FAQs
The motor uses a D connection configuration with a D-End top terminator box, designed for straightforward wiring to standard 400 V, 50 Hz systems. It mounts on IMB3/IM1001 configurations and relies on a frame size 400 cast-iron housing. Verify the IP55 enclosure and ensure the VFD or soft starter is compatible with Exdb-rated motors. Follow the datasheet installation guidance for gasket integrity and torque specs to maintain flameproof integrity.
At 50 Hz, the motor delivers 450 kW output with IE4 efficiency. The full-load efficiency is 96.6%, with 75% load at ~96.4% and 50% load at ~95.5%, under S1 continuous duty. It is a 6-pole unit, rated for IC411 insulation, and operates in ambient up to 40 °C at altitudes up to 1000 m, ensuring stable performance in demanding installations.
Yes. The ABB 3GJP403820-ADM features Exdb flameproof protection with Gas Group IIB, IP55 enclosure, and IC411 insulation, making it well-suited for hazardous zones. Its robust frame, IMB3/IM1001 mounting, and 6-pole design optimize reliability in challenging conditions typical of oil & gas refineries, chemical processing, and mining operations.
Key compliance features include Exdb flameproof protection for hazardous areas, IP55 enclosure protection, IE4 efficiency, and IC411 insulation. The motor is designed for use in gas environments (Gas Group IIB) and supports S1 duty with a 400 V, 50 Hz supply, enabling safe operation within ATEX/IECEx-related regulatory frameworks.
The motor’s robust cast-iron frame, high-quality bearings (6324/C3 and 6319/C3), and IMB3/IM1001 mounting reduce vibration and wear, extending service intervals. IE4 efficiency lowers energy costs over time, improving ROI in continuous-duty applications. With a 1000 m altitude tolerance and 40 °C ambient rating, it remains reliable in remote or harsh sites, delivering predictable total cost of ownership.
