Explosion protection and rugged enclosure deliver safer operation in explosion-prone zones, with Exdb flameproof protection and IP66 ingress protection reducing ignition risk and dust ingress. This directly lowers maintenance interruptions and extends asset life in harsh environments. The IE2 efficiency rating, supported by Full Load 92.4% and Partial Load values up to 92.8%, translates to meaningful energy cost reductions across continuous duty cycles in mining and processing lines. A cast iron frame (280) with bearings 6316/C3 and an IMB5 mounting class delivers high torque and long bearing life, improving uptime and reducing spare parts spend. The 8-pole design enables suitable torque curves for conveyors and crushers, while the top terminal box and 0 pallet packaging support straightforward installation and safer connector access. Compatibility with standard industrial drives and a 40 °C ambient tolerance simplifies commissioning and ensures reliable starts under demanding duty.

FAQs
This motor uses IMB5 mounting with a 280 frame and top-mounted termination box, designed for both rotation directions. Plan for flameproof electrical connections and a compliant explosion-protected starter. Ensure proper alignment, secure mounting, and correct cable ingress protection to preserve the Exdb rating. Respect 40 °C ambient limits and up to 1000 m altitude during installation and commissioning.
The motor meets IE2 efficiency. Full-load efficiency is 92.4%. At partial loads, efficiency remains high: about 92.8% at 75% load and 92.7% at 50% load. With an 8-pole design and star-delta compatibility, operators can optimize drive settings to balance energy use with torque requirements, achieving meaningful energy cost savings in continuous operations.
Yes. The Exdb flameproof protection and IP66 enclosure enable safe operation in explosion-risk zones typical of mining and processing plants. The 8-pole, 280-frame, cast-iron construction supports high torque for conveyors and crushers, while the IC411 insulation and IE2 efficiency help maintain reliable performance under harsh ambient conditions.
Key certifications include Exdb flameproof protection, IP66 ingress protection, and IC411 insulation. It also carries IE2 efficiency data and a robust mining-oriented product designation. Compliance with WEEE category 4 and the frame and bearing specifications support long service life, helping meet stringent industry and environmental regulations in heavy industries.
The combination of explosion protection, rugged mechanical design, and high IE2 efficiency reduces downtime and energy costs in hazardous environments. Cast-iron construction, durable bearings, and top-end mounting enable longer intervals between maintenance, lowering total cost of ownership. Heavier upfront investment is offset by lower spare parts usage and fewer unscheduled outages in mining and processing lines.
