Schneider Electric TeSys D LC1D Contactor, 24 V ac Coil, 3-Pole, 38 A, 18.5 kW, 3NO, 440 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 LC1D38B7 model is a 3 pole contactor featuring a 24 V ac operating coil, with an AC-3 full load current rating of 38 A.

• Mechanical durability of 15 million cycles for long-lasting performance
• IP20 rating means it's finger-safe and protected against objects larger than 12mm
• Comes with a protective cover to prevent tampering
• Broad operating temperature range of -40°C to +60°C for use in demanding environments
• Light weight of 380g to put minimal strain on your equipment

• HVAC systems
• Conveyor belts
• Industrial pumps
• Automotive engineering

It has an opening time between 4 and 19ms and a closing time between 12 and 22ms, so it gives you the rapid-fire switching needed for speedy circuit control.
