Exdb flameproof protection translates into safer operation in hazardous zones, reducing the risk of ignition from electrical equipment and enabling compliance with harsh-environment standards. This improves uptime and reduces costly non-production downtime, especially in chemical and petrochemical plants. IE2 efficiency combined with a four-pole design delivers predictable torque and energy savings, supporting sustainable operation and lower total cost of ownership in high-load conveyor or pump applications. Cast iron frame 355 and bearings 6322/C3 provide durability and vibration resistance under heavy-duty service and long life in demanding environments. IP55 protection guards against dust and water ingress, enhancing reliability in wet or dusty plant floors. Installation advantages include a standard ABB M2JAP designation with D-End top termination, facilitating retrofits and compatibility with existing drives. The motor is specified for ambient temperatures up to 50 °C at up to 1000 m altitude with an IC411 insulation class, ensuring consistent performance in hot, high-altitude sites and reducing spare-part diversity for global projects.

FAQs
For hazardous areas, use the Exdb flameproof motor with IP55 protection to minimize ignition risk and withstand dust and moisture. The motor carries a cast iron 355 frame and a D-End top termination box location for straightforward wiring. It is designed for a 355MLB 4 designation and a heavy-weight installation, so plan crane access and secured mounting. Ensure the environment stays within 50 °C ambient and up to 1000 m altitude for optimal performance.
IE2 indicates a baseline efficiency suitable for many industrial drives, delivering energy savings at full load. For this 4-pole, S1 duty motor, Full Load efficiency is around 95.1%, with nearly the same at partial loads (75% and 50%). This translates to lower operating costs over the motor’s life, especially in continuous-duty applications such as pumps and fans and with reliable, predictable torque curves.
Yes. The motor is rated for an ambient temperature of up to 50 °C and a maximum altitude of 1000 m, making it suitable for hot plants and mid-altitude installations. Pairing with good cooling and proper cable sizing will help maintain rated performance in challenging environments typical of chemical plants and mining operations.
Key certifications and protections include Exdb flameproof protection for hazardous environments, IP55 ingress protection, and IC411 insulation class. The motor also features Gas Group IIB protection, Temperature Class T4, and IE2 efficiency with a 4-pole design under S1 duty. These attributes support compliance in regulated facilities and safer operation in explosive atmospheres.
The motor uses a cast iron frame 355 with bearings 6322/C3 and 6316/C3, and weighs about 2330 kg. While heavier, this design delivers robust durability, longer service life, and reduced vibration in demanding loads. Plan for heavy equipment handling during installation, and ensure bearing maintenance schedules align with the IM class (IMB3 IM1001) for reliable uptime and lower lifecycle costs.
