Why does the type of explosion-proof certificate not correspond?
When many customers see the explosion-proof certificate, they will feel why the specifications and models do not correspond to the motor products they want, and whether they are sent wrong.
For example, model :YBX3-160M-4 11kw 380V BT4 explosion-proof grade
We will receive the following explosion-proof certificates:
YBX3-160M explosion-proof certificate
We can see that the specification and model are written: YBX3-160L-4 15KW 660/1140V and the YBX3-160M-4 11kw 380V BT4 explosion-proof motor we need are not the same model.
In fact, this is a misunderstanding, many only see the model specifications do not fully understand the content of the documents, explosion-proof documents are not issued in accordance with the specific model, but the motor with the same frame number is the same explosion-proof documents.
We all know that explosion-proof motors will be combined into a variety of different motors according to different speeds and different powers, and their specifications and models are different with different speeds of the same power. For example, YBX3-160M-4 11kw and YBX3-160M1-2 11kw
The same 11kw, the two different speeds of their specifications are not the same. In order to meet different power needs, the explosion-proof certificate of the motor is divided according to the frame number, the same frame number in different speed, different power or different voltage, as long as they are used in the same frame number is an explosion-proof certificate.
These specific models and contents are written in the notes at the bottom of the certificate.
