Feature → Business Impact → Application: Exdb flameproof protection enables operation in hazardous areas with gas group IIB, reducing the risk of ignition and enabling safer plant operations. This directly improves compliance and uptime for petrochemical processing lines, refineries, and offshore platforms. Feature → Application → Benefit: IP55 enclosure provides robust dust and water ingress protection, extending service intervals in dusty or high-moisture environments such as cement plants or mining conveyors, translating to lower maintenance costs and fewer unplanned shutdowns. Feature → Business Impact → Application: IE4 efficiency with Full Load around 97% and partial-load performance near 97% supports meaningful energy reductions on continuous-duty drives, resulting in lower energy bills and improved ROI for pumping, fans, and compressor systems. Feature → Application → Benefit: 355 mm cast-iron frame and 6-pole design deliver high torque at start-up and steady operation, ideal for heavy conveyors, dosers, and pumps requiring reliable torque curves under full-load conditions. Feature → Compatibility → Benefit: IEC-compatible dimensions and a D-end top terminator box simplify replacement, retrofits, and integration with existing control panels, reducing installation time and minimizing downtime. Feature → Operating envelope → Benefit: Ambient temperature up to 40 °C and altitude up to 1000 m expand where this motor can be deployed, supporting global installations from desert sites to elevated facilities while maintaining performance and safety margins.

FAQs
This motor uses a 355-frame cast-iron design with a D-End top terminator box, matching common IEC mounting standards for easy retrofit. It supports a 6-pole configuration and is suitable for standard conveyor, pump, and fan drives in hazardous environments, ensuring straightforward alignment with existing electrical cabinets and mechanical mounts.
At 50 Hz, IE4 efficiency is confirmed with Full Load around 97.0% and Partial Load figures near 97.1% (75%) and 96.9% (50%). At 60 Hz, Full Load is 97.0% with Partial Load around 97.0% (75%) and 96.4% (50%). These values support high energy efficiency under continuous-duty (S1) operation.
Best-suited applications include petrochemical processing, mining conveyors, and refinery pumps where gas group IIB and flameproof Exdb protection are required. The motor's IP55 enclosure and IE4 efficiency support safe, reliable operation in challenging ambient conditions up to 40 °C and elevations up to 1000 m.
Key compliance markers include Exdb flameproof protection for hazardous environments, IP55 ingress protection, and IEC IE4 energy efficiency. Additional electrical and mechanical details—such as IC411 insulation class and 355 frame with cast-iron construction—support robust performance and long service life in demanding industrial settings.
The robust cast-iron frame, sealed-for-life bearings, and flameproof construction reduce maintenance intervals and downtime in harsh environments. With IE4 efficiency and reliable Exdb protection, operators typically see lower energy costs and longer mean time between failures, improving total cost of ownership in continuous-duty applications.
