Marathon three-phase hazardous location AC motors do not require starting capacitors, run capacitors or centrifugal starting switches, all of which can wear out and fail. They have more torque and efficiency than single-phase hazardous location motors.

A totally enclosed fan-cooled (TEFC) motor has a frame that prevents air exchange between the inside and outside of the motor. This prevents airborne contamination and to a lesser extent, liquids from entering the motor. An external fan blows air over the frame to cool the motor, and the frame is ribbed to increase the surface area for heat dissipation.
Division 1 is a subset of Class I. It is defined as an area where explosive or flammable gases, vapours or liquids can exist under normal, everyday operating conditions.
These motors are intended for environments where flammable vapours or gases (such as propane, ethylene & methane) are present. These explosion-proof motors are also suitable for areas with combustible dust (charcoal / carbon black / grain dust).
