Why does the type of explosion-proof certificate not correspond?

When many customers see the explosion-proof certificate, they will immediately think why the specifications and models do not correspond to the motor products they want, and whether they have sent the wrong ones.

For example: ybx3-160m-4 11kw 380V BT4 flameproof grade

We will receive the following anti-explosion certificates:

YBX3-160 - m explosion-proof certificate

We can see that the specification and model are written as follows: ybx3-160l-4 15KW 660/1140v is not the same model as the ybx3-160m-4 11kw 380V BT4 explosion-proof motor we need.

In fact, this is a mistake, many only saw the model specifications did not fully to understand the content of the certificate, the certificate is not issued in accordance with the specific model, but the motor with the same frame number is the same explosion-proof certificate.

We all know that explosion-proof motors can be combined into different motors according to different speeds and powers. Different speeds of the same power can make different specifications and models.For example: ybx3-160m-4 11kw and ybx3-160m1-2 11kw

The same 11kw, two different speeds and their specifications are different.In order to meet the different power demand, the motor explosion proof certificate is divided according to the frame number, the same frame number in different speed, different power, different voltage, as long as they are in the same frame number with an explosion proof certificate.

These specific types and contents are written in the record below the certificate.

Please see the red mark in the picture below for details.
