Description

Shaft height 63–500, from 2 to 16 poles, cast iron frame. Cooling is IC410, IC411, IC416 or IC418, protection degree IP55, IP56, IP65 or IP66. Insulation is class 155 (F) used to 130 (B) or 180 (H) used to 155 (F). Mounting versions are B14, B18, B3, B35, B5, V1, V5, V6 and V18. The motors are ATEX certified, IECEx certification is possible, and the production holds an ATEX quality assurance notification (QAN) and an IECEx QAR report. The manual for enclosed IP55 motors contains a section on installation, connection, protection against impermissible heating and repair of category 2 and 3 machines for zones 1 and 2. The plant has belonged to a larger group since 2011.

How to choose

Power and shaft height are taken from the driven machine, and the Ex db or Ex db eb variant from the terminal box needed. For pumps, compressors, fans and mixers in oil and gas, refining, chemical and pharmaceutical production, fuel stores and other gas-hazardous rooms this series is suitable. The high-voltage KD2 version at 3–11 kV and 180–1320 kW is given as a separate item, and for gas and dust zones at once there is WEX3. The series replace flameproof motors AIM, VA, 2V and VAO.
