Exdb flameproof protection combined with IP55 enclosure provides safe operation in explosive atmospheres. This design minimizes ignition risks from electrical arcs during startup and normal running while resisting dust and water ingress. The result is improved plant safety and predictable availability for critical processes in chemical and petrochemical facilities. IE4 energy efficiency improves operating costs for continuous-duty motors. With Full Load efficiency near 97.4% at 50 Hz and 97.2% at 60 Hz, energy bills drop under steady operation. This performance helps facilities reduce CO2 footprint while maintaining reliable torque. The rugged mechanical build pairs a Cast Iron frame (355) with 6322/C3 and 6316/C3 bearings for longevity in vibration-prone installations. The IM Class IMB3 IM1001 supports balanced performance and smoother starts, translating to lower maintenance costs and fewer unscheduled outages. A 355 frame, 4-pole configuration, and D-End top termination box simplify mounting, wiring, and service in tight electrical rooms. This saves installation time and reduces field-wiring errors, especially when integrating with standard ABB control panels or drives. The motor operates in S1 duty with an insulation class ICLF and temperature class T4, tolerating 40 °C ambient conditions and up to 1000 m altitude. These ratings expand deployment options in hot, high-altitude plants such as chemical processing, mining, and offshore facilities. Direction of rotation on both sides offers installation flexibility for belt, pulley, or coupling arrangements, enabling quick reconfiguration during plant changes without rewiring. Overall, the Exdb protection, IP55, and robust mechanical design support long service life and predictable ownership costs.

FAQs
The motor is designed as a flameproof Exdb device with IP55 protection, allowing direct installation in hazardous zones alongside AB B drives and control panels. The D-End top termination simplifies wiring in tight spaces, while the 355 frame and 4-pole configuration align with common mounting patterns. When retrofitting, verify enclosure spacing and motor starter compatibility to ensure clean integration.
This ABB motor meets IE4 efficiency across both 50 Hz and 60 Hz operation. At 50 Hz full-load efficiency is about 97.4%, with partial-load values around 97.6% at 75% and 97.5% at 50%. At 60 Hz, full-load efficiency is 97.2% with partial-load values near 97.2% at 75% and 96.8% at 50%. These figures support energy savings in continuous-duty systems.
Yes. The Exdb flameproof protection combined with IP55 enclosure is intended for hazardous areas, including chemical processing and oil-and-gas pump drives. With a 355 mm cast-iron frame, 4-pole design, and 40 °C ambient tolerance, it handles continuous S1 duty with reliable starts and reduced vibration. Always confirm site-specific certifications and installation clearances.
Key protections include Exdb flameproof protection and IP55 enclosure for hazardous environments, along with an insulation class ICLF and temperature class T4 for hot processes. The motor supports operation up to 1000 m altitude and 40 °C ambient temperature, with a 4-pole, 355 frame, and robust cast-iron construction. Gas group IIB and bearing configurations add to its protection profile.
Energy savings from IE4 efficiency reduce operating costs in continuous-duty drives, contributing to a shorter payback period. The rugged cast-iron frame and shielded bearings extend service intervals and lower replacement costs, while the D-End top termination and 355 frame simplify field wiring and maintenance. Overall, reliability in hazardous areas supports reduced downtime and higher asset utilization.
