Some people think that the explosion-proof level of CT4 is higher.. can withstand the temperature of 450 degrees without deformation or something?

Some people think that the explosion-proof level of CT6 is higher, and the surface of the component can only produce a temperature below 85 degrees. It will not ignite the surrounding gas

What does the maximum temperature allowed on the surface of the component mean?

Answer: T6 and T4 refer to the surface temperature of explosion-proof products when they work, not the temperature they withstand. The surface temperature of T6 group products is lower than that of T4 group, and of course the T6 group is better. For example, if you buy a TV, of course you want the surface temperature to not be too high when it is on. Explosion-proof products are also a reason, and the surface temperature is lower when working, which is safer. The surface temperature of T4 is allowed to be 135 degrees, and the surface temperature of T6 is 85 degrees, which has higher technical requirements for explosion-proof equipment
