switch, Delixi, Zhengtai and Shanghai People's Electrical Appliances are popular in the market. Among them, Liangxin and Constant Switches are relatively better in quality, while others are similar in quality.
Relatively speaking, the circuit breakers with good quality are Schneider, ABB and Siemens, followed by Liangxin and Changshu switches, followed by Delixi, Zhengtai and Shanghai People's Electric Appliances. As far as the cost performance of the circuit breaker is concerned, Liangxin circuit breaker is ok and belongs to the middle end. There are many small brands of circuit breakers in the market, so I won't compare them here because the market is not very popular.
the products produced by chint include? Series of molded case circuit breakers such as NM8, NM6, Record-Mc, NM1, DZ2, NM1 and DZ15; ? DZ2L, NM1LE, DZ15LE series of plastic case leakage circuit breakers; PEOPLE's products have successively passed CCC certification, European CE certification, American UL certification and British KEMA certification, and won the titles of China famous trademark, China famous brand product and national quality award. The company has established Post-Doctoral Research Center, which has been awarded five key projects in Zhejiang Province, namely, high-tech enterprises in Zhejiang Province, three-star enterprises in Zhejiang Province, top 1 electrical industries in China and Zhejiang Province.
the corresponding products produced by tianzheng electric appliance company all have the national compulsory certification license, namely "CCC" certificate. The company has passed ISO91 quality system certification, ISO141 environmental system certification, OHSAS181 occupational health system certification, and some products have passed EU CE safety certification and US UL certification. Tianzheng Electric has always been committed to building a green organization with core competitiveness, always putting the concept of sustainable development into enterprise management and practicing social responsibility with practical actions. We hold a strict and responsible attitude towards customers, shareholders, partners, employees and the public, operate with integrity, win by quality, realize the green and benign development of enterprises through technological upgrading and management innovation, and contribute to a harmonious society.
brands of low-voltage circuit breakers, so much for me to introduce here. If you want to know more, we need to consult more materials. For this kind of engineering specialty, it is rather difficult to understand. We need professional knowledge, extensive knowledge and comprehensive understanding. Low-voltage circuit breakers should be applied to all aspects of our lives. Anything you want to do is applied to your life. Pay more attention, and you may have more professional knowledge.
