ABB M3BJ 315LKC 12 3-Phase squirrel cage motor - IP55

Cast Iron frame and 315 frame size deliver rugged mechanical strength suitable for aggressive industrial environments. The 12-pole design provides smooth torque and predictable starting characteristics, reducing peak electrical demand and wear on couplings and belts. By aligning with standard ABB M3BJ families, the motor offers straightforward substitution in existing plants and minimizes downtime during retrofits in pumps, fans, and conveyors. IP55 protection and IC411 electrical class ensure reliable operation in dusty and damp facilities. Sealed windings and a robust insulation system help resist temperature swings, while the ICLF insulation class supports long service life at elevated ambient temperatures. This translates to fewer unplanned outages and lower maintenance costs in food processing, water treatment, and mining sites. Ambient temperature up to 40 °C and altitude up to 1000 m make this motor suitable for many geographic locations without derating. The 1000 m altitude specification helps engineers plan ducting, cooling, and enclosure sizing, while the 40 °C ambient rating guides fan selection and service intervals. S1 continuous duty and single-speed operation fit standard automation processes. The motor’s 12 poles balance speed and starting torque for steady operation on conveyors and process lines, while cast iron bearings (6319/C3) and robust mounting options simplify installation and reduce maintenance cycles in challenging environments. Installation and compatibility advantages include standard frame 315 mounting and compatibility with ABB's M3BJ product family, enabling spare parts alignment, fast commissioning, and predictable maintenance cycles.
