Feature IE3 efficiency with 355 kW output at 50 Hz translates into measurable energy savings and lower operating costs, especially in continuous-duty applications like pumps and fans. Business Impact Reduced energy consumption improves total cost of ownership and shortens payback periods on retrofit projects. Application Ideal for process cooling, material handling, and ventilation in demanding industrial plants where uptime matters. Feature IP55 enclosure and insulation class ICLF provide rugged protection against dust, moisture, and heat. Business Impact This enables longer intervals between maintenance and fewer unscheduled outages. Application Suitable for cement, mining, and chemical processing environments where dust and temperature fluctuations are routine. Feature EX protection with gas group IIC designation supports explosion-hazard compliance. Business Impact Enables safe operation in zones with potentially explosive atmospheres, reducing risk while simplifying regulatory alignment. Application Used in offshore platforms, refineries, and chemical plants with stringent safety requirements. Feature Cast-iron frame, 8 poles, frame size 400, bearings 6324/C3 and 6319/C3, and IMB3/IM1001 mounting. Business Impact Delivers rigidity and longevity for high-load duties with predictable service intervals. Application Suitable for heavy conveyors, crushers, and mills where precise alignment and durable bearings matter. Feature Top terminator box location and D connection configuration simplify electrical installation and service. Business Impact Accelerates commissioning and eases panel wiring, reducing installation time. Application Beneficial for retrofit projects and new builds with standard 400 V 50 Hz supply.

FAQs
This motor uses a D connection with 400 V 50 Hz supply, top-entry terminator box, and IMB3/IM1001 mounting. Ensure compatible switchgear, adequate space for the 400 mm frame, and crane access for the 3.2 metric ton unit. Verify ambient conditions up to 40 °C and altitude up to 1000 m and check IP55 enclosure requirements in dusty environments.
IE3 classification yields full-load efficiency around 94.6% at 50 Hz and ~95.0% at 60 Hz, translating to meaningful energy savings on long-running loads like pumps and fans. Operational benefits include lower heat generation, reduced cooling requirements, and a faster return on investment when paired with large horsepower motors such as 355 kW.
Yes. The motor is EX‑protected (Exec) with IIC gas group and dust-ignition‑proof design. It carries IP55 protection and IS designed for dust-prone, potentially explosive atmospheres, making it suitable for cement, chemical, and mining operations where regulatory compliance and safety are critical.
Key certifications include IE3 efficiency, IP55 enclosure, IC411 insulation classification, IMB3/IM1001 mounting, and EX protection. It is configured for 8 poles, 400 V operation, and supports hazardous-area installation with safe handling of high-temperature and dust-laden environments.
With cast-iron frame, 6324/C3 and 6319/C3 bearings, and top-mounted electricals, maintenance focuses on bearing wear and sealing integrity. Long bearing life and rugged construction reduce replacement frequency. Despite its heavy weight, standard dimensions and readily available spare parts support predictable maintenance and favorable total cost of ownership in heavy industry contexts.
