ABB M2JA Flameproof & M3GP Hazardous Area Motors
The ABB M2JA and M3GP Explosion-Proof Motor Series (featured model: M2JA 160M4A 11 kW Ex d IIC T4 Gb) are ABB's certified hazardous area low voltage induction motor solutions, engineered specifically for explosive gas, vapor, dust, and harsh chemical processing environments. The **M2JA Series** features a heavy-duty flameproof enclosure rated **Ex d / Ex db IIC T4 Gb** (Zone 1 and Zone 2 gas atmospheres), preventing internal ignitions from propagating to the external ambient environment. The **M3GP Series** belongs to ABB's high-efficiency process performance family, offering flexible certified protection modes including **Ex ec II T3 Gc** (Non-Sparking Zone 2) and **Ex tb / Ex tc IIIC** (Dust-Ignition Proof Zone 21 & Zone 22). Covering power output ratings from 0.25 kW up to 1000 kW across IEC frame sizes 80 to 450, ABB hazardous area motors carry full international certification including **ATEX, IECEx, and CCC Ex (China)**, featuring VFD-rated insulation systems for variable speed duty with **ABB ACS580 and ACS880 drives** in oil refineries, offshore platforms, chemical reactors, grain elevators, and pharmaceutical plants.
