FAQs
This motor is built with Exdbeb flameproof protection and an IP55 enclosure, suitable for hazardous zones. It uses a D (Delta) connection configuration and IMB3/IM1001 mounting, which simplifies installation in restricted spaces. With a 1000 m altitude and 40 C ambient limit, plan for appropriate cooling and clearance to maintain performance and safety in harsh environments.
Exdbeb protection prevents ignition sources in explosive atmospheres, reducing the likelihood of internal faults triggering hazards. Regular inspections should verify integrity of the flameproof joints and cabling, while the IP55 enclosure protects against dust and water ingress. Overall, Ex protection enhances operator safety and permits compliant maintenance procedures in refineries and chemical plants.
Yes. The 3GKP352420-AEK delivers 400 kW at 500 V and 50 Hz with a 4-pole design, suitable for high-torque, continuous-duty operations. It supports S1 duty and IMB3/IM1001 mounting, making it a reliable choice for continuous pumping and conveying systems in hazardous environments.
IE3 premium efficiency reduces I2R losses under full and partial loads, delivering lower energy consumption compared with standard efficiency motors. In continuous-duty applications, this translates to measurable savings on electricity, reduced heat load, and lower total cost of ownership over the motor’s service life, particularly in facilities with large fleets of drives operating near full load.
The motor features Ex protection (Exdbeb) for hazardous areas, IP55 enclosure, and IC411 insulation. It also carries a Gas Group IIB rating and a T4 temperature class, aligning with ATEX/IECEx requirements. Additional compliance markers include robust IMB3/IM1001 mounting compatibility and 50 Hz operation for industrial-scale drive systems.
