Information About LUB12
The Schneider Electric LUB12 serves as the core power base of the TeSys U starter system, providing a modular platform for building customized motor starters rated up to 5.5 kW at 400V. Designed with a 3-pole configuration and a 12A thermal rating, it integrates essential switching elements, including power contacts, a control coil, and a rotary operating handle. Its modularity allows users to pair it with LUC control units to enable basic or advanced motor protection, monitoring, and control features. The LUB12 excels in demanding industrial environments, supporting high switching frequencies—up to 3600 cycles per hour—and offering long mechanical endurance of 15 million operations. Enhanced safety features, such as sectioning capability, fire-resistant components, and comprehensive electromagnetic immunity, ensure reliable and compliant operation across diverse motor-control applications.
Key Features:
- Modular TeSys U architecture: Allows users to build an “all-in-one” motor starter by combining the LUB12 with LUC control units, enabling scalable protection and control functions without redesigning the installation.
- High electrical and mechanical endurance: Rated for up to 15 million mechanical cycles and 3600 switching operations per hour, supporting continuous-duty industrial environments.
- Robust motor protection capability: Designed for 3-phase motors up to 5.5 kW at 400V, with a 12A thermal rating and Class 10 coordination when paired with the appropriate control unit.
- Integrated auxiliary contacts: Includes one NO and one NC contact for status signaling, interlocking, sequencing, or integration into control logic.
- Strong electrical resilience: Withstands 6 kV impulse voltage and meets IEC 60947-6-2 standards, ensuring secure performance during transient surges.
- Enhanced environmental resistance: Offers TH protective treatment, 960 °C fire-resistant supports, and full operation from –25 °C to +60 °C for use in harsh industrial settings.
- High reliability during disturbances: Immune to voltage microcuts and sags (3 ms and 70%/500 ms), ensuring stable operation in unstable electrical networks.
- Secure and flexible installation: DIN-rail or screw mounting, with a narrow 45 mm width that optimizes panel space while allowing easy integration into existing motor-control cabinets.
- Sectioning capability: Functions as an isolating component for safety and maintenance procedures, improving overall system operability.
- Wide certification compliance: Meets IEC, UL, CSA, CCC, EAC, and Marine requirements (with LUC), supporting global installation and multi-industry deployment.
The LUB12 delivers the reliability and precision required for modular, high-performance motor control systems across a broad range of industrial environments.
