Flameproof Exdbeb protection delivers enhanced safety in IIB gas groups, reducing risk and enabling safer operation in hazardous environments. Business impact: regulatory compliance, minimized incident costs, and lower insurance exposure; Application: chemical plants, refineries, and mining sites where explosion protection is mandatory. The IE3 premium efficiency rating translates to tangible energy savings and cooler running temperatures, decreasing operating costs and extending bearing life; Application: 400 kW drives for pumps and fans at 50 Hz, with documented full-load efficiency around 96% at 100% load. IP55 enclosure adds dust and water ingress protection, enabling longer service intervals in dusty or outdoor facilities; Application: mining conveyors, wastewater treatment, and process lines. The 4-pole, 355 frame with delta connection (D) provides stable torque and easy integration with 500 V supplies; Application: standard industrial drives with robust startup characteristics. Cast-iron frame and IMB5/IM3001 mounting support long service life and straightforward installation in space-constrained or retrofit projects; Application: retrofits and new builds in heavy industries. The motor’s ambient tolerance of 40 °C and altitude up to 1000 m ensures reliable operation in diverse sites, while Ex protection helps meet local explosion protection regulations. All told, this motor pairs strong mechanical robustness with safety-compliant design to reduce downtime and total cost of ownership across hazardous-area applications.

FAQs
This motor uses a D (Delta) connection suitable for 500 V supply and 50 Hz operation. When wiring, ensure correct phase alignment and secure terminal box access for IMB5/IM3001 mounting. Verify the top-terminator box location and provide adequate space for heat dissipation in IP55 environments. Use proper torque on all electrical connections to minimize resistance and heat buildup.
Exdbeb denotes flameproof protection designed to contain internal explosions and prevent ignition of surrounding atmospheres. For IIB gas groups, this means the motor can operate in explosive zones with reduced risk of flame propagation. In practice, this supports regulatory compliance, safer maintenance routines, and the ability to run critical processes like pumps and conveyors without unnecessary downtime.
The unit is specified for 50 Hz (4-pole, 500 V, 400 kW). IE3 efficiency data at 60 Hz indicates similar high efficiency, but you should confirm the exact torque and current ratings for your 60 Hz system with a qualified drive engineer. If a 60 Hz condition is required, consult ABB for any derating or frame- and bearing-related considerations to ensure safe operation.
Industries such as chemical processing, oil and gas, mining, and wastewater treatment benefit from its hazardous-area protection, IP55 enclosure, and premium efficiency. The motor supports robust maintenance schedules and energy cost savings, particularly in continuous-duty S1 applications with demanding environmental conditions and space-limited installations.
IE3 efficiency reduces energy losses at full and part load, lowering operating costs and cooling requirements. Flameproof protection minimizes unplanned downtime due to ignition risks in hazardous zones, enabling safer, longer service intervals. Combined, these features lower total cost of ownership through energy savings, extended motor life, and improved process reliability in demanding industrial environments.
