The Exdbeb flameproof enclosure enables safe operation in hazardous environments, reducing ignition risk and helping you meet ATEX/IECEx requirements while keeping production online. This protection translates to fewer unplanned shutdowns in chemical plants and mines, supporting continuous operation and compliance. The motor delivers 450 kW at 500 V and 50 Hz with a 6-pole design, providing strong torque and consistent speed for demanding pumps, conveyors, and mixers, lowering belt wear and process oscillations. IP55 protection guards against dust and moisture ingress, extending service intervals and lowering maintenance costs in harsh environments such as outdoor yards and plant rooms. The 400-frame cast-iron construction paired with IMB3/IM1001 mounting simplifies installation and future retrofits, enabling quicker commissioning and a streamlined spare-parts strategy for ABB drives and automation systems. Operating at temperatures up to 40 °C and altitude up to 1000 m, the motor maintains performance in multi-site deployments, while the IC LF insulation and IC411 class ensure electrical integrity under demanding operating conditions. The Delta (D) connection supports standard electrical configurations for reliable integration with existing plant power distribution, reducing wiring complexity and commissioning time. Together, these features drive energy efficiency, safety compliance, and predictable maintenance planning across harsh industrial applications.

FAQs
Install the 3GKP403520-AEK using IMB3/IM1001 mounting and the top-terminator box with a Delta (D) connection. This 6-pole, 400 frame unit operates at 500 V, 50 Hz, IP55, and Exdbeb protection for hazardous areas. Ensure site altitude remains below 1000 m and ambient temperature under 40 °C, with Gas Group IIB compliance prior to commissioning.
IE3 premium efficiency reduces energy losses across full and partial loads, lowering operating costs over the motor’s life. Exdbeb flameproof protection safeguards personnel and facilities in explosive atmospheres, enabling reliable operation in IIB environments. The combination supports strong torque delivery at 450 kW and dependable speed control for demanding process applications.
Yes. The ABB 3GKP403520-AEK is designed for hazardous-area duties with Exdbeb protection, IP55 enclosure, and robust mounting (IMB3/IM1001). With 450 kW output, 6 poles, 1000 m altitude rating, and 40 °C ambient tolerance, it is well-suited for mining conveyors, pumps, and chemical process equipment in challenging environments.
Key certifications include Exdbeb explosion protection for gas environments, IP55 ingress protection, and IC411 insulation rating, plus Gas Group IIB.
