Exdb flameproof protection provides inherent explosion protection for hazardous areas, reducing ignition risk and compliance costs by design. This enables reliable operation in zone 1/2 environments with less need for additional protective enclosures or costly mitigations, making it ideal for underground conveyors and ore handling in mining operations. IE3 premium efficiency reduces energy consumption across full and partial load conditions, delivering measurable operating savings and cooler equipment temperatures over the motor’s life. IP66 enclosure and IC411 insulation ensure robust dust, water, and heat resistance, minimizing maintenance downtime in dusty processing plants and harsh outdoor sites. The 8-pole, frame 280, cast-iron construction supports IMB5/IM3001 mounting and top terminator box placement, simplifying retrofits and new installations while enabling consistent service intervals. A Y-configuration connection with 400 V supply and 50 Hz frequency eases integration with existing plant networks, reducing wiring complexity and commissioning time. All these features translate to lower total cost of ownership, better compliance, and dependable performance in demanding mining applications.

FAQs
Use the Y (star) connection configuration for 400 V operation per the electrical data. Ensure the terminal box is accessible (top location recommended) and confirm the 50 Hz supply aligns with full-load IE3 efficiency. Verify pole count (8) and frame size (280) during installation to match IMB5/IM3001 mounting.
The motor features Exdb flameproof protection and IP66 enclosure, designed to resist hazardous atmospheres and ingress of dust and water. This combination supports compliance with mining safety standards and reduces the need for additional protective housings in underground or surface mining environments.
Yes. It is rated for ambient temperatures up to 40 C and elevations up to 1000 m, making it suitable for both underground and surface mining operations where heat and altitude can impact performance. Insulation class ICLF further supports reliable operation under these conditions.
The motor uses a cast-iron frame size 280 with 8 poles and bearings 6316/C3. It supports IMB5/IM3001 mounting and features a top-position terminator box, simplifying installation and future maintenance in tight or constrained spaces commonly found in mining facilities.
IE3 efficiency offers higher full-load performance, with measured IE3 outputs around 92.2% at 50 Hz and 92.1–92.4% under partial loads depending on speed and load. This translates to meaningful energy savings, reduced heat generation, and lower operating costs over the motor’s lifecycle in mining and processing applications.
