FAQs
The motor adopts Exdb flameproof protection and an IP55 enclosure, designed for IECEx/ATEX environments. It integrates with common VFDs for 4-pole, 50/60 Hz operation, providing smooth speed control while maintaining compliance in hazardous zones. Ensure mounting aligns with the 315 frame footprint and verify ambient temperature limits (up to 50 °C) are respected.
Key specifications include IE3 efficiency with full-load around 96%, voltage code D, 4 poles, and a 315 frame. Ambient temperature up to 50 °C, altitude up to 1000 m, IP55 protection, and IC411 insulation. Gas group IIB and Exdb protection indicate suitability for hazardous-area pumps, fans, and mixers in petrochemical settings.
Yes. The Exdb flameproof protection and IIB gas group designation align with ATEX/IECEx requirements for Zone 1/2 hazardous areas. The IP55 rating adds environmental protection, while IE3 efficiency supports energy-performance expectations in regulated facilities like refineries and chemical plants.
The combination of IE3 efficiency, a rugged cast-iron frame, and sturdy bearings reduces energy consumption and maintenance intervals, lowering operating costs. Its flameproof design minimizes ignition-related risk, decreasing downtime. A reliable 315 frame aids standardization, enabling easier spare parts management and faster repair turnaround.
Plan for preventive lubrication and bearing checks for 6319/C3 and 6316/C3 assemblies, monitor insulation integrity (ICLF), and maintain IP55 seals against dust and water ingress. Ensure terminator box location (D-End top) suits your wiring layout, and verify ambient conditions remain within 50 °C and altitude limits to sustain performance.
