Exdb flameproof protection directly reduces risk in hazardous mining and other explosive atmospheres, enabling safe operation and regulatory compliance while maintaining continuous production. This feature translates to lower insurance costs and fewer shutdowns due to safety incidents, particularly in underground and surface mining environments where ignition sources must be controlled. IP66 protection ensures washdown resilience and dust ingress resistance, boosting uptime in harsh industrial settings and simplifying maintenance scheduling for long-running line drives. IE2 efficiency class delivers meaningful energy savings at full load and partial load, supporting a lower total cost of ownership and better sustainability metrics for heavy-duty conveyors and fans. The 250-frame cast iron construction and 6315M/C3 bearings provide rugged durability, enabling longer service life under high vibration and thermal cycling typical of mining motors. The top terminator box and IMB5 mounting compatibility simplify installation, reduce wiring errors, and enable modular upgrades across fleets in large industrial facilities. With a two-pole (2P) design and S1 duty, this motor offers reliable torque characteristics for constant-speed applications, minimizing torque ripple and delivering predictable performance in continuous processes. Overall, the unit integrates with standard 3-phase drives and meets international procurement expectations, offering a robust, retrofit-friendly solution for hazardous-area motor needs.

FAQs
Yes. This motor is designed for standard 3-phase systems and features IMB5 mounting compatibility with a top-mounted termination box, facilitating straightforward installation and wiring in new builds or retrofits. The two-pole design supports typical 50 Hz operation, while its S1 duty rating is suited to continuous operation in demanding environments.
Key specs include IE2 efficiency class under full-load conditions with typical full-load efficiency around 93.8% and partial-load values near 93.9% at 75%, IP66 ingress protection for harsh environments, Exdb flameproof protection for hazardous locations, and a 2-pole construction. Frame size is 250 with a cast-iron frame and heavy-duty bearings (6315M/C3).
Absolutely. The Exdb flameproof protection and IP66 rating make it well-suited for mining and other hazardous-area operations. The flameproof design protects against ignition in explosive atmospheres, while the rugged cast-iron frame and durable bearings support continuous operation under demanding conditions.
The motor features IP66 ingress protection and Exdb flameproof protection, plus IE2 efficiency. Additional attributes include IC411 insulation class and IMB5 IM3001 mounting classification. It is manufactured in Finland and carries a harmonized design suitable for international procurement and compliance expectations.
The combination of Exdb protection, IP66 resistance, and IE2 efficiency reduces downtime and energy costs, delivering lower total cost of ownership. The top-terminator box and robust bearings (6315M/C3) minimize wiring checks and wear, while the cast-iron frame and compact 2P design support longer service intervals and easier maintenance in demanding mining and heavy-industrial settings.
