Exdb flameproof protection is a defining feature that directly enhances safety in hazardous areas, translating into safer startup sequences and reduced ignition risk. This protection is paired with an IP66 enclosure to resist dust and water ingress, making it ideal for harsh underground and outdoor mining environments. Application: installs on 3GJM251210-AEK in IMB3/IM1001 mounting with 500 V power supply for continuous S1 duty across 50 Hz and 60 Hz. IE3 Premium Efficiency delivers measurable energy savings, reducing running costs by aligning motor performance with full-load efficiency around 94% at 50 Hz. This performance supports longer motor life by reducing overheating in continuous operation. Application: suitable for continuous mining processes where energy cost and thermal management are critical. Cast iron frame 250 provides structural rigidity and heat distribution, supporting long service life in rugged mining settings. Premium bearings (6315M/C3 and 6313M/C3) minimize wear and vibration; IMB3/IM1001 mounting ensures straightforward installation on compatible equipment. Application: gear up for IMB3/IM1001 installations in heavy-duty conveyors and pumps. Electrical and duty characteristics support reliable operation: a 2-pole design delivering 55 kW at 500 V, 50 Hz (and suitable across 60 Hz), with S1 continuous duty and Ex protection. With protection class IP66 and insulation ICLF, the motor maintains performance in ambient up to 40 °C at altitudes up to 1000 m. Installation advantages include IMB3/IM1001 mounting compatibility and a rugged, low-maintenance design that reduces lifecycle costs. This is a practical, uptime-focused solution for mining operations.

FAQs
The 3GJM251210-AEK uses IMB3 IM1001 mounting compatibility with a 250 frame size. It features a cast-iron frame, IP66 enclosure, and bearing set 6315M/C3 with NDE 6313M/C3, designed for rugged mining environments and straightforward retrofit onto compatible ABB drives and conveyors.
This motor is rated IE3 and delivers 55 kW at 500 V. Full-load efficiency is approximately 94.3% at 50 Hz (100% load) and about 93.6% at 60 Hz, supporting energy savings in continuous-duty mining operations while maintaining reliable torque.
Yes. The motor features Exdb flameproof protection and IP66 enclosure, specifically designed for hazardous environments in mining. It supports safe operation in explosive atmospheres and meets industry standards for hazardous-area motors, enabling compliant installation on IMB3/IM1001 mounting systems.
Exdb provides flameproof protection for explosive atmospheres, paired with IP66 ingress protection. The motor also carries IE3 efficiency, an insulation class ICLF, and mounting compatibility for IMB3/IM1001, ensuring compliance with ATEX/IECEx requirements in mining installations.
The Exdb flameproof design plus IP66 enclosure reduces risk and downtime in hazardous sites. IE3 efficiency lowers energy consumption, while robust bearings and a cast-iron frame extend service life. Combined, these factors cut maintenance costs, reduce unexpected outages, and improve uptime, delivering a favorable return on investment for mining operations.
