Description
The marking II 2G Ex db IIB/IIC T4/T5 Gb and II 2G Ex db eb IIB/IIC T4/T5 Gb is supplemented by enclosure protection against dust ignition Ex tb and Ex tc IIIB/IIIC T130 °C. Shaft height 80–355, 2–16 poles, cast iron frame with self-ventilation IC411, protection degree IP55, IP56 or IP65. Insulation is class 155 (F) used to 130 (B) or 180 (H) used to 155 (F). Mounting B3, B34, B35, B5, B14, V1, other versions on request. The motors are ATEX certified, and IECEx certification is possible. The voltage range up to 1140 V makes it possible to use them in mine networks. The plant has belonged to a larger group since 2011.
How to choose
If both gas and dust protection are needed in one motor, choose WEX3, and if only zone 1 gas up to 800 kW, look at KD1 / KD2. The series is suitable for pumps, fans, compressors, conveyors and mixers in oil and gas, chemical, pharmaceutical, flour milling, sugar and woodworking plants, in grain stores and at mining enterprises. It replaces explosion-protected motors AIM, AIU, VA and mine motors for 660/1140 V.
