Hazardous Location Base-Mount AC Motors



These motors are rated for environments where hazardous material is present. They are continuous duty and mount horizontally. You can wire for clockwise or counterclockwise rotation; instructions are included. The base is welded to the enclosure.
Motors with automatic overload protection turn off in overload conditions to prevent motor damage and start automatically after they cool.
Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment.
