ABB’s range of fully-certified aluminium motors for dust ignition and increased safety protection is now extended with frame sizes 160 up to 280.
The aluminium range for explosive atmospheres now includes low voltage motors in frame size from 71 up to 280 (0.25 to 79 kW), offering an alternative to the cast iron range in these frame sizes.
The aluminium frame offers a lightweight alternative for many applications such as grain handling installations where there is a risk of combustible dust. The motor’s smooth surface prevents dust accumulating on the frame, thereby making it easier to clean, resulting in lower costs and improved safety.
The products are certified according to the European ATEX directive 2014/34/EU, and the global IECEx system. The certificates include protection types Ex tb for zone 21 installations where combustible dust is likely to occur, and Ex tc for zone 22 installations where combustible dust only occurs in abnormal conditions.
