Exdb flameproof protection reduces ignition risk in Class IIB hazardous areas, enabling safe operation for pumps, mixers, and fans in chemical processing, refining, and mining. This protection supports compliance with ATEX/IECEx requirements and provides peace of mind in mission-critical environments. IE3 efficiency delivers tangible energy savings, with full-load efficiency at 95.8% and near-constant performance across partial loads, lowering running costs for conveyors, pumps, and fans. The IP55 enclosure protects against dust ingress and water jets, ensuring reliable operation in harsh plants and outdoor installations while the cast-iron 355 frame resists vibration and heavy-duty fatigue. A robust bearing set (6316M/C3) extends service life in high-vibration applications such as crushers and material-handling conveyors. Operating at up to 50 °C ambient and up to 1000 m altitude, the motor maintains performance in hot, elevated sites, simplifying installation in global plants. The 2-pole, S1 duty design enables continuous operation with predictable torque, and the D-end top termination box streamlines installation in constrained spaces, improving retrofit viability and panel integration for automation systems.

FAQs
The ABB 3GJA351220-BDDIN is a standard 355 frame, 2-pole, 3-phase squirrel cage motor with IE3 efficiency and Exdb flameproof protection, designed to align with common IEC motor dimensions and control architectures. It supports typical VFD-driven installations and can be integrated into existing drive systems with standard wiring practices, enabling straightforward retrofits in hazardous-area environments.
Key performance specs include IE3 efficiency with full-load up to 95.8%, IP55 protection, a 355 cast-iron frame, and bearing 6316M/C3. The motor operates at ambient temperatures up to 50 °C and up to 1000 m altitude, with a 2-pole, S1 duty rating for continuous operation. Understanding these figures helps size drives, cooling, and electrical protection appropriately.
Yes. The motor features Exdb flameproof protection and gas group IIB suitability, making it appropriate for hazardous-area installations in chemical processing, refining, and oil and gas sectors. It also carries IP55 enclosure protection, supporting dust and water exposure typical in these environments while maintaining reliable operation.
The design targets ATEX/IECEx compliance through Exdb flameproof protection, IP55 ingress protection, and typical IEC motor ratings (IE3 efficiency). The insulation class ICLF and 50 °C ambient tolerance simplify maintenance planning by reducing cooling requirements. Regular inspection of flameproof seals and bearing condition is recommended to sustain compliance and reliability in hazardous zones.
The combination of IE3 efficiency and Exdb protection lowers energy costs and minimizes downtime due to protective features in hazardous areas. Maintenance should focus on bearing health (6316M/C3), inspection of the cast-iron frame for fatigue, and ensuring cable glands and termination box seals remain intact. In high-temperature, high-altitude sites, proactive cooling and periodic performance verification help maximize uptime and return on investment.
