Flameproof Exdbeb protection with IP55 enclosure safeguards personnel and equipment in ATEX zones, enabling reliable operation in ATEX zones, petrochemical, and mining environments. The rugged cast-iron frame (size 355) pairs with the Exdbeb flameproof system to deliver consistent torque under start-up and load conditions while preserving safe installation clearance. This design minimizes ignition risks and reduces unplanned downtime, supporting compliance with explosion-protection standards and straightforward maintenance planning. IE3 premium efficiency translates into measurable energy savings on continuous duty. At 50 Hz, full-load efficiency is about 95.8%, with partial loads still above 95.0%, which lowers operating costs and heat generation. The higher efficiency also reduces cooling requirements, enabling smaller drives and lower capital expenditure in new installations. Installation and compatibility are streamlined by IMB5/IM3001 mounting and a top terminal box. The motor is a 2-pole design rated for 500 V and 50 Hz, with a D connection and a frame size 355, making retrofits and new builds more predictable and easier to document in control schematics. Environmental and mechanical robustness are built in: IP55 enclosure, ambient temperature rating up to 40 °C, altitude up to 1000 m, and ICFL insulation class. The cast-iron housing, bearing 6316M/C3, and IMB5 IM3001 mounting ensure long life in harsh process environments. Operational readiness and support are reinforced by a Finland origin and flexible ordering (minimum 1 piece). The product is designed for continuous S1 duty with safe, reliable integration into ABB drive ecosystems, delivering predictable ROI through improved reliability and energy performance.
