ABB 3GJM281220-BDL Flameproof IE3 Mining Motor Exdb IP66

Flameproof Exdb protection is engineered into the ABB 3GJM281220-BDL to safeguard personnel and assets in volatile mining zones. This protection, paired with an IP66 enclosure, minimizes dust and water ingress, supporting reliable operation in harsh environments. The unit’s IMB5/IM3001 mounting compatibility and D-end top termination streamline installation in tight spaces and simplify future service. IE3 premium efficiency delivers measurable energy savings across continuous duty. With 75 kW output at 400 V and 50 Hz, the motor reduces energy consumption while maintaining full-load performance. Operators benefit from lower running costs, improved heat management, and a reduced carbon footprint without compromising uptime in S1 duty. A rugged mechanical package reinforces durability in demanding mining applications. The 280 frame, cast iron construction, and 6316/C3 bearings provide long service life under heavy loads and frequent starts. The design supports operation up to 1000 m altitude and 40 °C ambient, ensuring reliable performance in elevated, hot sites. Electrical robustness is embedded in the design. It runs on 400 V at 50 Hz with a 2-pole configuration and D connection, optimized for standard mine power distributions. The motor’s IC411 insulation class with insulation level ICLF plus Exdb protection ensures reliable operation in hot, dusty underground environments while maintaining safe start-up in cold conditions. Maintenance and serviceability are enhanced by a cast-iron frame and readily available spare parts. The 280 frame size, bearings 6316/C3, and IMB5/IM3001 mounting support straightforward alignment and bearing replacement. Finland-origin manufacturing adds traceability and consistent QA, reducing risk during long-term operation and ensuring predictable lifecycle costs.
