Exdb flameproof protection paired with an IP66 enclosure delivers safety and regulatory compliance for mining and other explosive environments. The design reduces the risk of ignition and enables installation in underground conveyors, crushers, and processing lines. In practice, this means fewer shutdowns due to protective concerns and a smoother procurement path for hazardous-area projects. IE2 energy efficiency at full-load 94.2% translates to meaningful operating cost reductions across long shifts. The motor’s continuous-duty S1 rating supports steady performance in demanding loads while meeting IEC/CE requirements. This combination lowers energy bills without compromising torque and starting performance during peak demand. Built for harsh conditions, the motor operates reliably at 40 °C ambient temperature and up to 1000 m altitude, with IC411 insulation handling thermal stress. The IP66 protection guards against dust and water ingress, making it suitable for dusty mines and outdoor installations. Such resilience minimizes spare parts consumption and extends service intervals. Cast iron frame, 250 frame size, and precision bearings give excellent mechanical rigidity and vibration damping. The IMB5 IM3001 class supports precise mounting and safe coupling with drives, while a top-terminator box simplifies wiring and field service. These features reduce installation time and improve uptime in plant-wide motor fleets. Designed for global procurement, the unit ships with a reliable Finnish origin and standard ABB build quality. With Exdb protection and flameproof certification, it fits mining and heavy industry guidelines while maintaining spare parts compatibility across models. The motor’s 2-pole design and rotation in both directions offer installation flexibility and easier alignment with existing drive systems.

FAQs
For mining applications, install the 3GJM251210-BEG with a top termination box and in a location that accommodates its Exdb flameproof protection and IP66 enclosure. Ensure mounting supports a 250 frame, cast iron construction, and that the environment meets ambient temperature up to 40 °C and altitude up to 1000 m. Verify rotation direction on both sides and plan for routine inspection of bearings (6315M/C3 / 6313M/C3) and IC411 insulation to maintain safe operation in hazardous zones.
IE2 efficiency improves energy utilization during continuous-duty operation (S1), delivering measurable savings on electricity bills over long runtimes. Full-load performance is rated at about 94.2%, reducing heat load and cooling requirements in plants. For procurement, this translates to lower total cost of ownership and a smaller environmental footprint without sacrificing torque or startup performance.
Yes. The ABB 3GJM251210-BEG features Exdb flameproof protection and is designed for hazardous-area use. Its IP66 enclosure, IC411 insulation, and S1 duty rating support safe continuous operation in mining and similar environments. Always ensure compliance with local standards and verify that installation aligns with Exd/Exdb guidelines and site-specific safety requirements.
The motor uses a top terminator/wiring box for straightforward electrical connections, simplifying field wiring in constrained spaces. The 2-pole design and rotation capability in both directions offer flexible alignment with existing drives. Cast iron frame size 250 provides robust support, while high-precision bearings reduce vibration. This configuration enables quicker commissioning and easier future maintenance.
Maintenance benefits come from a rugged cast iron frame, durable bearings (6315M/C3 and 6313M/C3), and a sealed IP66 enclosure that reduces ingress-related wear. The Exdb flameproof protection minimizes protective downtime in hazardous environments, while IE2 efficiency lowers energy-related wear and thermal stress. Finnish origin and standardized design also streamline spare-parts availability and global service support.
