ABB 3GJM284220-BEG 3-Phase squirrel cage motor - Exdb
Part Number: 3GJM284220-BEG
Quick Summary
ABB 3GJM284220-BEG 3-Phase squirrel cage motor for hazardous-area applications. Engineers often struggle to source explosion-rated motors that deliver safety, reliability, and efficiency in demanding mining environments. This model integrates Exdb flameproof protection, IP66 enclosure, and ICLF insulation with IE2 efficiency, supporting continuous S1 duty in tough conditions. The combination helps reduce total cost of ownership by minimizing downtime and replacing multiple components. Designed for industrial power needs, it aligns with ABB’s robust motor family and accelerates compliant procurement for mining, steel, and other heavy industries.

Exdb flameproof protection combined with an IP66 enclosure delivers safer operation in explosive atmospheres and dusty facilities, reducing regulatory risk and downtime in mining, chemical processing, and oil & gas sites. This is paired with a rugged cast iron frame and 8-pole design to handle demanding loads, improving uptime and lowering maintenance costs through durable construction and reliable bearings (6316/C3). The motor’s IE2 efficiency (Full Load 92.1%, Partial Load 92.3% at 75%, and 91.7% at 50%) translates to meaningful energy savings on long-running conveyors, fans, and hoists, supporting a lower total cost of ownership. Mounting is simplified by a top terminator box and IMB5 IM3001 compatibility, enabling straightforward retrofits or new installations with existing drives and soft starters. At 280 frame size, this unit fits compact spaces without sacrificing performance, making it a practical choice for heavy-duty mining and continuous-duty applications. Its flameproof design is validated for Group I mining environments, while the insulation class ICLF adds an extra layer of protection against electrical stress, helping ensure reliability under high ambient temperatures up to 40 °C and altitudes up to 1000 m. The product is manufactured in Finland, offering consistent quality control and quick access to spares, with a minimum order quantity of one piece to support just-in-time procurement. Compatibility with ABB’s service ecosystem helps streamline installation, commissioning, and ongoing maintenance for industrial operators seeking predictable performance.
