ABB high voltage explosion-proof motors
ABB high-voltage explosion-proof motors are the safe choice for potentially explosive atmospheres. Our explosion-proof motors are designed to withstand the pressure of an internal explosion without damage, and to prevent the spread of flames outside the enclosure.
Explosion-proof motors are based on reliable designs and offer high productivity under demanding conditions. Our explosion-proof motors combine the advantages of compact size with high power density, high efficiency and safety. Explosion-proof motors are designed to operate reliably in harsh environments such as extreme temperatures, corrosive dust and humidity.
Our explosion-proof motors are certified for gas groups IIB and IIC and meet all relevant international standards, including IEC, European (EN) and ATEX, as well as the most important specifications of the oil and gas industry.
- Safe choice for potentially explosive atmospheres
- Certified for gas groups IIB and IIC
- Developed to meet the requirements of key specifications
- Compact solution with best-in-class power density
- Explosion-proof motors require no additional piping at the factory
