Schneider Electric TeSys K LC1K Contactors. Schneider Electric TeSys K provide you with a choice of reversing and non-reversing contactors. TeSys K contactors, unlike relays, are specifically designed to connect to high current load devices. Used in larger-scale applications, Schneider Electric contactors can be controlled remotely, specifically designed to switch a large amount of electrical power through its contacts. The contractors feature varied switching voltages, many of the range feature screw clamp or a solder termination. TeSys K contactors offer you the best performance and compactness ratio plus also ensuring easy integration in all applications.

What does the utilisation category AC1 and AC3 mean for the TeSys contactors? Contactor utilisation categories define the current making and breaking values, based on the type of load to be controlled and the operating cycle conditions.

• AC-1: This applies to all AC devices with a power factor of at least 0.95. Example of use: resistive load, heating, distribution.


• AC-3: This applies to squirrel cage motors where breaking occurs while the motor is running. Example of use: all squirrel cage motors, lifts, escalators, conveyors, bucket elevators, compressors, pumps, mixers, air conditioning units.
