Schneider Electric TeSys D LC1D Contactor, 24 V ac Coil, 3-Pole, 40 A, 18.5 kW, 3NO, 690 V ac

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 LC1D40AB7 model is a 3 pole contactor featuring a 24 V ac operating coil, with an AC-3 full load current rating of 40 A

• Broad operating temperature range between -40°C and +60°C for use in harsh industrial conditions
• Mechanical durability of six million cycles for long-lasting use
• IP20 rating means it's touch-proof and protected against tools and wires over 12mm
• Opening time of 4 to 19ms and closing time of 12 to 26ms for a rapid response

• Industrial power supplies
• Automated control and processing
• Agricultural equipment

Compact dimensions of 122 (L) x 55 (W) x 120mm (D) mean it's suitable for use in setups where space is tight.
