Exdb flameproof protection enhances safe operation in hazardous areas, while IP66 rating protects against dust and water ingress. Business impact: lower incident risk and reduced maintenance interruptions in mining conveyors and crushers. Application: ideal for Ex zones in underground operations where reliability is essential. The cast-iron frame (250) with 6315/C3 bearings delivers rugged longevity and easier field servicing, reducing total cost of ownership. This translates to fewer unscheduled outages and extended service life on tough terrain. The IE2 efficiency profile with 94.9% full-load performance enables measurable energy savings across running hours, supporting green initiatives and lower operating costs in large installations. Application emphasis: long-term energy reliability for bulk material handling and processing.

FAQs
For hazardous zones, install the Exdb flameproof motor with the IP66 enclosure and Ex protections intact. Use the top-mounted terminal box for straightforward wiring, verify mounting per IMB3 IM1001 class, and ensure adequate clearance for cooling and maintenance. Plan for a 1000 m altitude and 40 °C ambient limits to avoid derating.
Exdb protection enables safe operation in explosive atmospheres by containing any internal faults. This reduces ignition risk and facilitates compliance with mining safety standards. Maintenance intervals are driven by robust bearings and a cast iron frame, with gasketed seals and accessible terminal box simplifying on-site servicing.
Yes. The motor is a 4-pole design with IE2 efficiency, delivering Full Load efficiency around 94.9%, with 75% load at 95.2% and 50% load at 94.9%. This supports consistent speed control in conveyors and crushers while lowering energy costs across duty cycles common in mining operations.
The ABB 3GJM252230-ASG is tailored for mining, especially underground and surface operations, as well as other hazardous-zone equipment like heavy-duty conveyors and processing lines. Its flameproof Exd protection, IP66, and rugged frame suit environments with dust, moisture, and variable loading conditions.
Expect energy savings from IE2 efficiency, reduced downtime due to robust bearings and IP66 protection, and lower maintenance costs from a durable cast-iron frame. In mining deployments, these factors compound to shorten payback periods while extending service life and improving overall equipment availability.
