FAQs
For Ex-rated installations, plan mounting on a 355 frame with a cast-iron enclosure and D-End top termination box. Ensure proper cable ingress protection to maintain IP55, verify Gas Group IIB suitability, and confirm ambient temperature not exceeding 40 °C or altitude beyond 1000 m. The motor supports standard ABB drive interfaces, simplifying integration with existing control systems.
This motor operates as a 3-phase squirrel cage with 6 poles, Duty S1, and Voltage Code D. It provides Exdb flameproof protection, IP55 ingress protection, and insulation class ICLF. It is designed for continuous operation (S1) in hazardous zones with IE4 efficiency, delivering reliable performance at full and partial loads as listed in its IE class data.
Yes. The AB B 3GJA353420-ADP is rated Exdb with Gas Group IIB protection, making it appropriate for hazardous areas where explosive atmospheres may be present. It’s designed to meet stringent safety requirements while delivering efficient operation in demanding process industries.
IE4 efficiency reduces energy consumption during both full-load and part-load conditions (as high as 97.0–97.1% at 100%/75% loads). In continuous-duty applications, this translates to meaningful annual energy savings, lower carbon footprint, and faster return on investment through reduced electricity bills and extended motor life.
Plan for periodic inspections of the cast-iron frame and bearings (6322/C3 and 6316/C3), with attention to IMB3 IM1001 mounting and D-End top access for quick servicing. The Exdb flameproof design reduces ignition risk, while solid construction supports longer service intervals. Regular lubrication, vibration checks, and insulation condition monitoring help maximize uptime in harsh environments.
