FAQs
ABB 3GJM282220-ADL uses a D connection configuration and operates at 400 V, 50 Hz. The motor is a 4-pole design rated for 75 kW and optimized for direct or star-delta style electrical integration as defined by the D voltage code. This ensures straightforward electrical compatibility with standard industrial drives and switchgear in hazardous areas.
Key specs include 75 kW output, 400 V nominal voltage, 50 Hz frequency, four poles, IP66 enclosure, Exdb flameproof protection, a 280 frame size, and IMB3/IM1001 mounting. The combination supports reliable operation in mining and mineral processing, delivering high torque at start-up while maintaining efficiency and robust protection in challenging environments.
Yes. The motor is Exdb flameproof protected and IP66 sealed, with insulation suitable for demanding mining environments. Its IMB3 mounting and robust cast iron frame are designed for prolonged duty in underground and surface mining, helping meet safety regulations while maintaining high availability under challenging conditions.
The motor carries Exdb explosion protection, IP66 enclosure rating, and insulation class ICLF. It also supports IMB3 IM1001 mounting, IC411 winding insulation, and a 4-pole, 75 kW design for S1 duty. These certifications ensure compliance with mining and hazardous area standards while enabling reliable operation.
The IE3 efficiency rating reduces energy consumption across duty cycles, lowering operating costs. A robust cast iron frame, bearings 6316/C3, and Exdb protection extend service life and reduce maintenance frequency. Although ROI varies with duty cycle and uptime, the combination of protection and efficiency typically yields faster payback in continuous mining operations.
