ABB 3GJM254220-BEG 3-Phase Motor - Exdb Flameproof
Part Number: 3GJM254220-BEG
Quick Summary
ABB 3GJM254220-BEG is a 3-phase squirrel cage motor designed for hazardous environments and mining applications. This drive-ready solution helps keep conveyors, crushers, and pumps running when uptime is critical. Operators often struggle with equipment outages caused by inadequate explosion protection or poor sealing, which this motor mitigates with Exdb flameproof protection and solid IP66 enclosure. The design also leverages robust insulation (ICLF) and industry-standard IE2 and IE3 efficiency profiles to reduce energy waste under VFDs. With Finnish engineering and a rugged cast-iron frame, it delivers predictable performance, long service life, and simpler maintenance, supporting safe, compliant operation in harsh conditions while enabling efficient procurement and lifecycle cost control.

FAQs
This motor uses a top terminator box for simplified wiring and is designed with an 8-pole, IMB5 IM3001 configuration. It supports bidirectional rotation and standard 250 frame housing, enabling straightforward mounting on common bases or adaptors. Verify clearance around the rugged cast iron frame and ensure compliance with Exdb and IP66 requirements before commissioning.
At 50 Hz this motor delivers IE2 efficiency with Full Load around 90.3% and Partial Load around 91.0% for 75% and 50% loads. At 60 Hz the IE Class data shows IE3 efficiency with Full Load about 92.9%, and Partial Loads near 92.8% to 91.4%. These figures support strong energy savings when paired with a VFD.
Yes. The motor carries Exdb explosion protection and an IP66 enclosure, making it well-suited for mining, tunneling, and other hazardous environments. Its IC411 insulation class and flameproof design meet stringent industrial safety standards, while the 8-pole, S1 duty configuration provides reliable continuous operation under heavy load and variable speed conditions.
Key maintenance considerations include bearings rated 6315/C3 with an adjacent 6313/C3 NDE, and a robust Cast Iron frame (Size 250) designed for long service life. Regular checks should focus on bearing wear, ventilation and cooling paths, and adherence to safe operating limits under Exd and IP66 conditions to prevent overheating and downtime.
The motor originates from Finland (FI) and lists Customs Tariff Number 85015230. It falls under WEEE Category 4 for large equipment, ensuring end-of-life handling. Environmental and regulatory data also include altitude suitability (up to 1000 m) and ambient temperature rating (40 °C), supporting compliant, traceable purchasing decisions.
