Feature → Business Impact → Application: Exd flameproof protection and an IP55 enclosure deliver enhanced safety and regulatory compliance in hazardous areas, reducing risk and minimizing costly shutdowns during maintenance. This translates to higher plant availability for chemical, petrochemical, and mining operations, where explosion protection is mandatory. Feature → Business Impact → Application: IE3 energy efficiency (Full Load 95.2%, at 75% load 95.0%, at 50% load 94.2%) lowers energy consumption and operating costs across continuous processes, supporting green initiatives and long-term ROI for pumping, fans, and compressors in oil & gas facilities. Feature → Business Impact → Application: Cast iron frame (280) with 6316/C3 bearings and IMB3 IM1001 class design offers superior durability under shock loads and high-temperature operation, delivering extended service life in demanding environments such as cement, mining, and metalworking. Feature → Business Impact → Application: 2-pole, S1 duty, and Exdb protection simplify installation and integration with existing electrical infrastructure, enabling straightforward commissioning in new builds or retrofits. Feature → Business Impact → Application: Terminator box located at D-End top and a robust mechanical package improve field serviceability, allowing easier wiring, safer maintenance, and lower downtime during motor swaps. These features collectively support compliance with international standards while driving measurable reductions in total cost of ownership for hazardous-area applications.

FAQs
Plan for an explosion-protected installation by following ATEX/IECEx guidelines and the device’s Exd rating. Use properly rated conduit entries and glands, ensure the terminator box is located as specified (D-End top), and verify enclosure seals and cable routing to preserve IP55 integrity. Confirm alignment, wiring practices, and torque specs during commissioning to sustain safety and uptime in hazardous zones.
The motor delivers IE3 efficiency with full-load around 95.2%, and at partial loads (75% and 50%) around 95.0% and 94.2% respectively. In practice, you’ll see lower energy consumption for continuous processes, translating to reduced operating costs and improved return on investment in pumps, fans, and conveyors operating in warmer environments.
Yes, the motor supports continuous S1 duty, making it suitable for constant operation in demanding environments. Exdb indicates explosion protection for gas atmospheres, and Gas Group IIB specifies tolerance for certain hydrocarbon gas mixtures. Together, they ensure safe operation in chemical and petrochemical plants when installed according to the rated standards and local regulations.
The unit uses a 280 frame with a cast iron enclosure and bearings specified as 6316/C3. The IM class is IMB3 IM1001, supporting reliable operation under vibrational loads and extended service life. The Terminator Box is located at D-End top, which benefits field wiring and maintenance access, simplifying retrofit and new-install projects in industrial settings.
Maintenance is typically reduced due to the robust cast iron frame, sealed IP55 enclosure, and explosion-proof design which lowers ingress risk. ROI is enhanced by IE3 efficiency and longer bearing life, translating into lower energy use and fewer shaft-bearing replacements. For best results, follow periodic inspection schedules, verify seals and cable glands, and coordinate with safety compliance teams to maintain certification status.
