High Voltage Flameproof Motors

Industry-leading flameproof motors for extreme working environments

ABB high voltage flameproof motors are a safe choice for potentially explosive atmospheres. Our flameproof motors are designed to withstand the pressure caused by an internal explosion without incurring any damage as well as prevent flame propagation outside of the enclosure.

• Safe choice for potentially explosive atmospheres

• Certified for gas groups IIB and IIC

• Developed to comply with the requirements of the main specifications

• Compact solution with best in class power density

• Flameproof motors do not require additional piping at plant
