SCHNEIDER ELECTRIC LU2B12B - Power Base for Motor Starter-Controller
The SCHNEIDER ELECTRIC LU2B12B is a TeSys U modular power base engineered for direct-on-line starting and protection of 3-phase asynchronous motors. It integrates the functions of a contactor and a thermal-magnetic overload relay, forming the core power switching component of a TeSys U motor starter-controller system. This unit is designed for industrial applications requiring robust motor control, such as pumps, fans, conveyors, and general machinery, providing reliable power switching and short-circuit protection.
