How should explosion-proof electrical equipment be selected- Shenzhen Zhongnuo Testing

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

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

The equipment protection levels corresponding to zones 20, 21, and 22 are Da, Db, and Dc, respectively

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

You can further communicate with Zhongnuo Testing for specific details!
