Schneider TeSys F LC1F contactors are heavy-duty industrial contactors for motor starting and high-current power switching. The TeSys F family covers AC-3 motor-control ratings from 115 A to 1000 A and AC-1 switching ratings up to 2600 A, with multiple coil, pole and voltage configurations for demanding industrial applications.
The Schneider Electric TeSys F LC1F Contactor is a heavy-duty power contactor designed for high-current motor control and electrical switching applications. Featuring robust contact construction, flexible coil voltage options and multiple pole configurations, the series supports AC-1, AC-3 and AC-4 utilization categories for different industrial load requirements. With high electrical endurance, a replaceable drawer-mounted coil design and a comprehensive range of accessories, TeSys F contactors provide flexible switching solutions for industrial machinery, power distribution and large motor-driven equipment.
The TeSys F LC1F series is designed for switching and controlling three-phase motors and resistive electrical loads. It supports different utilization categories to accommodate various operating conditions:
AC-1: Switching of non-inductive or slightly inductive loads, including resistive heating equipment.
AC-3: Starting squirrel-cage motors and switching them off during normal operation.
AC-4: More demanding motor operations, including inching, plugging and frequent reversing.
The robust power contact system supports high-current switching operations, making the series suitable for industrial equipment requiring frequent motor starting and stopping.
The LC1F series offers multiple AC and DC coil voltage options to accommodate different control circuit designs. Its control coil can be selected according to the available control power supply, while compatible auxiliary contact blocks provide additional signals for electrical control and monitoring circuits. The drawer-mounted coil design allows coil replacement without replacing the complete contactor, helping simplify maintenance and reduce equipment downtime.
Designed for demanding industrial environments, TeSys F contactors feature a robust mechanical structure and high electrical endurance. Selected models support operating rates of up to 2,400 switching cycles per hour and ambient temperatures up to 55°C. The series also offers replaceable contact kits and a range of dedicated accessories, supporting maintenance and extending the service life of the contactor assembly.
The TeSys F LC1F series is available in multiple pole configurations, including 2-pole, 3-pole and 4-pole versions for selected models. Panel-mounted installation and screw or busbar connection arrangements support integration into industrial control panels and motor control centers. Compatible accessories include auxiliary contact blocks, mechanical interlocks, coil modules and replacement contact kits. The contactors can also be combined with compatible thermal or electronic overload relays to form motor starter assemblies.
