The WEG 21 includes a robust construction, a flame retention system with gaps between the parts carefully designed, accurate machining on the terminal box and screws with high mechanical strength. It meets the requirements of explosive atmospheres like Zone 1 and Zone 2.
WEG explosion-proof motors feature a protection system that confines parts able to ignite an explosive atmosphere in an enclosure capable to withstand an internal explosion without allowing propagation to the external environment.
