ABB 3GLL312925-BDC 3Phase Synchronous Reluctance Motor - IE5
Part Number: 3GLL312925-BDC
Quick Summary
ABB 3GLL312925-BDC is a 550 kW IE5 water-cooled SynRM motor designed for demanding process and pump drives. This model helps combat energy waste and thermal overload in continuous operation by delivering premium efficiency at 400 V and 50 Hz. Operators often struggle with cooling capacity and space constraints; water cooling here minimizes heat buildup and supports compact, reliable installations. Key certifications and ratings include IP55 protection, IC71W insulation, and IE5 efficiency, all backed by a Finnish manufacturing standard. The motor’s aluminum frame and IMB5 IM3001 mounting class offer rugged durability with installation flexibility, while the D-End top terminal box simplifies wiring in confined spaces. Typical use cases span steel, chemical processing, and large-scale pumping where energy savings and uptime matter.

FAQs
ABB 3GLL312925-BDC is compatible with typical 400 V, 50 Hz industrial drives and uses a D-End top terminal box for convenient wiring. It features IP55 protection, IC71W insulation, and an aluminum frame with an IMB5 IM3001 mounting class. When installing, ensure proper water-cooling supply, secure mounting, and sufficient clearance for maintenance access.
Key electrical specs include 550 kW output, 400 V input at 50 Hz, 4 poles, and IC71W insulation. The IE5 efficiency rating provides full-load efficiency around 96.5%, with strong partial-load performance (96.4% at 75%). The motor features IP55 protection and a D-configuration connection suitable for rugged industrial environments.
This SynRM motor excels in heavy industries such as steel, chemical processing, water pumping, and large-scale fans or compressors. Its water-cooled design supports high-duty-cycle applications where heat rejection is challenging, while the IE5 efficiency helps reduce energy costs in continuous-operation processes and large pump systems.
The motor meets IE5 efficiency, IP55 protection, and IC71W insulation standards, with additional attributes like IC LH insulation and a Finnish origin. It also carries UNSPSC 26101100 coding and a customs tariff number of 85015394, supporting regulatory and procurement documentation for global supply chains.
Maintenance focuses on reliable cooling water supply, periodic bearing checks, and inspection of the D-End top terminal box. ROI benefits come from energy savings due to IE5 efficiency, reduced cooling infrastructure needs, and improved uptime from IP55 protection and robust IMB5 IM3001 mounting, delivering lower total cost of ownership over the motor’s life cycle.
