TeSys LUCA12BL Standard Control Unit (3-12A, 24VDC, Class 10)
The LUCA12BL TeSys Ultra Standard Control Unit is a core component for advanced motor control and protection within industrial and commercial applications, such as the Motor Control Center in car wash tunnels. This unit is designed to be paired with TeSys U power bases (e.g., LUB12, LUB32, LUB38, LUB120, LUB320, LUB380, and corresponding reversing contactor breakers) to form a complete and intelligent motor starter.
The LUCA12BL performs comprehensive protection and control functions for motors. Its primary features include robust protection against overload and short-circuit, ensuring the safety and longevity of motors and associated equipment. It also provides essential earth fault protection and safeguards against phase failure and phase imbalance, critical for maintaining stable motor operation in three-phase systems. The unit incorporates a manual reset function for quick recovery after a fault.
With a thermal protection adjustment range of 3 to 12 Amperes and a Class 10 thermal overload class, it offers precise and responsive motor protection for self-cooled 3-phase motors up to 9 kW at 690V AC. The control unit operates with a 24VDC control circuit voltage, ideal for modern low-voltage control systems, and features a self-cooling method. Its modular, plug & play structure simplifies installation and allows for quick and efficient maintenance.
A significant advantage of the LUCA12BL is its Modbus connection, which enables seamless data configuration and transmission, facilitating advanced motor management, logging, and monitoring functions. This provides direct access to detailed operational information for every motor starter in the installation. The unit is designed for front mounting, has an IP20 protection rating (IP40 for the front panel outside connection zone), and operates reliably in ambient air temperatures ranging from -13°F to 158°F (-25°C to 70°C). It is extensively certified by major international standards (CE, UL, CSA, CCC, EAC, ATEX, Marine, etc.), confirming its high quality and global suitability. As a Green Premium product, it also demonstrates Schneider Electric's commitment to environmental sustainability, being halogen and PVC-free.
