The explosion-proof motors are often used in the following industries to prevent explosion hazards that result in serious injury to persons and severe damage to property.
• Chemical and petrochemical industry
• Production of mineral oil and gas
• Gas works
• Gas supply companies
• Petrol stations
• Coking plants
• Mills (e.g. corn, solids)
• Sewage treatment plants
• Wood processing (e.g. sawdust, tree resin)
• Other industries subject to explosion hazards

Siemens series high efficiency dust explosion-proof three-phase asynchronous motor is totally enclosed, self-fan cooled high efficiency motor. The products meet the requirements of the GB18613-2012 efficiency of energy efficiency grade 2.
Dust explosion-proof motor can be used for food or forage machine, wood machine, flour machine or storage, as well metal, chemicals, synthetic resin, agricultural products and all kinds of combustible dust places such as fiber, fuel and so on. Detailed types of dust refer to "dust characteristics example," but this series motors are not suitable for gas or underground coal mine with combustible dust and coal mine ground device with electrical
equipment, also can't be used in place with explosive dust and spontaneous combustion substances (e.g. phosphorus powder) but can burn without oxygen from the atmosphere.
Siemens dust explosion-proof motor's performance fulfill GB 12476.1-2013 "Combustible dust environment for electrical equipment -part 1: General requirements" and GB 12476.5- 2013 "Combustible dust environment for electrical equipment - Part 5: Housing protection type" tD "", suitable for explosive dust environment Zone 21 or zone 22.
§§ Environmental
•Degrees of motor protection IP65 (IEC 60034-5);
•Altitude shall not exceed 1000m above sea-level (IEC 60034-1);
•Allowed air temperature between -20 ºC and 40 ºC (IEC 60034-1);
•Permitted relative humidity:
-20 ºC ≤ T ≤ 20 ºC:100 %
20 ºC < T ≤ 30 ºC:95 %
30 ºC < T ≤ 40 ºC:55 %
For higher coolant temperatures and / or site altitudes higher than 1000 m above sea level, the specified motor output must be reduced by using the factor kHT. The results in an admissible output (Padm) of the motor:
Padm = Prated • kHT
§§ Noise Levels
Noise levels for mains-fed operation
The noise levels are measured in accordance with DIN EN ISO 1680 in a anechoic room. It is specified as the A-valued measuring-surface sound pressure level Lpfa in dB (A). This is the spatial mean value of the sound pressure levels measured on the measuring surface. The measuring surface is a cube 1 m away from the motor surface. The sound power level is also specified as LWA in dB (A). Please find the noise value in technical data table, the specified values are only valid for totally enclosed fan cooling (cooling method: IC411) motor with no load at 50 Hz with no
load, and the tolerance is +3 dB. While motor operating 60 Hz with no load, the values are approximately +4 dB (A) higher.
§§ Vibration
The rotors are dynamically balanced to severity grade A using a half key. Table below contains the effective vibration values for unloaded motors. Vibration grade B can be provided as option.
