FAQs
This motor uses a 355 frame with a D-End top terminator box, enabling straightforward top-wiring. When installing in hazardous zones, ensure Exdb flameproof protection is maintained, IP55 enclosure integrity is preserved, and proper cable entries are used. Plan for a 2646 kg unit with standard ABB mounting patterns to minimize retrofitting and reduce commissioning time.
IE4 efficiency indicates lower energy losses during full-load and partial-load operation. Specifically, this model achieves high efficiency at 100% load (about 97%+) at 50 Hz and similar performance at 60 Hz, reducing cooling load and utility consumption. Over extended runtimes, this translates into meaningful energy cost savings and improved energy performance indicators.
Yes. The motor supports rotation in both directions, which provides installation flexibility in tight spaces and with reversible process lines. Coupled with the D-End top terminator box, wiring can be aligned with existing control cabinets, simplifying startup sequencing and maintenance rotation changes without major rework.
The unit provides Exdb flameproof protection, IP55 ingress protection, and Gas Group IIB classification with a T4 temperature class and ICLF insulation. This combination supports regulatory compliance across many regions, enabling safer operation in refineries, chemical plants, and mining facilities and easing CE and regional conformity efforts.
The cast-iron 355 frame, sturdy bearings (6322/C3 and 6316/C3), and robust IM class (IMB5 IM3001) design deliver long service life with reduced downtime. With minimal Make-To-Order considerations and standard packaging, the total cost of ownership decreases through fewer maintenance interventions and lower energy use, supporting a faster return on investment.
