FAQs
The 3GJA312820-BDP is designed for hazardous locations with Exdb flameproof protection and gas group IIB classification. Its IP55 rating and robust cast-iron frame support safe operation in potentially explosive atmospheres, while the coil insulation and enclosure meet stringent industrial safety standards. It integrates with standard ABB motors and aligns with common Ex-rated installation practices to simplify site authorization and commissioning.
Key electrical specs include IE4 efficiency, a 315 mm frame, 4-pole design, voltage code D, and three-phase operation. It features IP55 ingress protection and insulation class ICLF, along with Exdb flameproof protection. These specifications enable efficient, reliable operation in tough environments while meeting regulatory requirements for energy use and safety.
Yes. Its Exdb flameproof protection, 315 frame, and robust cast-iron construction make it a strong retrofit option for hazardous-area pumps and fans. The motor supports standard mounting (IMB5 IM3001) and offers reliable bearings (6319/C3) for long service life, reducing retrofit risk and downtime while maintaining compliance with explosion protection standards.
The Exdb flameproof design and IP55 protection minimize ingress-related wear, reducing maintenance intervals in harsh environments. The rugged cast-iron housing and durable bearings resist vibration and thermal stress, extending service life and lowering total cost of ownership. These factors translate to less frequent repairs and higher uptime for critical processes.
The motor complies with Exdb flameproof certification for gas group IIB, IP55 protection, and IE4 efficiency under IEC standards. Insulation class is ICLF, and the unit uses a 315 frame with a cast-iron housing. Typical documentation includes homologation certificates, installation manuals, and OEM safety data sheets for hazardous-area equipment.
