ABB 3GJM252220-AEG 3-Phase Squirrel Cage Motor - Exdb

Exdb explosion protection enables safe operation in hazardous areas by flameproof enclosure design. This capability reduces ignition risk and supports compliance with hazardous-area regulations, delivering a clear safety and insurance advantage. Application examples include underground mining, chemical processing, and other environments where ignition sources must be controlled. IP66 enclosure rating provides robust protection against dust intrusion and water exposure. The business impact is longer intervals between maintenance, lower wear on seals and bearings, and improved uptime in dusty or wet installations. This makes the motor well-suited for conveyors, crushers, and processing lines in mining, metals, and bulk-material handling sectors. IE1 efficiency around 93.8 to 94.2 percent across full and partial loads translates into tangible energy savings during continuous-duty operation. The result is cooler running temperatures, reduced cooling requirements, and lower energy bills over the motor lifecycle. Practical applications include long conveyor runs, grinding mills, mixers, and other heavy-load processes where stable torque matters. Cast Iron frame size 250 provides exceptional mechanical rigidity and vibration damping for demanding service. The 6315/C3 bearings, IMB3 IM1001 mounting class, and a top-ported terminator box contribute to long bearing life and straightforward maintenance. With a 4-pole configuration and S1 continuous duty, the motor maintains consistent speed and torque in high-demand mining and processing lines, even at altitude up to 1000 meters. Directional flexibility—rotation on both sides and a top-placed terminator box—simplifies on-site installation and retrofits into existing layouts. The motor is compatible with standard ABB control gear and drives, enabling quick integration into current automation architectures. This reduces commissioning time and spare-parts inventories, delivering faster time-to-value in projects and continuous production. Operational reliability is supported by rugged construction, well-documented safeguards, and predictable IE1 performance under variable loads. The Exdb protection paired with IP66 and IC411 insulation delivers a robust, compliant solution for harsh environments. For OEMs and end-users, this translates to lower total cost of ownership, higher uptime, and a clear path to scalable mining and mineral-processing deployments.
