Description
WEG Explosion-proof motor was especially designed to operate in environments with the presence of explosive atmospheres. It has 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 Division I/Zone 1. Motors are certified for VFD service.
