Exdb flameproof protection provides essential safety for explosive atmospheres, reducing ignition risks and helping you meet stringent mining and industrial safety standards. This directly lowers potential downtime and regulatory exposure while enabling continuous operation in hazardous areas. IP66 enclosure protects against dust ingress and powerful water jets, minimizing maintenance cycles in dusty belts, wet plants, or outdoor installations—translating to higher uptime and lower lifecycle costs. The 280 cast-iron frame and 6316/C3 bearings deliver rugged reliability, supporting long service intervals and smoother vibration performance in crusher feeders and long-wall conveyors. IE2 efficiency delivers measurable energy savings across 50/60 Hz operations, reducing operating costs on high-load cycles and improving overall site economics. The IMB5 mounting, top terminal box, and 2-pole design simplify installation, retrofits, and drive integration with standard ABB equipment. Designed for up to 40 °C ambient conditions at altitudes up to 1000 m, this motor maintains performance in demanding surface and underground environments. With Exdb protection and robust insulation (ICLF), it remains a cost-efficient solution for hazardous-area mining plants while delivering predictable maintenance needs and extended bearing life.

FAQs
This motor features a 280 frame in cast-iron housing with IMB5 mounting and a top-position terminator box, designed for straightforward retrofit into existing conveyors and mining drives. It supports standard 3-phase drives, operates at 50/60 Hz with IE2 efficiency, and is suitable for installations up to 1000 m altitude and 40 °C ambient conditions, simplifying site integration.
Key specs include Exdb flameproof protection, IP66 enclosure, ICFL insulation, a 2-pole configuration for strong starting torque, and IE2 efficiency. The motor is rated for S1 duty, providing continuous operation with predictable torque and reliability in demanding mining or processing applications, while the 6316/C3 bearings support long bearing life under vibration and dust exposure.
Yes. The Exdb flameproof protection, IP66 ingress protection, and robust cast-iron frame are specifically chosen for hazardous-area use. It is designed for continuous duty in mining, conveyors, crushers, and other heavy-industry tasks where ignition risk and harsh conditions necessitate certified protective features and durable construction.
Exdb explosion protection certifies suitability for explosive atmospheres, while IP66 ensures dust and water ingress protection. The insulation class ICFL and IMB5 mounting further support reliability and safe operation in demanding environments, aligning with industry standards for mining motors and hazardous-area equipment.
The combination of Exdb protection, IP66 sealing, and IE2 efficiency reduces downtime and energy costs, delivering a lower total cost of ownership. The rugged frame, bearing design, and top-Box wiring simplify maintenance tasks and extend service intervals, contributing to faster payback in long-life mining and processing installations.
