Exdb flameproof protection paired with IP66 ingress protection reduces ignition risk and dust entry in hazardous environments, translating to fewer unplanned shutdowns and improved safety compliance in mining and similar settings. This directly lowers maintenance costs and downtime while ensuring steady performance under demanding conditions. The IE2 efficiency rating delivers tangible energy savings across full and partial load scenarios; the documented full-load efficiency around 94.2% and partial-load figures near 94.3% translate to measurable operating cost reductions over the motor’s life. A rugged cast-iron frame (size 250) and a robust 2-pole design provide durability in harsh environments, with easy mounting and straightforward integration into existing ABB drive ecosystems. Top termination for wiring and Exdb protection further simplify installation in hazardous zones, reduce wiring errors, and support reliable long-term operation. The motor’s operating envelope includes 1000 m altitude and 40°C ambient temperature, ensuring steady performance where harsh conditions and space constraints prevail. Compatibility with standard ABB control gear and a proven IM class (IMB3 IM1001) support quick commissioning and maintenance, delivering lower total cost of ownership for mining and heavy industry applications.

FAQs
Mounting requires a 250 frame, top-termination box, and alignment with standard mounting patterns for a 2-pole motor. Use suitable gland connections for Exd environments, verify bearing specs (6315M/C3) and NDE (6313M/C3), and ensure the motor is wired to a compatible ABB drive system. Plan for IP66 sealing and cable entry protection in hazardous zones.
This motor is rated IE2. Typical full-load efficiency is around 94.2%, with partial-load (75%) around 94.3% and at 50% load about 93.7%. These figures support meaningful energy savings across operating profiles common in mining and continuous-process applications, contributing to lower energy costs and improved sustainability metrics.
Yes. The ABB 3GJM251230-ADG features Exdb flameproof protection, IP66 enclosure, and IC411 insulation with an IC Class framework, making it appropriate for mining and other hazardous environments. The motor is designed for continuous S1 duty and can operate safely under demanding ambient conditions up to 40°C and 1000 m altitude.
Key certifications include Exdb flameproof protection, IP66 ingress protection, and IC411 insulation class, with IE2 efficiency. It is also designed with cast-iron frame, 250 size, 2-pole configuration, and a top-termination box. Additional compliance aspects include a Finnish origin, Customs Tariff 85015381, and WEEE category 4 classification for large equipment.
Net weight is approximately 524 kg with a gross weight of about 534 kg, reflecting a robust cast-iron construction. When shipping, ensure proper lifting equipment for a 250-frame motor and plan for top-termination wiring access. Handling should follow standard safety procedures for heavy, hazardous-area electrical equipment to maintain integrity of Exdb protections during installation and service.
