Feature: Exdb flameproof protection and IP66 enclosure shield the motor from explosive atmospheres and dust ingress, delivering proven safety in hazardous zones. Business impact: This reduces ignition risk, minimizes unplanned downtime, and lowers total cost of ownership in mining and processing facilities. Application: Ideal for underground conveyors, crushers, and hoisting equipment where explosion protection and rugged sealing matter. Feature: IE2 energy efficiency with Full Load 92.2% at 100% load (and 92.5% at 75% load, 91.8% at 50%). Business impact: Lower energy consumption and operating costs in continuous duty applications. Application: Suitable for material handling, grinding, and other constant-speed drives in mineral processing. Feature: Cast-iron frame, frame size 250, bearings 6315/C3 and 6313/C3, IM Class IMB3 IM1001, and top-termination box. Business impact: Durable, vibration-resistant construction that extends bearing life and simplifies maintenance in tough environments. Application: Heavy-duty mining motors and industrial drives where reliability is critical. Feature: Duty S1, ambient 40 °C, altitude 1000 m, IP66, IC411 insulation, insulation class ICLF. Business impact: Predictable performance across a broad operating envelope with consistent full-load results, enabling planning and uptime. Application: Continuous-duty drives in elevated, hot, dusty sites such as surface plants and shaft operations. Feature: 6 poles, 250 frame, top-box layout and Exdb protection in a Finland-origin design. Business impact: Compatibility with standard mounting footprints and easy retrofits in existing installations, with reliable supply and support. Application: Retrofits and new builds in hazardous locations requiring robust, explosion-protected motors.

FAQs
Plan for top-entry termination box access, ensure compliant flameproof cable glands, and maintain clearances for cooling. Confirm mounting on a rigid, vibration-damped base and verify alignment with standard footprint for a 250 frame. Use shielded cables in hazardous zones and follow local ATEX/IECEx requirements during commissioning.
It delivers IE2 efficiency with Full Load around 92.2% at 100% load, and 92.5% at 75% load, with 91.8% at 50% load. The motor is a 6-pole design (frame size 250) with a voltage code of S and a continuous S1 duty class, suitable for steady-state operations in challenging environments.
Yes. It features Exdb flameproof protection and an IP66 enclosure, engineered for hazardous zones in mining and heavy industrial plants. The combination supports safe operation in explosive atmospheres while delivering reliable, continuous-duty performance.
Exdb denotes flameproof explosion protection for mines and other hazardous areas. Coupled with IP66 ingress protection and IC411 insulation, the motor meets stringent safety requirements and supports compliance with ATEX/IECEx standards where applicable.
Energy efficiency (IE2) reduces operating costs over time, while the robust cast-iron frame and bearings extend service intervals and uptime. The top-entry box simplifies maintenance access, and the motor’s rugged build supports longer life in harsh environments, improving overall return on investment for continuous-duty applications.
