SIEMENS SIMOTICS XP covers classes:
Zone 21: 2D Ex tb (Db)
An area in which it is expected that an explosive gas atmosphere comprising a dust-air mixture will be present occasionally during normal operation.
Zone 22: 3D Ex tc (Dc)
An area in which it is expected that an explosive gas atmosphere in the form of a cloud of combustible dust in air will be present only rarely and then only for a short period during normal operation.
Zone 2: 3G Ex ec (Gc)
An area in which it is expected that an explosive gas atmosphere will be present only rarely and then only for a short period during normal operation.
Zone 1: 2G Ex eb (Gb)
An area in which it is expected that an explosive gas atmosphere will be present occasionally during normal operation
Zone 1: 2G Ex db (Gb)
An area in which it is expected that an explosive gas atmosphere will be present occasionally during normal operation
Application:
The explosion-protected motors are used in the following sectors to prevent explosion hazards that result in serious injury to persons and severe damage to equipment.
- Chemical and petrochemical industry
- Production of mineral oil and gas
- Gas works
- Gas utility companies
- Gas stations
- Coking plants
- Mills (e.g. grain, solids)
- Sewage treatment plants
- Wood processing (e.g. sawdust, tree resin)
- Other industries subject to explosion hazards

Technology overview:
Motors siemens simotics xp comply with European Directive 2014/34/EU (ATEX): As an alternative to the European directive, certificates for IECEx (Australia), EACEx (Eurasian) and CCCEx (China) are also available.
Warning:
special motor configuration and certified thermal protection of the windings is required in case of inverter supply
