Sep 18, 2018

Low voltage circuit breaker is used for AC voltage 1200V, DC voltage 1500V in the circuit to break, control or protection of electrical appliances. Low-voltage circuit breaker is an important part of the electrical industry, in the machinery industry is the basic kit, in the distribution system of low-voltage switchgear is mainly composed of a variety of low-voltage circuit breaker components, low-voltage circuit breaker function and performance of the low-voltage switchgear plays a vital role.

More than 80% of the electricity generated by power generation equipment is allocated through the use of low voltage circuit breakers. Each additional 10,000 kw power generation equipment, about 20,000 pieces of various types of low-voltage circuit breakers with the matching. In the industrial automation system, also need to be composed of low-voltage circuit breaker a variety of control panels, consoles, controllers and other products. China's low voltage circuit breaker industry since 1949 afternoon, is in some repair, assembly simple electrical factory based on the gradual development into an independent design, production industry, to 1979 total production enterprises more than 600, after 1985-1986 years, 1990-1991 years two development peak, 1995 Low-voltage circuit breaker industry has about 1500 production enterprises.
