U.S. MOTORS Hazardous Location AC Motor

Class 1 C, D/2 E, F, G three-phase hazardous location AC motors don't require starting capacitors, run capacitors, or centrifugal starting switches that can wear out and fail. They operate with a higher torque and greater efficiency than single-phase hazardous location motors of the same HP, rpm, and frame size. These motors are for use in environments where flammable gas or vapor such as ethylene, propane, or methane are present. They are also for use in areas where combustible metal dusts such as magnesium, and other combustible dusts such as carbon black, coke, charcoal, flour, starch, or grain dust are present.
