ABB 3GBJ356825-ADG 3-Phase squirrel cage motor - IP55
Part Number: 3GBJ356825-ADG
Quick Summary
ABB 3GBJ356825-ADG is a 3-phase squirrel cage motor designed for demanding industrial drive applications such as conveyors, pumps, and fans. Plant engineers often face unreliability, overheating, and escalating maintenance costs when scaling up power for continuous-duty equipment. This model delivers IP55 enclosure protection, insulation class ICLF, and IMB3 mounting to boost uptime and ease installation in tough plants. Originating in Finland, the cast‑iron frame motor combines mass and rigidity with a proven bearing arrangement for long service life, reducing vibration and noise. For procurement and operations teams, this means lower replacement cycles, predictable performance, and better overall return on investment in automation projects.

Feature: Cast iron frame and 355 frame size provide exceptional rigidity under heavy loads. This reduces vibration and bearing wear, extending motor life and simplifying alignment during maintenance. Application: Suitable for high-load conveyors, pumps, crushers, and other heavy-duty drives in steel mills, mining, and process plants. Feature: IP55 enclosure and insulation class ICLF. Business Impact: Protects against dust and moisture while tolerating ambient temperatures up to 40°C at 1000 m, reducing unscheduled downtime and improving reliability. Application: Harsh manufacturing floors, packaging lines, and processing plants where environmental exposure is a concern. Feature: 12-pole design with S1 duty. Business Impact: Delivers high starting torque and stable speed for continuous operation, minimizing speed fluctuations and electrical stress on drive systems. Application: Conveyors, pumps, and fans with constant-speed requirements in heavy industrial settings. Feature: IMB3 mounting and premium bearings (6322/C3 and 6316M/C3 VL0241). Business Impact: Enables robust, vibration-resistant installation with long bearing life and lower maintenance needs. Application: Fixed installations in skids and bases across manufacturing and processing lines. Feature: High-inertia rotor and cast-iron construction for reliability. Business Impact: Improves load response, reduces resonance, and supports predictable performance under peak loads. Application: Continuous-process lines in metalworking, mining, and heavy equipment operations.

FAQs
Install using the IMB3 mounting class with a rigid baseplate and appropriate vibration isolation. Ensure proper shaft alignment, hoisting equipment for the heavy 2690 kg net weight, and secure electrical connections per voltage code D. Verify bearing access (6322/C3 and 6316M/C3) during setup and follow ABB installation guidelines for 1000 m altitude and 40°C ambient limits.
This is a 3-phase squirrel cage motor with 12 poles designed for S1 continuous duty. Key specs include IP55 enclosure, insulation class ICLF, voltage code D, cast iron frame 355, and a heavy-duty bearing arrangement (6322/C3 and 6316M/C3). It’s built for steady operation and reliable performance in demanding environments.
Yes. The motor is rated for ambient temperatures up to 40°C and operation at elevations up to 1000 meters, with IP55 protection for dust and moisture. The ICLF insulation and IMB3 mounting further support reliable performance in challenging plant conditions typical of metal, mining, and processing facilities.
Best suited for heavy-duty, continuous-process applications such as conveyors, pumps, and fans in manufacturing, mining, and processing plants. The 355 cast iron frame, IP55 enclosure, and IMB3 mounting provide rugged reliability, while 12-pole design ensures stable speeds under load and efficient integration with ABB control systems.
The motor’s robust frame, high-inertia rotor, and premium bearings reduce vibration, wear, and unplanned downtime. Continuous operation (S1) with IMB3 mounting simplifies service planning, while compatibility with ABB drives supports energy optimization and predictable performance, delivering lower maintenance costs and improved total cost of ownership over its service life.
