What is the relationship between explosion protection rating and motors?
Thread Content
All motors are marked with an explosion-proof rating, so are there any differences between motors with different explosion-proof ratings? For example, are there any differences between the motors of dII BT4 and dII CT4?
There is definitely a difference. The CT4 has a higher explosion protection rating than the BT4; they look similar on the outside, but the BT4 has explosion protection class B while the CT4 has class C. For hydrogen, acetylene, and carbon disulfide, dIICT4 must be used; for other types of gases, dIIBT4 can be used as a substitute. It depends on the usage scenario.
Different explosion protection ratings are suitable for different environments. With the specific Baidu explosion-proof ratings, everything becomes clear. It’s not clear what the specific differences in the equipment are.
One is grade B and the other is grade C; you can find out by searching online. It depends on the environment in which you are working – generally grade B is sufficient, but grade C is required when hydrogen or similar substances are involved.
The Nanyang samples should all come with instructions; they’re available on the official website: lol
I mean, motors with two different explosion protection ratings are also different, right?

Do you mean the same thing by “different,” referring to the appearance? Or?
d is the explosion-proof symbol； ⅡB can be applied in environments with explosive mixtures formed by Class ⅡB gases and air ； The explosion protection classification is mainly divided into Class I (for use in mines) and Class II (for use in factories). Category II is further divided into: IIA, IIB, IIC (safety level: A
The structure, or rather, the price. . . .
