Schneider Electric TeSys D LC1D Contactor, 24 V dc Coil, 4-Pole, 20 A, 4NO, 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 LC1DT20BD model is a 4 pole contactor featuring a 24 V dc operating coil, with an AC-3 full load current rating of 20 A

• Integrated auxiliary contacts signal control devices when switching, for remote monitoring
• Protective cover guards the front plate against impacts to keep sensitive parts going strong
• Compact dimensions of 45 (W) x 85 (H) x 99mm (D) to pack tightly onto a busy rail
• Mechanical lifespan of 30 million operations, so it gives long-term switching performance

• HVAC systems
• Electrical generators
• Food production

This contactor completes up to 3600 switching cycles per hour, meaning it won't buckle under intense demand.
