What products are ABB's strengths? What about Omron? Schneider? Siemens?

In terms of power transmission and distribution, ABB's advantageous products are low-voltage circuit breakers (VD4, E, F, T, S), that are very cattle, in industrial control, its frequency conversion, soft start is also very good, especially their energy-saving slogan, of course, other electrical equipment they are also involved in; OMRON sensors have their own specialties; Schneider and ABB belong to the brotherhood of competing categories, in the power transmission and distribution of two very competitive and occupy a large market share in the world. In terms of 2 fierce competition and occupy a large market share in the world, so Schneider both low and medium-voltage circuit breakers (which low-voltage circuit breakers and according to the actual situation in China launched a series of specialized) and industrial control have their own very good products, the same, other products are also involved; Siemens, although there are also in the transmission and distribution of the product is their protection (the legend of the MV relay protection), and is their PLC ), there is their PLC and other industrial control products, their own summary, I hope useful!
