Schneider Electric TeSys LC1 - D Contactors TeSys Contactors from Schneider Electric combine long mechanical and electrical life to offer a high reliable contactor. The range has been designed for integration in control systems and can be used to create motor starters for any type of application. The TeSys contactors offer quick simple setup while maintaining compliance with international standards. Features and Benefits • Typically, applications include resistive loads and motor control
• Highly reliable
• Excellent quality
• High resistance to shock and vibration
• Can be panel mounted with screws or DIN Rail mounted
• Easily installed accessories 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. What accessories are available? • Auxiliary contact blocks with serrated wiping action
• Front mount dust tight auxiliary contact blocks
• Pneumatic time delay blocks
• Transient voltage surge suppressors
• Interface modules and electronic timers
• Mechanical latching blocks Is the TeSys D range a double break pole type contactor? Yes, the TeSys D range uses linear translation movement that provides double breaking of the poles.
