Flameproof protection with Exdb means the motor operates safely in hazardous zones, reducing risk and downtime for mining equipment and processing plants. This protection translates to regulatory compliance and peace of mind for maintenance teams, especially in underground installations where fire and explosion hazards are present. The combination of IP66 ingress protection and ICLF insulation contributes to reliable performance under challenging ambient conditions, such as dust, water splash, and extreme temperatures, which lowers the cost of ownership over time. The IE2 efficiency rating delivers meaningful energy savings in continuous-duty S1 applications, with full-load efficiency around 92.2% and high partial-load performance, cutting operating costs across shifts. A rugged 250 frame, cast-iron construction, and bearings (6315/C3 with 6313/C3 NDE) provide longevity and predictable torque for heavy loads. The top terminator box simplifies wiring in tight spaces and supports fast maintenance or motor swaps, improving uptime. Overall, this motor aligns with industry best practices for mining and other hazardous-area operations, offering reliable performance, ease of installation, and a strong total cost of ownership profile.

FAQs
The motor uses a 250 frame with a top terminator box for easy wiring in tight spaces. It features a robust cast-iron frame and IMB5 IM3001 mounting class, designed to fit standard 250 mm footprints. Top-entry wiring and a 6-pole design provide reliable starts, enabling straightforward installation in hazardous areas and ensuring quick maintenance access when needed.
This motor operates with IE2 efficiency, showing Full Load (100%) around 92.2%, Partial Load (75%) about 92.5%, and Partial Load (50%) near 91.8%. It is a 6-pole design with a voltage code of S and Exdb flameproof protection, delivering consistent torque and performance across search-and-plant duty cycles while maintaining compliance with IP66 protection and IC411 insulation.
Yes. The 3GJM253210-BSG is built for hazardous environments with Exdb flameproof protection and explosion-protected capabilities. It is designed for Group I mining applications, offering reliable operation under 40 °C ambient and up to 1000 m altitude, and supports safe operation in confined, dust-laden underground spaces where explosion hazards are present.
Key certifications include IP66 ingress protection, Exdb flameproof protection, and ICFL insulation. It is rated for IE2 efficiency in 50 Hz operation, with a TOP terminator box for easier wiring. Additional classifications include 6 poles, S1 duty, and a country of origin of Finland, with Customs Tariff Number 85015230 and UNSPSC 26101100 referenced for procurement compliance.
The rugged cast-iron frame, high-quality bearings (6315/C3 and 6313/C3 NDE), and top-entry design minimize maintenance complexity and downtime. IE2 efficiency reduces energy costs in continuous operation, while the Exdb flameproof design lowers risk-related downtime in hazardous zones. The motor’s standard 1 piece MOQ and lack of required customization further reduce procurement time and total cost of ownership.
