Exdb flameproof protection and IP66 enclosure provide explosion-safe operation in hazardous mining zones, while a 30 kW output at 500 V from an 8-pole design ensures strong starting torque and sustained running performance. Business impact: safer installations with compliant protection and predictable torque delivery, enabling you to run haulage and processing lines with confidence. Application: underground and surface mining equipment requiring rugged, explosion-protected motors. The IE3 premium efficiency rating (Full Load around 91.3% at 50 Hz) translates into meaningful energy savings and reduced operating costs across shift cycles. This is especially valuable in energy-intensive mine operations where every percentage point lowers total electricity bills. Application example: conveyors, crushers, and ore processing drives in hazardous areas. The motor’s IMB5/IM3001 mounting, top terminator box, and 250 frame size streamline integration with standard mine plant layouts, reducing installation time and risk. In practice, this means fewer field modifications and faster commissioning. You also gain reliability from a cast iron frame and robust bearings (6315/C3 and 6313/C3) designed for heavy-duty duty cycles in harsh environments, improving uptime and maintenance planning. The D connection configuration and 8-pole, 3-phase design support straightforward electrical matching with existing plant controls, simplifying spare part management and procurement across sites.

FAQs
ABB 3GJM254210-BEK supports IMB5 and IM3001 installation mounting with a top terminator box, designed for frame size 250 and 8-pole configurations. The D connection configuration simplifies electrical wiring, helping technicians integrate the motor into existing mining plant systems with minimal adaptation and fast commissioning.
Exdb flameproof protection indicates explosion-protected equipment suitable for hazardous zones. This aligns with ATEX/IECEx compliance requirements and supports safe operation in underground and surface mining environments, easing regulatory approvals, insurer confidence, and safety protocol adherence.
Yes. The motor is rated for 50 Hz operation with a 500 V supply and is specified for up to 1000 m altitude. It features IP66 enclosure and IE3 efficiency data (Full Load efficiency around 91.3% at 50 Hz), making it suitable for high-altitude, demanding mining sites while maintaining performance.
Maintenance should focus on bearings (6315/C3 and 6313/C3) lubrication and condition monitoring, inspection of the cast iron frame integrity, and verification of the terminator box and cable connections. Regular checks during scheduled downtime help sustain reliable operation in harsh mining environments and extend motor life.
IE3 efficiency at 50 Hz provides higher running efficiency, with Full Load around 91.3%, reducing energy losses compared with older IE2 designs. In continuous mining operations, this translates to noticeable energy cost reductions over time, improved plant uptime, and a favorable total cost of ownership through lower electricity consumption per produced ton.
