FAQs
When installing the ABB 3GJM251210-ASL, ensure the IMB3/IM1001 mounting is followed and the terminator box is positioned as specified (top). Use a Y connection on 400 V, 50 Hz systems and verify the 2-pole, 3-phase supply can handle start-up torque. Maintain IP66 protection and Exdb flameproof integrity by sealing the enclosure and avoiding incompatible accessories in hazardous zones.
The motor is rated IE3 at 50 Hz with Full Load efficiency around 94.3%. At 75% and 50% loads, efficiency remains high (≈94.1% and ≈93.5% respectively). For 60 Hz operation, IE3 efficiency is slightly reduced (Full Load ≈93.6%, 75% ≈93.1%, 50% ≈91.7%). This supports predictable energy savings across varying duty cycles in mining applications.
Yes. The 55 kW, 2-pole, frame 250 motor with Exdb flameproof protection and IP66 enclosure is specifically designed for mining equipment such as conveyors and crushers operating in hazardous areas. Its robust mechanical design and high starting torque suitability make it a strong candidate for demanding conveyor drives and crushing applications.
This motor features Exdb flameproof protection and IP66 enclosure for hazardous environments, along with IE3 premium efficiency. It also supports IMB3/IM1001 mounting and IC411 insulation class, contributing to regulatory compliance in mining and industrial settings. These certifications help customers meet safety and energy standards without compromising performance.
Expect lower maintenance downtime due to rugged cast-iron frame, durable bearings (6315M/C3 and 6313M/C3), and a simple Y-configured 400 V, 50 Hz drive. The IE3 efficiency reduces energy costs in continuous operation, improving total cost of ownership. Reliable protection (IP66, Exdb) means fewer replacements and extended service life in harsh mining environments.
