Flameproof Exd and Exdb protection safeguard personnel and equipment in hazardous locations, reducing project risk and potential shutdowns in mining and related industries. This protective standard directly translates to safer installations and fewer costly retrofits when expanding operations in explosion-prone areas. IP66 ingress protection paired with IC411 insulation enhances durability in dusty, wet environments, enabling continuous operation with minimal maintenance in harsh industrial settings. IE2 efficiency with Full Load 93.8% and Partial Loads around 93% delivers measurable operating cost reductions over long duty cycles, supporting energy-management goals and green-compliance initiatives for large-scale mining facilities. The cast-iron frame (250) and heavy-duty bearings (6315M/C3, 6313M/C3) provide rugged reliability under continuous S1 duty while maintaining alignment and reducing vibration-induced wear. A top termination box simplifies electrical connections and serviceability, improving installation speed and field maintenance in remote sites. With a 1000 m altitude rating and 40 °C ambient allowance, the unit remains robust in elevated operations, contributing to lower lifecycle costs and easier compliance with strict industrial standards. Support for precise 2-pole operation and a defined IM class (IMB5 IM3001) ensures predictable performance in control systems and automation architectures commonly used in mining conveyors and processing lines.

FAQs
This model uses a top termination box and a 250 frame with a cast-iron body, designed for straightforward mounting on standard bases. Plan for 514 kg net weight (524 kg gross) and a 1000 m altitude rating. Ensure electrical connections meet Exd/Exdb protection requirements and align with the IC411 insulation class. Provide adequate ventilation and secure mounting to minimize vibration in mining conveyors and processing lines.
IE2 efficiency is rated with Full Load at 93.8% and Partial Load around 93.2–93.9%, translating into lower energy consumption during continuous S1 duty. In mining and heavy industry, savings compound over long runtimes and high utilization, contributing to reduced kilowatt-hour expenses and improved total cost of ownership when paired with variable-speed or fixed-speed drive systems.
Yes. The motor features Exd flameproof protection and Exdb explosion protection, IP66 enclosure, and IC411 insulation, all aligned with hazardous-location standards. Its 2-pole design and S1 duty are intended for continuous operation under demanding conditions found in mining, mineral processing, and other challenging environments, while the rugged cast-iron frame supports heavy equipment interfaces.
The unit carries Exd flameproof and Exdb explosion protection, IP66 ingress protection, and IC411 insulation. It adheres to IE2 efficiency targets and is designed for high-altitude operation up to 1000 m with ambient up to 40 °C. Additional compliance include WEEE categorization and standard mining/machinery classifications, providing regulatory confidence for hazardous-area installations.
The combination of Exd/Exdb protection, IP66 enclosure, and IE2 efficiency reduces downtime and energy costs in continuous mining operations. The top-termination and robust bearings (6315M/C3, 6313M/C3) simplify maintenance scheduling, while the cast-iron frame supports long service life under heavy loads. ROI improves with lower energy bills, reduced risk of hazardous-area incidents, and easier field service in remote sites.
