The products meet the requirements of the GB18613-2020 efficiency of energy efficiency grade 3. The series products introduce Siemens design technology with excellent performance, safe and reliable to use, low vibration, low noise, and meet environmental protection requirements. Its production equipments adopt advanced CNC machine tool equipment, citing Siemens advanced insulation structure design and manufacturing process, use high quality cold rolled silicon steel sheet and high quality bearing with strict quality control. Beide 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. Beide dust explosion-proof motor’s performance fulfill GB/T 3836.1-2021《Explosive atmospheres-Part I: Equipment General requirements》and GB/T 3836.31-2021《Explosive atmospheresPart 31: Equipment dust ignition protection by enclosure "t"》, suitable for explosive dust environment Zone 21 or zone 22.西门子电机（中国）有限公司 10 噪声 Noise levels 噪声值 噪声值根据 DIN EN ISO 1680 标准在噪音室测得。表面声压级 噪声Lpfa 计算表示单位为 dB（A）。声压级噪声的空间平均值 是在其测量面上测得的。测量面是距离电机1米的测量包络面。 声功率级噪声用 LWA 来表示，单位为 dB（A）。噪音值见选型 数据表，选型数据表中的噪声值仅适用于全封闭自扇冷却（冷 却方式：IC411）。电动机在 50 Hz 电源供电空载运行时，噪音 容差为 +3 dB。当在 60 Hz 电源下空载运行时，噪音容差大约为 +4 dB。 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.
