Weekly Question: Low-voltage power distribution – Low-voltage circuit breakers
Thread Content
Regarding low-voltage electrical appliances: Let’s start with the most basic circuit breaker today. I’ve been in this field for a few years now. But the yard is too small. No one is communicating. . It’s too closed off. Let me start by offering some initial ideas to stimulate further discussion. Here, the clients mostly use the earliest version from Schneider, and later on Siemens. Recent ABB. . These 3 models also have their own strengths among imported brands. Schneider does well in the low-voltage market. I don’t know much about Siemens. . ABB is essentially the leader in the entire industry, and it has increased its efforts to develop the Chinese market in recent years. The performance-to-price ratio is not very good, in my opinion. . After all, it’s just about design. . I hope everyone will come and discuss it. . If I’m online, I’ll come and help you score points~! ~! :P;P Also, I’d like to ask how to set a nickname. . . :'(
In my opinion, users choose these imported brand circuit breakers for higher-end applications; the ABB brand circuit breakers are the most commonly used, while those from Siemens seem to be used less often. Its main advantage is high reliability, with mechanical and electrical performance that exceeds that of top domestic brands.
For larger ones, we use Changshu and Changzheng; for smaller ones, we use Chint. ABB’s ones are available too. All of them can
For low-voltage incoming line circuit breakers, imported brands such as ABB or Schneider are generally preferred; for other less critical loads, domestic DW series products can also be used.
I work in design; I’m not very familiar with applications. I’m not sure what the main differences and advantages are between imported brands and mainstream domestic brands. It would be best to provide some reference data. . . Like the price? Maintenance? Performance
It seems that the market for low-voltage electrical equipment is not easy to operate in at the moment. The competition is extremely fierce. I don’t know which direction it will take from here.
We use Japanese brands quite often; FUJI and Mitsubishi are good options. Brands like Siemens, ABB, Schneider, and AB are also widely used, and they’re excellent as well.
Why not use domestic ones? I think domestic products are quite good these days as well.
