The Schneider Electric LUB12 is a universal base unit of the TeSys U series, specifically designed as a power base for industrial motor starters. It combines the functions of a motor protection switch and a contactor in a compact module, enabling efficient and reliable motor control. With a rated current of 12 A and a rated power of 0.1 to 5.5 kW, it covers a wide range of applications, particularly for drives with low to medium power. The compact width of only 45 mm for powers up to 15 kW ensures space-saving installation, especially in control cabinets with limited space. A key advantage of the LUB12 is its modular design: the control voltage and exact current range are set only during final assembly via a plug-in control unit, offering high flexibility and adaptability to different requirements. The integrated protection and switching combination is standard-equipped with two auxiliary contacts (1 NC + 1 NO) and complies with IEC 947-6-2 requirements, including arc-free coordination. This makes the device suitable for use in demanding industrial environments where reliability and safety are paramount.
