As an Explosion Proof Power Distribution Box Supplier, ACCEL TECHNOLOGY will give you a few tips on explosion protection.
1. Division of hazardous areas
The meaning of a hazardous area is a measure of the likelihood of actual danger in the area, thereby specifying the applicable explosion protection type. The explosion-proof area of the International Electrotechnical Commission/European Electrotechnical Commission is:
Zone 0: continuously present areas with a hazard greater than 1000 hours/year;
Zone 1: Areas with intermittent dangers of 10~1000 hours/year;
Zone 2: The area of danger in the event of an accident of 0.1 to 10 hours per year;
2. Explosion protection mark
The following is an example of the CENELEC hydrogen explosion-proof mark: E Ex ia IIC T4
E: Approved according to the CENELEC logo
Ex: Explosion-proof public sign
Ia: Explosion-proof type (intrinsically safe)
II: Equipment group
C: gas group
T4: temperature group
