Feature → Business Impact → Application: The Exdb flameproof protection combined with IP66 sealing minimizes ignition risks in hazardous zones, reducing safety incidents and compliance overhead while enabling continuous mining operations. This translates to lower maintenance costs and higher overall equipment effectiveness (OEE) on belt lines and shaft applications. Feature → Business Impact → Application: The 10-pole, 280 frame with a cast-iron enclosure provides robust mechanical integrity for heavy-duty loads and shock resilience in demanding environments such as mine haulage and processing plants. This supports long service intervals and reduces replacement downtime, ideal for stand-alone drives or plant-wide motor upgrades. Feature → Business Impact → Application: Insulation Class ICLF and IC411 rating ensure stable electrical performance at 40 °C ambient and up to 1,000 m altitude, delivering reliable torque characteristics for continuous S1 operation under variable loading. Feature → Business Impact → Application: Top-entry termination and IMB3 IM1001 mounting compatibility enable faster on-site commissioning and easier retrofits in existing facilities, decreasing installation time and risk of wiring errors. Feature → Business Impact → Application: The motor’s 6316/C3 bearings and cast-iron frame support rugged life-cycle performance, reducing unscheduled maintenance and enabling predictive maintenance programs in underground or above-ground mining operations. Feature → Business Impact → Application: The combination of EX-protection, IP ratings, and robust mechanical design helps ensure compliance with ATEX/IECEx requirements, enhancing safety case documentation for project approvals and asset registers. Feature → Business Impact → Application: The unit’s 85015290 tariff classification and Finland-origin sourcing give procurement teams clearer logistics planning and supply chain resilience for global projects requiring traceability and consistent lead times. Feature → Business Impact → Application: The designation M3JM 280SMC 10 and Product Type alignment support standardized replacement strategy across fleets of flameproof motors, simplifying spares management and training for maintenance personnel.

FAQs
This motor uses a 280 frame with Cast Iron housing and bearing 6316/C3 on IMB3 IM1001 support. Installation is optimized with a Top terminator box and a robust IMB3 mounting footprint, enabling straightforward alignment, secure cable routing, and reliable heat dissipation in hazardous locations.
Yes. It features Exdb flameproof protection and IP66 ingress protection, suitable for hazardous environments. Insulation class ICLF and IC411 provide reliable electrical performance at elevated temperatures, while the 1,000 m altitude rating supports operation in high-altitude sites.
The motor is a 3-phase IE2-equivalent class device with a voltage code D. When pairing with VFDs, ensure the drive is rated for Ex-d use and that motor terminal box access remains sealed. Start-up transients should be managed to preserve bearing life and limit torque shocks on heavy loads.
Absolutely. With Exdb flameproof protection, IP66 protection, 10 poles for robust starting torque, and a cast-iron frame, it is well-suited for mining, cement, and other heavy industries where hazardous zones and demanding duty cycles (S1) are common.
Implement a bearing inspection schedule for 6316/C3 bearings, monitor vibration and temperature, and perform lubrication per ABB guidance for IMB3 IM1001 assemblies. The rugged frame and protective features reduce unplanned outages, delivering a favorable total cost of ownership over long asset lifecycles.
