Exd flameproof protection provides inherent safety in explosive atmospheres, reducing the risk of ignition and enabling operation in gas groups IIB environments. This translates to lower insurance costs, higher asset uptime, and easier regulatory compliance for petrochemical facilities. The IP55 enclosure protects against dust ingress and water jets, improving reliability in rugged industrial sites and open-air installations. IE3 efficiency delivers measurable energy savings over life cycle, reducing operating costs and supporting sustainability goals in large-scale automation projects. A 315 frame in cast-iron with 6316/C3 bearings offers robust mechanical integrity, vibration resistance, and extended service intervals, even under continuous S1 duty. The compact two-pole design aligns with standard AB B power interfaces, enabling straightforward drive integration, plug-and-play installation, and reduced commissioning time. Altitude up to 1000 m and ambient 50 °C support reliable performance across diverse geographies, while Exdb protection and gas-group IIB ratings address industry-specific safety requirements for mining, chemical processing, and oil & gas applications. Overall, this motor delivers improved uptime, safer operation, and lower total cost of ownership while aligning with IEC/ATEX expectations for flameproof equipment in critical automation stacks.

FAQs
This motor uses Exd flameproof protection with IP55 enclosure and 315 frame, designed for continuous S1 duty in zones IIB. Install in compliant enclosures, ensure proper cable entry points, and follow ATEX/IECEx guidelines. The 1000 m altitude and 50 °C ambient rating may influence cooling and protection clearances, so plan for adequate ventilation and heat dissipation during commissioning.
IE3 denotes premium efficiency for the motor under full load and partial loads. In practice, this ABB model achieves around 95% efficiency at full load, with high efficiency maintained at partial loads (as indicated by IE Class data). This translates to lower annual energy consumption, reduced heat rejection, and a shorter payback period in energy-intensive applications such as pumps and fans in hazardous environments.
Yes. The unit is specified for S1 continuous duty, with Exdb flameproof protection and gas group IIB ratings. Its cast-iron frame, robust bearings (6316/C3), and IP55 enclosure enable dependable operation in demanding mining, chemical processing, and petrochemical settings while meeting installation standards for explosion-protected equipment.
The motor offers Exd flameproof protection, IP55 ingress protection, Exdb protection, and gas group IIB designation. It complies with industry expectations for explosion-protected equipment, supports safe use in hazardous zones, and aligns with corresponding safety and performance standards in industrial automation projects.
Expect longer service intervals due to robust cast-iron framing and high-quality bearings, reduced risk of ignition in hazardous areas, and lower energy costs from IE3 efficiency. These factors together contribute to lower maintenance downtime, safer operations, and a favorable total cost of ownership over the motor’s service life in demanding industries.
