Exdb flameproof protection → enhances safety in explosive atmospheres, reducing risk of ignition and enabling compliant operation in mining and chemical processing sites. This protection translates to lower maintenance costs and less downtime due to regulatory setbacks or incident investigations, making it ideal for underground operations and surface facilities where safety is paramount. IP66 enclosure → delivers dependable dust and water ingress protection, improving motor longevity in harsh, dirty environments and enabling outdoor installation or washdown-ready setups on conveyors and grinding systems. IE2 efficiency class → delivers meaningful energy savings under continuous S1 service, lowering operating costs and meeting energy-performance targets across shifting loads common in mineral processing and material handling. 280 frame size and cast-iron frame → provide mechanical robustness and compatibility with common mounting standards, reducing installation time and enabling straightforward retrofits in existing plant infrastructure. Bearings 6316/C3 and IMB3 IM1001 design → support high-load, long-life operation with controlled shaft movement, minimizing bearing maintenance and catastrophic failures during peak mining cycles. Top-terminal box configuration → simplifies electrical connections in restricted spaces and supports safer, faster commissioning in field installations. Altitude tolerance 1000 m and ambient 40 °C → ensure reliable performance in elevated sites and hot environments, reducing the need for derating and enabling broader deployment across global mining operations.

FAQs
The 3GJM283220-ASG uses a 280 framing size with a Cast Iron frame and IMB3 IM1001 mounting class, aligning with common IEC machine footprints. The top-terminator box simplifies wiring in tight spaces, reducing installation time and enabling straightforward retrofits into existing plant layouts while maintaining alignment with standard drive systems.
Exdb protection provides explosion-protected enclosure for motors operating in potentially explosive atmospheres. In mining and underground operations, this minimizes ignition risks from arcing or hot surfaces, supports regulatory compliance, and reduces the likelihood of costly shutdowns due to safety incidents.
Yes. The motor is designed for continuous S1 duty with IE2 efficiency and has been engineered to operate at altitudes up to 1000 meters and ambient temperatures around 40 °C. This combination supports steady, reliable performance in diverse mining sites without frequent derating or cooling concerns.
IE2 efficiency class indicates high energy efficiency under full load, with measured Full Load efficiency around 93.8% and even better under partial loads. This translates to lower electricity costs, improved thermal performance, and reduced total cost of ownership in continuous operation typical of mining and material-handling applications.
Key considerations include a top-terminal box for easy wiring, robust 6316/C3 bearings, and a 280 frame for straightforward coupling to gearboxes or belts. Its Exdb flameproof rating and IP66 protection reduce risk in harsh environments, while its 1000 m altitude tolerance and 40 °C ambient capability minimize derating, contributing to longer intervals between service.
