Exdb flameproof protection reduces ignition risk in explosive atmospheres, delivering safer operation and helping you meet ATEX/IECEx compliance in hazardous-area installations. This enables continuous operation in plants where flammable gases may be present, minimizing unplanned downtime and ensuring operator safety. IP55 protection guards against dust and water ingress, extending motor life in harsh environments and reducing maintenance cycles, while IC411 insulation supports reliable performance at elevated ambient temperatures up to 40 °C and altitude up to 1000 m. IE4 efficiency delivers measurable energy savings on continuous-duty loads; at 50 Hz Full Load efficiency is 97.2%, with 60 Hz performance at 96.7%, translating into lower operating costs for conveyors, pumps, and fans. A rugged cast-iron frame with 355 size and 6316 bearings withstands heavy loads, supporting long service life in demanding environments and simplifying serviceability. The 2-pole, S1 continuous duty design ensures predictable uptime, ease of integration with standard ABB drives, and compatibility with existing electrical infrastructure, enabling quick retrofits and fast deployment across multi-site operations.

FAQs
The motor is rated Exdb flameproof for hazardous areas and accommodates gas group IIB with a T4 temperature class. It features IP55 protection, a cast-iron frame (355), and an IK-like robustness suitable for chemical, petrochemical, and mining facilities. It is designed for 40 °C ambient temperatures and up to 1000 m altitude, making it compatible with global installations that require ATEX/IECEx compliance.
IE4 efficiency translates into tangible energy savings on continuous-duty loads. At 50 Hz, Full Load efficiency is 97.2%, with 75% and 50% loads near the same level. At 60 Hz, Full Load efficiency is 96.7%, with 75% and 50% loads at 96.5% and 95.7% respectively. These figures reduce running costs for pumps, fans, and conveyors in hazardous-area environments.
Yes. The motor is rated for S1 continuous duty and features IMB3 IM1001 mounting compatibility, a robust 355 frame in cast iron, and high-grade bearings (6316M/C3). This combination supports long service life under demanding loads, minimizing unscheduled downtime in demanding plants such as refineries, cement mills, and mineral processing lines.
Compliance is supported by Exdb flameproof protection for hazardous locations, IP55 enclosure, IC411 insulation class, and IE4 efficiency. Gas group IIB and Temperature class T4 further confirm suitability for petrochemical and mining environments. The product is designed for safe integration with standard ABB controls and meets industry safety norms.
Robust cast-iron construction, 6316/C3 bearings, and a D-End top terminator box simplify maintenance and reduce service time. The motor’s high IE4 efficiency lowers energy costs, contributing to a favorable ROI over its life cycle. When deployed across multi-site operations, standardized design and compatibility with existing ABB drives streamline procurement, installation, and spare-part management.
