ABB 3GJA353420-ADEIN 3-Phase motor - Exd flameproof

Exd flameproof protection enables intrinsic safety in explosive atmospheres, reducing ignition risk and enabling compliant operation in petrochemical and mining environments. This ABB motor combines Exd and Exdb protection with a robust cast-iron frame, supporting long service life in harsh sites where reliability matters most. The result is safer equipment, lower maintenance costs, and fewer unplanned shutdowns in hazardous areas, translating into predictable production and fewer compliance incidents for operators. IP55 protection guards against dust and water ingress, ensuring reliable performance in dusty plants, wash-down zones, and outdoor locations where moisture challenges are common. The 355 mm cast-iron frame provides rigidity and vibration resistance essential for high-load, continuous-duty operations; combined with precision bearings, it helps minimize unplanned maintenance. Together, these features reduce bearing wear, extend service intervals, and lower total cost of ownership in demanding environments. IE4 efficiency delivers measurable energy savings on continuous runs, with Full Load efficiency at 96.5% and strong partial-load performance around 96.4% at 75% and 95.7% at 50% load, improving operating costs across the S1 duty cycle. This efficiency also reduces heat generation, which complements longer bearing life and cooler operating temperatures in confined spaces. The 6-pole design optimizes torque delivery for standard 50 Hz industrial power, balancing speed with performance in a wide range of load conditions. Cast iron construction and higher-grade bearings (6322/C3 and 6316/C3) provide durability in high-load applications and challenging ambient conditions, delivering resilience against shock loads and shaft misalignment. The IM Class IMB3 IM1001 mounting arrangement supports straightforward installation and cross-brand compatibility, while the Terminator Box location D-End top offers convenient wiring access for maintenance. Designed for hazardous areas, the motor operates at ambient temperatures up to 50 °C and altitude to 1000 m, ensuring reliable performance across global sites. The combination of Exd/Exdb protection, IP55, IE4 efficiency, and a 355 frame makes it a versatile choice for retrofit projects or new builds in safety-critical industries where uptime and safety are non-negotiable.
