Feature → Business Impact → Application: The M3BC 280SMC 2 uses a 2-pole, 3‑phase squirrel cage design to deliver reliable torque in continuous duty, improving line uptime and reducing unplanned maintenance for conveyors and pumps in manufacturing environments. This translates to measurable productivity gains and lower energy waste in high-load processes, while the cast iron frame resists deformation under vibration and heat. Application-wise, it fits standard IEC mounting schemas and IMB3 IM1001 mounting classes, simplifying retrofits and new installations on existing OEM lines. Feature → Business Impact → Application: IP55 protection guards against dust and water ingress in dusty plants or outdoor installations, reducing motor failures and service calls in harsh production floors. This enables longer service intervals and predictable maintenance budgets for material handling and process automation. Feature → Business Impact → Application: Insulation Class ICLF supports higher ambient temperatures and thermal self-protection, increasing reliability for processes near the upper temperature envelope. In practice, this means fewer thermal shutdowns on fans, pumps, or mixers operating at elevated ambient temperatures in the 40 °C range. Feature → Business Impact → Application: IMB3 IM1001 mounting compatibility provides flexible installation in refurbished lines and OEM equipment, allowing straightforward swapping of legacy motors without extensive rework. This reduces installation time, accelerates project timelines, and lowers commissioning risk in batch or continuous production environments. Feature → Business Impact → Application: The 280 frame with a 725 kg product net weight signals heavy-duty construction designed for demanding applications, supporting stable operation on long conveyors and hoisting systems while maintaining alignment and balance during high-torque starts.

FAQs
The M3BC 280SMC 2 uses a conventional 280 frame with IMB3 IM1001 compatibility, supporting standard IEC mounting patterns. This facilitates retrofits and new installations on existing conveyors, pumps, and process equipment without extensive rework. When planning a swap, verify mounting flange alignment, shaft dimensions, and available service clearance to ensure a smooth integration.
Key specs include a 2-pole design, 3‑phase operation, Cast Iron frame, IP55 protection, IC411 enclosure, Insulation Class ICLF, and a 725 kg net weight with 745 kg gross. The motor is rated for S1 duty in continuous operation and is not a two-speed motor, making it predictable for constant-speed drives in standard industrial processes.
Yes, it is designed for up to 1000 m altitude and 40 °C ambient temperature, making it suitable for many mid- to high-altitude plants and warm production floors. The combination of IP55, IC411, and ICLF insulation supports reliable performance under these conditions, though extreme environments may require verifications for derating and cooling strategies.
The motor features IP55 protection, IC411 enclosure, and Insulation Class ICLF, aligning with typical European and international protection and insulation standards for industrial motors. These certifications support safe operation in dusty or damp environments and improve compliance for equipment installed in regulated facilities and OEM builds.
With a robust cast-iron frame, IP55 protection, and a heavy-duty 2-pole design, maintenance intervals can be extended due to reduced ingress damage and lower thermal stress. ROI improves through higher uptime, predictable maintenance costs, and compatibility with existing mounting and spare parts, especially on conveyors and pumps, where downtimes directly impact production throughput.
