ABB 3GJA312220-BDDIN 3-Phase squirrel cage motor - Exd IE3 IP55

IE3 efficiency delivers measurable energy savings for continuous-duty applications. The 3GJA motor achieves about 94.9% full-load efficiency at 50 Hz with 75% partial-load at 95.1% and 50% partial-load at 94.7%, reducing operating costs in pumps and fans while meeting stringent energy regulations. This makes it a strong choice for hazardous-area installations in industries like oil and gas, chemical processing, and mining. Exdb flameproof protection combined with IP55 enclosure provides safe operation in explosive atmospheres and dusty environments. This reliability minimizes ignition risk, protects critical uptime, and simplifies compliance with hazardous-area standards. The motor is designed for Exd protection and Gas Group IIB service, supporting safe integration in zone-rated facilities and certified maintenance programs. Rugged mechanical construction uses a cast iron frame in size 315 with high-capacity bearings (6319/C3 and 6316/C3) for long service life under continuous operation. The IMB5 IM3001 mounting class and D-End top terminal box orientation facilitate easier installation and maintenance in confined spaces. These features reduce bearing and mechanical failures, lowering maintenance costs and downtime. Operating flexibility is supported by an insulation class ICLF, temperature class T4, and environmental allowances of up to 50 °C ambient and 1000 m altitude. Such specs ensure consistent performance in hot plants and moderate elevations, while the 4-pole design delivers predictable torque and start-up behavior for pumps and blowers in industrial automation. Designed for reliability in critical processes, this motor supports S1 duty with a 1-piece minimum order and standard 315 frame. Its 4-pole configuration, ability to rotate in both directions, and robust termination options on the D-End top improve compatibility with existing drives and control panels, reducing integration risk in new builds.
