The key is to see how this explosion-proof area is partitioned. Explosive gas environments are divided into Zone 0, Zone 1, and Zone 2. Combustible dust areas are divided into zones 20, 21, and 22. The selection of equipment depends on its protection level.

The corresponding device protection levels for Zone 0, Zone 1, and Zone 2 are Ga, Gb, and Gc, respectively

The corresponding equipment protection levels for Zone 20, Zone 21, and Zone 22 are Da, Db, and Dc, respectively

A complete explosion-proof sign will have an equipment protection level. If not, it can also be selected based on the explosion-proof type, such as ia suitable for zone 0/20, zone 1/21, zone 2/22, db suitable for zone 1 and zone 2, etc

You can further communicate with Zhongnuo Testing for specific details!
