Schneider LC1DT80 4-pole contactors

Schneider LC1DT80 belongs to the TeSys D series of 4-pole contactors, primarily rated for 80A resistive loads and suitable for circuit control requirements in various industrial scenarios. Models with different suffixes vary in details such as coil voltage. Below is a detailed introduction to its core information:

 1. Core Electrical Parameters

Basic Load and Voltage: Rated current of 80A, compatible with a maximum voltage of up to 690V AC, and also supporting power supply circuits of ≤300V DC. It falls under usage category AC-1, commonly used for switching on and off normally starting squirrel-cage motors and other equipment.

Coil Specifications: Coil voltages differ across models with different suffixes. For example, LC1DT80AND is 60VDC, LC1DT80AG7 is 120VAC, and LC1DT80AKUE is 100-250VAC/DC. Some models are equipped with a built-in bidirectional peak-limiting diode suppressor to enhance circuit stability.

Auxiliary Contacts: Standard configuration includes 1 normally open (NO) and 1 normally closed (NC) auxiliary contact. The auxiliary contacts are mechanically interlocked, and the NC contacts hold mirror certification, complying with relevant IEC 60947 standards to meet the signal feedback and control needs of auxiliary control circuits.

 2. Structural and Installation Features

Wiring Method: The control circuit uses screw-clamp terminals, compatible with 1-4mm² hard and soft cables; the power circuit adopts Everlink BTR screw connectors, capable of accepting 1-35mm² cables. The wiring is secure and adaptable to various cable specifications.

Mounting Methods: Supports two installation methods—DIN rail mounting and direct panel mounting—meeting different installation layout requirements in industrial settings. Some models have dimensions of 70mm×122mm×120mm (width × height × depth), featuring a compact design that saves installation space.

 3. Reliability and Certifications

Environmental Adaptability: Operating temperature range of -40°C ~ 70°C, with excellent vibration resistance (4g when closed, 2g when open), enabling it to handle complex industrial working conditions. It has an IP20 protection rating, effectively preventing foreign object intrusion.

Multiple Certifications: Certified by numerous international and domestic authorities including UL, CSA, IEC, CCC, and EAC. It also complies with RoHS/REACH environmental standards, making it an environmentally friendly product that meets industrial compliance requirements in different regions worldwide.

 4. Typical Applications

With its 4-pole, 80A load capacity, this contactor is widely used in scenarios such as industrial motor control, Heating, Ventilation, and Air Conditioning (HVAC) systems, and power distribution circuits. It can serve as a core component of motor starters to achieve reliable switching control of circuits for high-power equipment, and is also suitable for circuit control of resistive loads.
