Low voltage flameproof motors

ABB low 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.

Flameproof motors are based on reliable designs and provide high productivity in demanding conditions. Our flameproof motors combine the benefits of safety, high efficiency and sustainability. They are designed to operate reliably in harsh environments such as in extreme temperatures, corrosive dust and humidity.

Our flameproof motors are certified for gas groups IIB and IIC and meet all relevant international standards, including IEC, European (EN) and ATEX and the most important specifications for the oil, gas and chemical industries.
