FAQs
ABB 3GJM251210-BEK uses a Delta (D) connection configuration for 500 V supply. For correct installation, connect windings in Delta to achieve the 500 V line voltage, ensure proper alignment with IMB5/IM3001 mounting, and verify drive compatibility with a 50 Hz, 2-pole system. Follow standard safety procedures and consult the installation manual for torque values on mounting bolts and connector torque specs to preserve insulation integrity.
This motor features IP66 ingress protection for dust and water resistance and Exdb flameproof protection suitable for hazardous zones, aligning with mining safety requirements. The IE3 efficiency rating supports energy compliance, while the 2-pole, frame 250 design is compatible with standard mining drive trains. While SIL or CE markings aren’t listed in the data, the combination of IP66, Exdb, and IE3 demonstrates robust regulatory alignment for hazardous-location applications.
Yes. The 3GJM251210-BEK is specified for operation up to 1000 meters in altitude and ambient temperatures up to 40 °C. This enhances thermal management and keeps performance within rated torque and speed under demanding mining conditions. When selecting drive and cooling solutions, confirm enclosure sealing and ventilation to maintain IE3 efficiency across duty cycles.
The motor uses a Cast Iron frame size 250 with IMB5 IM3001 mounting and a top terminator box location. This combination supports straightforward installation, easy alignment with standard drives, and compatibility with retrofit projects. The 2-pole, 55 kW, 500 V configuration pairs well with common conveyor, pump, and fan installations in hazardous environments.
IE3 premium efficiency reduces energy consumption during continuous operation, delivering lower operating costs over the motor’s lifecycle. The reliable Exdb flameproof build and IP66 rating contribute to reduced maintenance frequency by protecting internal components from harsh mine conditions. For operators, this translates into higher up-time, lower energy bills, and more predictable maintenance planning.
