Exdb flameproof protection paired with an IP66 enclosure ensures safe operation in hazardous environments, reducing compliance risk and downtime in mining and chemical processing. The business impact is clear: safer installations and fewer incident-driven outages, which translates to higher uptime and lower total cost of ownership for critical drives. This motor’s 8-pole, 250 frame and cast-iron construction deliver rugged durability, supporting heavy-load applications such as conveyors and crushers in harsh field conditions. The result is extended service life, lower maintenance intervals, and predictable performance in remote sites where spare parts and service access can be limited. IE2 efficiency at full load (89.8%) delivers measurable energy savings in continuous operation, directly improving operating margins for processing and materials handling facilities. A top-termination box and aligned IM class (IMB3 IM1001) simplify installation and wiring, reducing commissioning time and human error during start-up. Designed for 1000 m altitude and 40 °C ambient, this motor minimizes derating and keeps performance within spec for high-altitude mines and plants. Overall, the combination of Exd protection, robust mechanicals, and energy-efficient operation supports compliance, reliability, and long-term cost containment in industrial environments.

FAQs
This motor is designed with Exdb flameproof protection and an IP66 enclosure, making it suitable for explosive zones. Installers should ensure proper dust and moisture protection, confirm cable entry sealing, and follow local electrical codes. The top-termination box simplifies wiring and allows straightforward field connections, reducing commissioning time and potential mistakes during installation.
Key specs include 8 poles, frame size 250, IE2 efficiency with full-load efficiency at 89.8%, voltage code E, and Exdb protection. These factors translate to reliable torque, efficient operation under continuous load, and compliance with energy targets in mining and heavy industry. IC411 insulation supports enduring thermal performance, while IP66 ensures robust protection against ingress in tough environments.
Yes. With Exdb flameproof protection, IP66 enclosure, cast-iron frame, and robust bearings (6315/C3), the motor is built for continuous duty in challenging mining applications. Its 1000 m altitude tolerance and 40 °C ambient rating support remote installations, while IE2 efficiency minimizes running costs, making it an economical choice for long-wall and conveyor drives.
The motor features Exdb flameproof protection, IP66 ingress protection, and IC411 insulation class, all essential for safe operation in hazardous environments. These certifications reduce risk, help meet regulatory requirements for mine and chemical processing installations, and support maintenance planning by providing clear durability and operating limits for long-term reliability.
ROI benefits come from improved uptime, lower maintenance intervals due to durable cast-iron construction, and energy savings from IE2 efficiency. For maintenance, prioritize bearing inspections (6315/C3) and periodic checks of the top-termination box wiring. Its rugged design minimizes unscheduled downtime, delivering steady productivity gains in high-demand production lines.
