TeSys D 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 D contactors offer quick simple setup while maintaining compliance with international standards.

• Built-in auxiliary contacts for added switching capability
• Screw connections: IP20 finger-safe terminals with both North American and International terminal markings
• Can be panel mounted with screws or DIN Rail mounted
• Bidirectional peak limiting diode suppressor to protect the coil
• Easily installed accessories
• Flexible control circuit to suit a wide range of applications

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.

• 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

Yes the Tesys D range uses linear translation movement that provides double breaking of the poles.

The Schneider Electric LC1DT20B7 model is a 4 pole contactor featuring a 24 V ac operating coil, with an AC-3 full load current rating of 20 A.
