Exdbeb flameproof protection is built into the ABB 3GKP354420-BEK, delivering certified safety in explosive atmospheres while maintaining reliable operation. The IP55 enclosure and IC411 insulation protect windings from dust, moisture, and aggressive temperatures typical of process plants. Designed for IMB5/IM3001 mounting with a top-placed terminator box, it also eases retrofit and new-install work in space-constrained facilities. IE3 efficiency is a core differentiator, with full-load performance around 94.6% at 50 Hz and nearly 94.8% at 75% load, reducing energy consumption and cooling requirements. The motor delivers 250 kW at 500 V, providing strong torque for demanding line starts without oversizing drives. This combination translates to lower lifecycle costs and improved process stability across continuous-duty operations. Frame 355 and cast-iron construction pair with bearings 6322/C3 and 6316/C3 to withstand demanding environments, while IMB5/IM3001 mounting supports common industry configurations. The 8-pole design delivers smooth start-stop behavior and predictable speed control in S1 duty at 50 Hz and 60 Hz. Its dimensions—1584 mm length, 968 mm height, and 700 mm width—and a net weight of 2224 kg help with installation planning and crane requirements. Designed for hazardous locations, this motor supports up to 1000 m altitude and 40 °C ambient, ensuring reliable operation across global sites. Exdbeb flameproof protection, IP55 enclosure, and IIB gas group certifications help meet stringent safety and regulatory criteria while maintaining long service intervals. In practice, the motor reduces energy costs and cuts maintenance downtime for heavy-process industries.
