Exdb flameproof protection paired with an IP66 enclosure provides intrinsic safety in dusty, humid mining environments. This combination reduces ignition risk and minimizes unplanned downtime caused by damaged enclosures or ingress. The motor is suitable for 3GJM IE3 efficiency targets in demanding drives such as conveyors and crushers. High IE3 efficiency translates into tangible energy savings across full and partial load conditions. For 50 Hz operation, full-load efficiency is 92.2% with 75% and 50% loads just above 90.7%, delivering lower operating costs. At 60 Hz, the motor maintains 92.4% full-load efficiency and strong partial-load performance, supporting variable duty cycles common in mining setups. Rugged mechanical design supports long service life in harsh environments. Frame 280 is cast iron, with 6316/C3 bearings and IMB5/IM3001 mounting, while the top terminator box simplifies field wiring and reduces installation time. These features also enable easier retrofits and spare-part planning. Electrical configuration and duty are aligned with industry practices: 400 V, 50 Hz input, 8 poles, and D connection, with S1 duty and IP66/ICLF protection. The unit is rated for up to 1000 m altitude and 40 °C ambient, ensuring reliable performance in surface or underground installations. Overall, ABB's 3GJM284220-BDK delivers safety, efficiency, and reliability while supporting mining standards and maintenance economics.

FAQs
The motor is designed for IMB5 IM3001 mounting and uses a top terminator box for simplified wiring. This combination enables quick field installation, easier access for maintenance, and straightforward retrofits into existing mining drives or processing lines.
Electrical data include 400 V input with 50 Hz and 60 Hz operation. It delivers 45 kW with IE3 efficiency; 50 Hz full-load efficiency is 92.2% (with 75%/50% loads around 92.1–90.7%), and at 60 Hz full-load efficiency is 92.4% (partial loads around 92.1% and 90.5%), supporting energy savings across duty cycles.
Yes. It is a flameproof Exdb protected motor rated for hazardous locations, with IP66 enclosure, IC411 insulation, and S1 duty. The 8-pole design and IMB5/IM3001 mounting are optimized for underground and surface mining drives, conveyors, and material-handling equipment.
The motor features Exdb flameproof protection, IP66 enclosure, and IC411 insulation. It is built for hazardous environments prevalent in mining, meeting protection and safety standards while maintaining high efficiency (IE3) across 50 Hz and 60 Hz supply.
Robust cast-iron frame, durable bearings (6316/C3), andトップ terminator wiring enable longer service intervals and simpler spares management. The IE3 efficiency reduces energy costs over the motor’s life, delivering a favorable total cost of ownership in heavy-duty mining and processing applications.
