ABB 3GJA312830-ADCIN 3-Phase motor - Exd Flameproof

Exd flameproof protection is a defining feature that enables safe operation in ATEX/IECEx hazardous zones. The motor’s Exdb protection paired with a rugged cast-iron frame minimizes ignition risk and supports installation in challenging environments without expensive enclosure retrofits. This directly reduces compliance overhead and unplanned downtime while maintaining strong torque delivery in chemical plants, refineries, and offshore facilities. IP55 enclosure protection and IC411 insulation guard against dust, moisture, and temperature variation, extending service life in demanding environments. The 315 frame with a cast-iron housing resists vibration and impact in continuous duty, while the 4-pole design provides stable speed under load. Together, these features reduce maintenance cycles, lower spare-part costs, and streamline integration with standard drives across oil, gas, and mineral processing. IE2 efficiency aligns with continuous-process energy strategies, yielding meaningful operating-cost reductions. At full load, the motor delivers about 95.1% efficiency, with identical performance at 75% and 50% loads, while thermal design maintains capability in 50 °C ambient conditions. This combination supports lower lifetime energy consumption, reduced heat load on cooling systems, and better power factor management in pumping, fans, and conveyor drives. Robust mechanicals maximize uptime in vibration-heavy lines. The 315 frame uses a sturdy cast-iron housing, with high-precision bearings (6319/C3 and 6316/C3) that withstand misalignment and startup transients. The IMB3 IM1001 mounting classification simplifies retrofits in existing plant footprints, while the 1 piece MOQ and D-End top terminator box location reduce installation time. These factors translate to lower rebuild costs and faster time-to-full production. Operational limits and inspection-ready design support safer electrical installations. The motor is rated for S1 duty with ambient up to 50 °C and altitude up to 1000 m, while IP55 and Ex-protections satisfy regulatory requirements and internal safety standards. Having a familiar 4-pole, 315 frame form factor, coupled with a standard voltage code (D), makes procurement predictable and reduces total-cost-of-ownership over the motor’s life.
