FAQs
ABB 3GJM281220-AEG is a 2-pole, 3-phase IE2 motor with Exdb flameproof protection and IP66 enclosure. It fits a standard 280 frame with a top termination box, suitable for hazardous locations. Ensure compliance with local mining codes, verify gasket integrity, and connect via shielded cables. Install by a qualified technician to maintain flameproof integrity.
Key specs include IE2 efficiency with Full Load at 94.6%, partial-load performance around 94.7% at 75% and 93.8% at 50%. The motor is 2-pole, frame 280, with a cast iron frame, bearing 6316/C3, and IC411 insulation. Duty is S1, voltage code E, Exdb protection, and IP66 rating, enabling reliable continuous operation in harsh settings.
Yes. With Exdb flameproof protection and Group I mining suitability, IP66 enclosure, and robust construction, the 3GJM281220-AEG is well-suited for underground and surface mining applications. Ensure installation complies with local safety standards and that the drive system matches the 2-pole, S1 duty requirements of the mining process.
Energy efficiency from IE2 reduces running costs on continuous operations. The rugged cast iron frame and IP66 enclosure lower wear and maintenance needs, while a durable bearing (6316/C3) extends service life in dusty environments. Combined, these factors reduce downtime, extend intervals between servicing, and improve return on investment for mining and heavy industry fleets.
Key certifications include Exdb flameproof protection for hazardous zones, IP66 enclosure, IE2 energy efficiency, and IC411 insulation. It operates at up to 1000 m altitude and 40 °C ambient, with UNSPSC 26101100 classification. Confirm local regulatory compliance and ensure installation by qualified personnel to maintain certification status.
