FAQs
Installation should follow ATEX/IECEx guidelines for Exdb flameproof equipment. Use a compliant explosion-protected enclosure, ensure the terminating box is located on the D-End top as specified, and verify IP55 seals and grounding. The 355 frame and cast-iron housing provide rugged support, while IMB5 IM3001 mounting ensures proper alignment and vibration control. Always consult the product’s official data for torque and tightening sequences and perform a pre-commissioning test in a controlled area before live operation.
The motor is IE4-rated with Full Load efficiency around 97.2% at 50 Hz and 97.0% at 60 Hz, with partial-load performance near 97.0–97.2%. Voltage code is D, Duty is S1, and it is designed for 2-pole operation. Electrical data are supported by an IP55, IC411 insulation class, and a flameproof Exdb protection, making it suitable for continuous, heavy-duty use in demanding environments.
Yes. The ABB 3GJA351220-BDP features Exdb flameproof protection suitable for gas group IIB and hazardous-area installations. It carries IP55 ingress protection and an IC411 insulation class, aligning with stringent ATEX/IECEx requirements. This combination is designed for safe operation in explosive atmospheres while maintaining high efficiency and reliability.
The motor uses a 355 frame with a cast-iron housing and 2-pole configuration. Key internal dimensions include a product net length of 1409 mm, net height 1077 mm, and net width 800 mm, with an approximate weight of 1934 kg. These specs support straightforward mounting on standard bases, with a D-End top termination box arrangement to ease electrical connection and service access.
IE4 efficiency translates to meaningful energy savings, especially in constant or high-load operations. With Full Load efficiencies around 97% at both 50 Hz and 60 Hz, operators can reduce energy consumption compared with lower-efficiency designs, lowering annual energy costs. While exact ROI depends on load profiles and duty cycles, the combination of energy savings, reduced maintenance needs, and compliance-ready protection often yields a favorable total cost of ownership over the motor’s lifecycle.
