FAQs
The ABB 3GKP355420-ADG is a 3-phase motor with a D voltage code that supports standard industrial VFDs and variable-speed drives, provided the installation follows explosion-protection guidelines and the drive is configured for flameproof motors. Its single-speed, 10-pole design is optimized for reliable control in hazardous zones when paired with appropriate protected drives and proper wiring practices.
This motor features Exde flameproof protection suitable for explosive atmospheres, IP55 ingress protection, and a Gas Group IIB rating. It also uses insulation class ICLF and electrical class IC411, aligning with common hazardous-area standards. These certifications collectively support safe operation in chemical, oil & gas, and mining environments.
Yes. The unit is rated for continuous operation (S1 duty), designed for uninterrupted service in process automation. Its robust cast-iron frame, reliable bearings, and flameproof construction help maintain steady torque and reduce unexpected downtime, making it well-suited for long-run production lines and steady-state processes.
Maintenance should focus on bearing health (6322/C3 and 6316/C3) and enclosure integrity due to the IP55 rating. With a top-terminator box for convenient wiring and a rigid IMB3 IM1001 mounting class, inspections should include bearing lubrication intervals and inspection of the flameproof enclosure seals. The smart design minimizes unplanned maintenance when inspected per schedule.
Upgrading to this Exde flameproof motor can reduce downtime, improve safety compliance, and lower long-term maintenance costs due to robust construction and reliable insulation. With IE Class data showing high full-load efficiency around 94.6% and favorable partial-load performance, operators can expect energy savings alongside extended service life and easier regulatory adherence.
