How to put it, there is no such thing as fake. It can only be said that they are similar products, with high-end and low-end products. ABB, Siemens, and Schneider are the best, considered high-end products, and they are also the most expensive. It seems that ABB is the most expensive among the three. Chint and Delixi are domestic products. They are considered low-end products and are also the cheapest. The price of an ABB circuit breaker is equivalent to 4 to 5 times the price of Chint. There are also those things about Merlin Gerin, which are probably just a side shot. Among these Meilan Gerin, Tianjin Meilan Gerin is the best, which is now Schneider's. It can be said that there is no such brand of Tianjin Meilan Gerin anymore. There are other types of Merlin Gerin. As far as I know, the quality of Suzhou Merlin Gerin is still good. It is considered a mid-range product, and the price is half of Schneider’s. There are also some other Merlin Gerin, most of which are OEM, that is, their products are made in other places, and when they are shipped to this place and marked with a mark, they are said to be the Merlin Gerin of this place.
