Exdb flameproof protection paired with IE4 energy efficiency delivers safer operation in hazardous zones while reducing energy consumption and operating costs. The IP55 ingress protection and cast-iron frame enhance durability in dusty, humid, or wet plant environments, enabling longer intervals between maintenance and fewer unplanned outages. The 4-pole design supports steady torque and reliable speed control under S1 duty, making it well-suited for conveyors, pumps, and compressors in process industries. ICFL insulation and a T4 temperature rating ensure thermal reliability at ambient temperatures up to 40 C and altitudes up to 1000 m, safeguarding long-term performance and warranty compliance. The motor’s robust bearings (6319/C3 bearing) and IMB3 IM1001 class support extended running life in demanding installations, while the Exdb protection and Gas Group IIB classification simplify regulatory compliance for hazardous-area applications. This model also integrates smoothly with standard drives and control schemes, minimizing integration risk and enabling quick project scaling for offshore, chemical, and petrochemical facilities.

FAQs
Yes. The motor is a 4-pole design with standard cast-iron frame dimensions, aligning with common IEC mounting patterns. It can replace similar 4-pole industrial motors in conveyors, pumps, and fans, provided the Exdb flameproof requirement and IP55 protection are maintained in the installation and the control gear is approved for hazardous areas.
Key specs include IE4 efficiency, 4-pole configuration, voltage code D, and a Temperature Class of T4. It offers Exdb flameproof protection and IP55 ingress protection, suitable for hazardous environments up to 40 C ambient and 1000 m altitude, with a 3-phase supply compatible with standard ABB drives.
Yes, it is rated Exdb flameproof with IP55 protection, and it is suitable for hazardous-area applications such as chemical and oil & gas processing. Gas Group IIB classification and Temperature Class T4 support regulatory compliance, while the ICFL insulation and IE4 efficiency reinforce safe, energy-efficient operation.
The motor uses a 315 frame with cast-iron construction and standard mounting footprints. It is designed for straightforward integration with ABB drives and control systems, minimizing integration risk. Dimensions (1475 mm length, 929 mm height, 654 mm width) support direct mounting in spaces typical of heavy-duty process equipment.
With IE4 efficiency, robust bearings, and a durable cast-iron frame, the motor reduces energy consumption and maintenance frequency in demanding environments. The Exdb flameproof rating and IP55 protection lower the risk of environmental faults, contributing to higher uptime and a favorable total cost of ownership in hazardous-area applications.
