ABB 3GBC311221-BXG 3-Phase motor - IP55 IC411
Part Number: 3GBC311221-BXG
Quick Summary
ABB 3GBC311221-BXG 3-Phase motor is a rugged, 315-frame squirrel cage motor designed for demanding industrial drives such as pumps, conveyors, and fans. Engineers often face uptime and efficiency challenges when selecting a motor that must tolerate harsh environments, high ambient temperatures, and limited maintenance windows. Key certifications like IP55 for dust and moisture protection, IC411 insulation, and IMB5 IM3001 mounting class underpin long service life in 1000 m altitude and 40 °C ambient conditions. Choosing ABB means predictable performance, compatibility with standard bases, and a robust, maintenance-friendly design that reduces retrofit risk and total cost of ownership.

The 315 frame in cast iron provides stiffness and durability, reducing vibration and extending bearing life in conveyors and pumps. This translates to measurable uptime and lower maintenance costs during peak demand and extended operation. An IP55 enclosure protects against dust ingress and water jets, while IC411 insulation supports reliable performance at 40 °C ambient and up to 1000 m altitude. Together, they enable plants in harsher environments to run longer with fewer unplanned shutdowns. With two poles and a constant-duty S1 rating, the motor delivers steady torque at a fixed speed, simplifying drive design and control integration with standard VFDs or soft starters. The familiar 315 frame also enables straightforward retrofits on existing equipment. The cast iron frame, weight of about 940 kilograms, and base-mounted mounting suit heavy-duty applications while maintaining rugged alignment and long-term stability. The product’s Finland origin and strict manufacturing controls provide traceability and consistent performance across batches. Ready-to-ship with minimal order quantities and ABB's supported service ecosystem helps reduce project risk and total cost of ownership for process industries such as chemical, timber, and metals.

FAQs
This motor uses the standard 315 frame with cast iron construction and base-mounting suitability. Ensure compatibility with existing base plates and feet, confirm the IMB5 IM3001 mounting class, and align with your plant’s vibration and alignment practices. Verify that shaft, coupling, and mounting bolt patterns match your equipment to avoid rework during installation.
The unit is a 3-phase, 2-pole motor designed for S1 continuous duty. It features a voltage code X and operates reliably in ambient temperatures up to 40 °C at altitudes up to 1000 m. The IP55 enclosure provides good protection against dust and water, and the IC411 insulation class supports prolonged operation under typical industrial loads.
Yes. The IP55 enclosure and cast iron 315 frame are well-suited for dusty, humid, and rugged environments. IC411 insulation and the IMB5 IM3001 construction support reliable operation under elevated temperatures and sustained duty, while the 1000 m altitude specification covers many mining and processing scenarios.
Key certifications and classifications include IP55 enclosure protection, IC411 insulation, IMB5 IM3001 mounting class, and the UNSPSC classification 26101100. The Finland origin and associated manufacturing controls provide traceability and alignment with industry reliability expectations.
Expect improved uptime due to rugged cast iron framing, IP55 protection reducing dust and moisture-related faults, and IC411 insulation supporting longer service intervals. A common ROI driver is lower maintenance costs from fewer unplanned shutdowns, matched with easier retrofits on standard 315-frame equipment and predictable performance in continuous-duty applications.
