SCHNEIDER TeSys D Green series AC/DC universal contactor

Rich modular accessory system

The modular design of TeSys D Green is an extension of its powerful features, and users can flexibly expand its functions by adding side or top mounted accessories:

Auxiliary contact module:

Instantaneous auxiliary contacts (LAD N series): Provides additional NO/NC contacts for status feedback, interlocking, or indication.

Delay auxiliary contact (LAD T/R/S series): Provides power on delay or power-off delay function, with a delay range from 0.1 seconds to 180 seconds, and can be used for timing control such as star delta start.

Mechanical and Electrical Interlocking Module (LAD 6K10+): Used for assembling reversible contactors (forward and reverse control), providing mechanical interlocking to prevent simultaneous power on and off, ensuring safety.

Electronic functional module:

Solid State Relay Interface Module (LA4DWB): Provides isolated solid-state output interfaces.

Timer module (LA4DTU): Integrated delay function.

These modules are installed on LC1D40A~D80A contactors through LA4BB3 wiring adapters.

Connect and protect attachments:

Comb shaped busbar (GV2-G, GV3-G series): used for parallel power supply between multiple contactors or circuit breakers, simplifying cabinet wiring.

EverLink terminal module: convenient for wiring.

Protective Cover (LA9DET): Increases the level of safety protection.

Identification kit: facilitates device identification and management.

Integrated motor starter solution

The TeSys D Green contactor is the core component for building compact and efficient motor starters. Schneider Electric provides mature pre configured solutions:

Direct Starter (DOL):

Cooperate with GV2/GV3 motor circuit breakers to form an integrated starter with short-circuit and overload protection. The document provides a detailed selection comparison table (pages 19-21), clearly listing the circuit breaker models (GV2ME, GV3P, GV3L, NSX molded case circuit breakers) and contactor models (LC1D, LC1F) corresponding to motors ranging from 0.06kW to 250kW, and ensuring compliance with the "Type 1 coordination" requirements of IEC 60947-4-1 standard to ensure the safety of the system under short-circuit faults.

In conjunction with the TeSys GV adapter board system, the LAD311 adapter board allows for quick and neat installation of "circuit breaker+contactor" or "fuse+contactor" modules on DIN rails.

Reversible starter and star delta starter:

By using tool kits such as LAD9R1 and LAD9R3, two standard contactors can be easily assembled into reversible contactors with mechanical interlocks (LC2 series).

Provide dedicated star delta starter assembly kit (LAD9SD3, etc.), including delay contact module and all necessary connection bars.

Prefabricated Wiring System (TeSys SoLink):

This is an innovative solution for the future. By connecting the LADC module, the control and monitoring circuits of circuit breakers, contactors, and auxiliary contacts are integrated into the standard RJ45 interface. They are quickly connected to the PLC's I/O module through prefabricated cables, greatly reducing the workload of control circuit wiring in the cabinet and improving reliability and maintainability.

Core technical parameters and design points

Electrical and mechanical lifespan:

The mechanical lifespan can reach millions of operations.

The electrical lifespan (AC-3) can reach millions of times under rated conditions, and specific data needs to refer to the official data sheet.

Coil characteristics:

The suction time is about 50-60ms, and the breaking time is about 25ms, with precise movements.

Capable of operating within a wide voltage range and reliably releasing at voltages as low as 0.1Uc.

Installation and wiring:

Supports 35mm standard DIN rail (such as AM1DP200) installation, as well as panel screw installation.

Provide detailed recommendations for wire cross-sectional area (screw terminals support 1-35mm ², EverLink terminals support 1-25/35mm ²), and specify the correct tightening torque.

Environmental adaptability:

Working temperature range: -5 ° C to+60 ° C.

Storage temperature range: -60 ° C to+80 ° C.

The highest working altitude is 3000 meters without capacity reduction.

Protection level: Front IP20, preventing direct contact of fingers with live parts.

Application Value and Summary

The Schneider Electric TeSys D Green AC/DC universal contactor series is not just a component upgrade, it represents the trend of industrial control towards higher energy efficiency, higher integration, and more intelligent convenience. Its value is reflected in:

Reduce costs and increase efficiency for enterprises: Low energy coils save electricity costs, direct PLC drive saves components and cabinet space, modular design reduces inventory types.

Improving system reliability: Constant operating characteristics, excellent anti vibration design, extensive international certifications (UL, CSA, CCC, etc.), and a perfect "coordination" solution with upstream circuit breakers ensure long-term stable operation of the system.

Accelerate engineering and maintenance: Clear selection table, rich pre configured solutions, and SoLink prefabricated wiring significantly shorten design, installation, and maintenance time.
