Exdb flameproof protection with IP66 ingress rating provides safe operation in hazardous zones, reducing ignition risk and downtime while meeting mining and chemical processing safety standards. This design supports faster, safer maintenance cycles and easier regulatory audits, especially in underground or surface plants where ignition sources must be contained. The motor’s energy efficiency is demonstrated by IE2 performance at 50 Hz and IE3 at 60 Hz, driving lower operating costs and helping meet energy-use targets on site. Built with a cast-iron 250 frame and bearings 6315/C3 and 6313/C3, it delivers high torque and durable service in continuous duty (S1) operations, translating to fewer repairs and longer intervals between overhauls. A top terminator box location simplifies wiring during installation and service, while a robust IMB3 IM1001 mounting class supports flexible alignment in constrained spaces. The 8-pole design delivers reliable speed control and reduced vibration, beneficial for sensitive hydraulic and conveyor systems. With a 40 °C ambient rating and 1000 m altitude capability, the motor maintains performance in diverse site conditions, reinforcing uptime and process reliability in mining, cement, and chemical applications.

FAQs
This motor is designed for Exdb flameproof environments with IP66 protection, making it suitable for mining and other hazardous zones. It features a top terminator box for straightforward field wiring, a cast iron 250 frame, and bearings 6315/C3 and 6313/C3 to support reliable mounting and long service life. Ensure enclosure and panel ratings match local ATEX/IECEx requirements and confirm mounting fits IMB3 IM1001 standards.
At 50 Hz the unit aligns with IE2 efficiency, delivering Full Load efficiency around 90.3% in standard duty, while at 60 Hz it shifts toward IE3 efficiency, with Full Load efficiency near 92.9%. The motor uses an 8-pole configuration to balance speed and torque, suited for S1 continuous duty in high-load applications such as conveyors and pumps in mining and processing plants.
Yes. The ABB 3GJM254220-AEG features Exdb flameproof protection and an IP66 rating, designed for hazardous locations where ignition sources must be contained. It also carries insulation and design features (ICFL and 8-pole IMB3 mounting) that support long-term reliability in challenging environments, aligning with safety standards in mining, cement, and chemical processing.
Key certifications and standards include Exdb flameproof protection and IP66 ingress protection, ICFL insulation classification, and IE2/IE3 efficiency ratings for 50/60 Hz. The motor is designed for IMB3 IM1001 mounting, has a robust cast-iron frame, and is suitable for continuous operation in environments with ambient temperatures up to 40 °C and elevations up to 1000 meters.
The heavy-duty cast-iron frame and precision bearings 6315/C3 and 6313/C3 deliver strong vibration resistance and long bearing life, reducing overhaul frequency. Top-terminal box simplifies maintenance wiring, and the Exdb/IP66 construction minimizes risk of damage from dust and moisture. The result is improved uptime, lower maintenance costs, and predictable total cost of ownership in remote or harsh industrial sites.
