Schneider TeSys Giga LC1G contactors are high-power contactors for TeSys motor control applications, covering 115 A to 800 A AC-3. The series uses electronic wide-band coil control, compact modular construction and built-in diagnostic functions to simplify installation, maintenance and stock management.
The Schneider Electric TeSys Giga LC1G Contactor is a high-power contactor designed for motor control and power switching in demanding industrial electrical systems. Covering AC-3 rated operational currents from 115 A to 800 A and AC-1 thermal current ratings up to 1,050 A, the series offers 3-pole and 4-pole configurations for different load requirements. With advanced and standard control module options, integrated diagnostic functions and replaceable switching components, the TeSys Giga LC1G series provides flexible switching solutions for industrial motor control, power distribution and heavy-duty electrical applications.
The TeSys Giga LC1G series is designed for frequent switching operations in high-current electrical circuits. It supports multiple utilization categories, including AC-1 for non-inductive or slightly inductive loads, AC-3 and AC-3e for squirrel-cage motor starting and switching, and AC-4 for demanding motor operations such as inching and plugging. Additional utilization categories support lighting, transformer and capacitor switching applications, subject to the corresponding model ratings. Its robust contact system is designed to handle high making and breaking currents in industrial operating conditions.
The LC1G series offers two control module versions to accommodate different control system requirements:
Advanced Version: Supports wider AC/DC control voltage ranges and additional diagnostic capabilities. Its X1-X2-X3 PLC input terminals allow direct control through compatible high-density PLC solid-state outputs without an intermediate relay. It also supports an optional Remote Wear Diagnosis module.
Standard Version: Provides conventional contactor control through A1-A2 terminals, offering a practical solution for general industrial switching applications.
Both versions feature electronic control modules, built-in surge suppression and removable push-in control terminals. The control module can also be replaced separately when an internal malfunction is detected, simplifying maintenance.
Designed to support equipment maintenance and operational reliability, the TeSys Giga LC1G incorporates contact wear diagnosis and control voltage monitoring functions. The embedded contact wear algorithm estimates the remaining service life of the main contacts based on switching operations. When the remaining contact life falls below 15%, a front-panel diagnostic LED provides a local indication. Advanced versions can also transmit wear information through an optional Remote Wear Diagnosis module, helping maintenance teams plan component replacement before contact wear affects normal operation.
The advanced contactor design also allows switching module maintenance without disconnecting the main power circuit connections, reducing maintenance work during scheduled servicing.
The TeSys Giga LC1G series is available in 3-pole and 4-pole configurations for different electrical system arrangements. Its control voltage options support both AC and DC supplies, while compatible auxiliary contact modules provide additional switching status signals for control circuits. The series can be integrated with TeSys Giga electronic overload relays to form motor control assemblies with coordinated switching and overload protection.
A range of power connection accessories, auxiliary contact modules, terminal extensions and mounting components is available to accommodate different switchboard layouts and installation requirements.
The TeSys Giga LC1G high-power contactor is suitable for motor control and power switching in industrial electrical systems. Typical applications include:
Industrial Motor Control: Switching and control of high-power motors in manufacturing and processing facilities.
Pumping Systems: Contactor control for industrial water pumps, process pumps and large motor-driven pumping equipment.
Compressors and Fans: Switching operations for industrial air compressors, ventilation systems and high-power fans.
Material Handling: Motor switching for conveyors, lifting equipment and industrial material handling systems.
Power Switching: Control of electrical loads in industrial distribution panels and motor control centers.
Process Machinery: Switching operations in production lines and heavy-duty industrial equipment.
