ABB 1HSB495663-2 density relay industrial system ABB controller
At this stage, under the state-owned system, the former Ministry of Machinery Industry organized experts from large state-owned factories to carry out joint design. After the finalization of drawings and type tests are completed, a designated factory will be established and a production license will be issued to a qualified enterprise
To produce these products.

Personally, I always thought that the rise of Wenzhou Electric Appliance had a sense of helplessness. At that time, on the one hand, the market voice was growing, and on the other hand, 1HSB495663-2, a smart and business minded person, was
It is regarded as a delusion to be self-employed and obtain permission to formally produce products.
To some extent, it is the oppression of this system that makes Wenzhou enterprises embark on the path of original sin of “recycling old goods, refurbishing sales, and counterfeiting”.
To this day, these enterprises, which often have tens of thousands of square meters of factory buildings and contain top manufacturing equipment, are still making atonement for yesterday’s mistakes.
The last glory of this era left me with the memory that in the Tian’anmen celebration project of Hong Kong’s return in 1997, the DZ20 switch was still used in the square lighting and the power supply equipment of Jinshuihe.
The Development of Molded Case Circuit Breaker: Personal Observation Version Phase II
Phase II: Jiaxing Electric Control and Changshu
1HSB495663-2 Although almost nobody knows that the former has declined in recent years, when it comes to low-voltage electrical appliances in China, the two units personally think it is a milestone.
The TO TG series products of the former were introduced from Ishizaki, Japan. In the era when the 225 shell frame switch was more than 30 cm long, the size of this series of products was nearly reduced by half, which sounded the imitation of the Soviet Union
Product DZ20, DZ10, etc.
Changshu, Teacher Tang Chunchao.
With CM1 series products copied from Mitsubishi, Japan, the design institutes shuttled from north to south, from east to west. At that time, the transformer capacity began to increase gradually. Accordingly, the demand for molded case circuit breakers with higher breaking capacity became increasingly urgent
Cut. The economic take-off has brought about a rapid growth in electricity consumption. This trend has made Changshu a success and brought the third generation of molded case circuit breakers in China.
By the way, the design institute was pushed to the front of the market at that time. It has become one of the main players in the market of low-voltage electrical appliances.
The picture fee… seems to have started at this time
Stage 3: The world of Mitsubishi
Mitsubishi NF series molded case circuit breakers, which have been copied in China, are produced by Changshu, Beijing People’s Electrical Appliance Factory, Tianjin Low Voltage Electrical Appliance Factory, and Zunyi Changzheng No. 9 Factory. And later the river of Hangzhou. It seems that the people of Shanghai always
Delayed in the production of contactors and thermal relays approved by ABB, and then quietly manufactured circuit breakers similar to Schneider’s NS series products.
When the market is big, Schneider, ABB, Siemens, Muller, Hager and Qisheng from abroad will come.
Mitsubishi, I have always been a bit gloating. It seems that this Japanese unit has not entered the mainstream of the formal market.
However, it cannot be denied that his products, like the later PSS series plastic shells, are still somewhat NB in the world
No matter how much I hate the island country on the other side of the ocean, the mainstream domestic molded case circuit breakers are basically imitated from Mitsubishi products, which cannot be denied.
It was a time of easy business.
The motherland has a vast territory, leading to the upgrading of products from economically developed regions to underdeveloped regions. This gradient allows Wenzhou enterprises to become second, third, and even fourth and fifth tier cities relying on terminals,
Grasping the longer long tail market, rapidly accumulating funds and expanding enterprises.
The state has issued a document to stop DZ10 and later DZ20, but they continue to manufacture these products with great enthusiasm. The reason is simple, because two thirds of the vast motherland is mountainous, with more than 1 billion people
affluent. According to the point on the upper outline, they have narrowed the gap between the east and west and between urban and rural areas. Compared with the policy makers sitting in the air-conditioned luxury office, these Wenzhou enterprises have not forgotten those who lag behind the economy
An area of economic progress.
Based on this, I would like to pay tribute to these businessmen who leave their hometown, no matter what motivates them to do this.
A little sensational, but also a bit off topic.
What I wanted to say was that Chint’s NM1, Delixi’s CDM1 and Huanyu’s HUM series were all imitated from Mitsubishi.
Phase IV: component factory: no saturation, only more
More component factories, more products, more products, more intense homogenization ratio
