FAQs

The M3BC 280SMB 2 uses a 280 frame with IMB3 IM1001 mounting, designed for straightforward foot or flange mounting on standard base plates. Its Cast Iron frame provides rigidity, while the 0 pallet (lift) packaging level indicates suitability for controlled installation in typical industrial settings. This combination minimizes integration time and aligns with common drive systems in automation lines.
Key specifications include IP55 enclosure protection, IC411 insulation class, and a 2-pole high arrangement suited for continuous S1 duty. Ambient temperature is rated at 40 °C with operation up to 1000 m altitude. The motor uses a defined voltage code X and a mass of 665 kg net, which informs wiring, enclosure sizing, and cooling considerations during installation.
Yes. The product is specified for S1 continuous duty, providing reliable torque and thermal characteristics suitable for pumps, fans, and conveyors. The IP55 protection and cast iron construction support sustained operation in dusty or semi-exposed environments, while IMB3 IM1001 mounting supports stable, long-life alignment in demanding automation setups.
This ABB motor originates from Finland (FI) and carries a customs tariff number 85015381. It is categorized under UNSPSC 26101100 and supports standard industrial procurement practices. The combination of IP55 and IC411 insulation serves as primary regulatory and performance indicators for compliance and reliability in global projects.
The cast iron frame and robust IMB3 mounting reduce vibration and misalignment, contributing to longer bearing life and lower maintenance costs. The IP55/IC411 protection minimizes protective measures and field servicing needs, while the overall heavy mass aids stability and consistent performance. These factors collectively shorten downtime, extend service intervals, and support a favorable return on investment in automation deployments.
