Design and Performance
Modular Foundation for the TeSys U Starter System
As a power base within the TeSys U modular motor control system, the LUB12 accepts interchangeable control units (LUCA, LUCB, LUCC, LUCD, LUCM), allowing motor protection parameters and control voltage to be configured or changed without rewiring the power circuit.
High Mechanical Durability for Frequent Switching
Rated for 15,000,000 mechanical cycles at up to 60 cycles per minute, the LUB12 supports demanding applications with frequent start-stop operation, reducing the need for premature replacement.
Flexible Control Voltage Compatibility
Supporting control voltages from 24 V up to 240 V AC or 220 V DC depending on the control unit installed, the LUB12 offers broad flexibility to match existing control circuit standards across different installations.
Strong Short-Circuit Breaking Performance
Rated service breaking capacities of up to 50 kA at 230/440 V provide robust fault interruption capability, supporting reliable protection in demanding low-voltage industrial power distribution systems.
Quick Maintenance and Detailed Diagnostics
The modular, plug-and-play structure enables quick maintenance, while providing direct access to detailed information for every motor starter in the installation, supporting an advanced motor management approach.
