Exdb flameproof protection and IP55 enclosure deliver safe operation in explosive atmospheres, reducing site risk and enabling compliant installations. This construction supports quick routine inspections and durable performance in harsh environments, minimizing unscheduled outages. Ideal for chemical processing, petrochemical, and mining applications where equipment integrity is non-negotiable. IE2 efficiency with Full Load 94.1% reduces energy costs on long-run operations. Lower energy consumption translates to smaller electrical bills and cooler running temperatures, extending motor life. This is particularly valuable for continuous S1 duty conveyors and pumps in hazardous zones because efficiency directly affects total cost of ownership. Cast-iron frame (280) and 665 kg weight provide high rigidity and vibration damping, supporting precise alignment and longer bearing life. The 6316/C3 bearings and IMB3 IM1001 class verify robust installation for frequent starts and stops typical in process lines. The D-End top terminator box simplifies field wiring during installation. Environmental tolerance includes ambient temperature up to 50 °C and altitude up to 1000 m, with insulation IC LF? (ICLF) supporting reliable operation. Flexible rotation with direction of rotation Both sides allows easy mounting in tight spaces and standard drive compatibility. The 2-pole design supports a compact footprint for typical process lines, with Exdb protection aligning with explosion-proof regulatory requirements.

FAQs
When installing this Exdb flameproof motor in hazardous zones, plan for proper enclosure sealing (IP55), flameproof cable entries, and a D-End top terminator box. Ensure ambient temperature stays within 50 °C and altitude remains under 1000 m. Use certified explosion-proof cables and verify grounding. Allow for reversible rotation mounting and compatible shaft alignment with existing drives to minimize mechanical stress and downtime.
IE2 efficiency, with Full Load around 94.1%, lowers electrical energy consumption during continuous operation. For S1 duty cycles prevalent in pumps and conveyors, these gains translate to reduced energy bills, cooler motor temperature, and longer bearing life due to lower operating stress. The result is a lower total cost of ownership and improved process reliability in hazardous environments.
This motor features Exdb flameproof protection, IP55 enclosure, and IC411 insulation, with Gas Group IIB classification. These attributes collectively support compliance in explosion-prone zones such as petrochemical plants and mining operations. Always confirm site-specific regulatory requirements and ensure proper integration with flameproof drives and protective relays.
Key mechanical specs include a Cast Iron frame (280) and a 665 kg product net weight with a 685 kg gross weight. Bearing configuration is 6316/C3, and the IM classification is IMB3 IM1001. Terminator box is located at the D-End top, supporting straightforward field wiring. Frame size and weight inform foundation design and alignment with existing motor trains.
Best suited for hazardous-area processes in oil, gas, chemical, and mining sectors requiring flameproof protection and robust mechanicals. As a 3-phase squirrel cage motor with Exdb protection and IE2 efficiency, it integrates with standard VFDs under proper safety practices and protective schemes. Verify drive compatibility and ensure wiring methods meet explosion-protection standards.
