FAQs
For installation, use a solid foundation suitable for a 441 kg net weight motor. The unit features a top terminator box and a 250 frame iron casting, designed for easy alignment with conventional 3-phase drives. Ensure adequate clearance for ventilation, respect the 1000 m altitude limit, and verify ambient temperature does not exceed 40 °C to maintain IC411 insulation performance.
This motor operates with IE Class IE2 at full load, delivering 89.8% efficiency, with 75% partial load at 89.0% and 50% partial load at 88.4%. It uses a voltage code D, is a single-speed S1 duty, and includes Exdb explosion protection with IP66 enclosure. It is built for 3-phase electrical supply and reliable performance under standard industrial conditions.
Yes. The ABB 3GJM254210-ADG is rated Exdb flameproof and IP66 protected, purpose-built for mining and other hazardous environments. With IC411 insulation and a robust cast-iron frame, it supports high duty in dusty, humid, and potentially explosive settings while maintaining safe operation and easier compliance with safety standards.
Key certifications include Exdb explosion protection, IP66 ingress protection, and insulation rated to IC411 with ICLF. The motor is designed to meet demanding industrial and mining regulations, offering reliable operation under elevated ambient temperatures up to 40 °C and at altitudes up to 1000 m, facilitating regulatory compliance and safe field deployment.
The IE2 efficiency class translates to meaningful energy savings across continuous operation and loading variations, improving ROI over the motor’s life. Regular maintenance should focus on bearing condition (6315/C3) and alignment, lubrication for IMB3 IM1001 configurations, and periodic inspection of the Ex-protection system. The robust frame and bearings support longer service intervals and reduced downtime.
