FAQs
The ABB 3GJM252220-BSG is designed for easy integration with standard ABB control gear, including starters and drive systems. With a 250 frame size, a robust cast-iron body, and bearing arrangement 6315/C3, it fits common mounting footprints and simplifies retrofits. Compatibility with existing IEC components minimizes cabinet modifications and speeds up commissioning.
Key factors include IP66 protection, Exdb flameproof certification, IE2 efficiency, IC411 insulation, four-pole design, and a 250 frame. Additional influence comes from ambient temperature up to 40 °C, altitude up to 1000 m, and a 4-pole, S1 duty configuration. These specs drive reliability, energy efficiency, and safe operation in hazardous environments.
Yes. The Exdb flameproof protection, IP66 enclosure, and flameproof design qualify it for mining use. The 4-pole, single-speed S1 duty, and robust cast-iron frame optimize durability under continuous operation and heavy load profiles typical of conveyors and material-handling equipment in rugged mining sites.
The motor features Exdb explosion protection and IP66 ingress protection, along with IC411 insulation and IE2 efficiency. Its duty class is S1, and the product designation includes flameproof and mining-grade attributes. It also carries a 4-pole design and robust mechanicals suitable for demanding environments, aligning with typical mining and industrial safety requirements.
The 6315/C3 bearings, cast iron frame, and durable 250 frame enable long service life with fewer bearing replacements and reduced downtime. Exdb and IP66 protection lower maintenance complexity in hazardous locations. Combined with IE2 efficiency and reliable uptime, this motor can lower total cost of ownership for large-scale, continuous-process installations.
