Schneider Electric LC2D TeSys D Reversing Contactors TeSys D reversing Contactors from Schneider Electric combine long mechanical and electrical life to offer a high reliable contactor. The LC2D series is preassembled with reversing power busbar and has been designed for motor control or resistive load applications. The TeSys D contactors offer quick simple setup while maintaining compliance with international standards. Features and Benefits • Built-in auxiliary contacts for added switching capability
• Pre-installed interlock
• Screw connections: IP20 finger-safe terminals with both North American and International terminal markings
• Can be panel mounted with screws or DIN Rail mounted
• Easily installed accessories
• Flexible control circuit to suit a wide range of 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. What is a reversing contactor? A reversing contactor is an assembly of two of standard contactors, with a mechanical and electrical interlock connecting them. The interlocks allow only one contactor to be closed (giving power supply to the motor) at any time. 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.
