Exdb flameproof protection combined with IP55 enclosure and gas-group IIB rating delivers safe operation in explosive atmospheres, reducing risk and enabling uptime in petrochemical, oil & gas, and mining processes. The business impact is clear: regulatory compliance, minimized risk of ignition sources, and lower incident-related costs across the asset life. The application is ideal for harsh environments such as chemical plants and offshore facilities where flameproof performance and reliability matter. IE4 efficiency at both 50 Hz and 60 Hz meaning lower energy consumption and operating costs over the motor’s life. The robust cast-iron frame (315) with 2-pole design supports long MTBF in heavy-duty conveyors and pumps, while the IMB5 IM3001 mounting alignment ensures straightforward installation and maintenance. Flexible rotation (both sides) and top-entry termination simplify retrofits and new installations in space-constrained facilities. Industry-ready dimensions and compatible bearings enhance long-term reliability for pumps, fans, and mixers in demanding applications.

FAQs
Install the Exdb flameproof motor in accordance with local hazardous-area standards, ensuring IP55-rated enclosure integrity and proper flamepath sealing. Utilize the D-End top termination location for wiring access, and verify rotation direction can be set from both sides. Pair with a compatible 3-phase supply and ABB drive system to maximize energy efficiency and system coordination.
The motor meets IE4 efficiency. At 50 Hz, Full Load is 97.0% with Partial Load at 75% about 97.1% and 50% around 96.8%. At 60 Hz, Full Load is 97.1% with Partial Load around 96.9% at 75% and 96.2% at 50%. Voltage code is D, and it is a 2-pole design optimized for high-efficiency operation in standard 3-phase systems.
Yes. The motor is Exdb flameproof and designed for hazardous locations, paired with IP55 protection and IIB gas-group capability. It provides robust operation in chemical processing, refinery, and related industries where flameproof performance and reliable power are essential, while meeting stringent safety and efficiency requirements.
Key certifications and ratings include Exdb flameproof protection, IP55 enclosure, IE4 efficiency performance, Temperature Class T4, Insulation Class ICLF, and Gas Group IIB. The motor is constructed in a cast-iron frame (315) and is designed for safe operation in hazardous areas with flexible mounting options.
The Exdb flameproof design and IE4 efficiency deliver lower energy costs over the motor’s life. A robust cast-iron frame and precision bearings (6316/C3) support long MTBF, reducing maintenance intervals. Regular inspections of bearings and lubrication, along with periodic checks of termination connections and rotation direction, help sustain reliability in demanding systems such as pumps and conveyors.
