• Flexible control circuit to suit a wide range of applications
• High-fault short circuit current ratings provide the flexibility to select any component 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. Are the TeSys K contactors suitable for applications in AC4 usage? The LC1K series is suitable up to a maximum of 440 V ac in category AC4. Is the TeSys K range a double break pole type contactor? Yes the TeSys K range uses linear translation movement that provides double breaking of the poles.
