Schneider Electric LC1D Contactor 4-Pole 40A 690V AC, 24V DC Coil, 1.56W Power LC1DT40BD

Schneider Electric LC1DT40BD Contactor is a high-performance 4-pole device designed with a 24V DC coil and a contact current of 40A at 690V AC. Part of the TeSys Deca Series, it is engineered for motor control and resistive load applications in demanding industrial environments.

This contactor offers robust mechanical durability rated for 30 million cycles, ensuring reliable and extended service life even in rapid or frequent switching scenarios typical of motor starters and large industrial lighting systems. The device’s breaking capacity of 450A at 440V limits damage from start-up overcurrent, improving plant availability.

The unit’s versatile mounting options include DIN rail installation, and it features screw terminals for secure and maintenance-friendly wiring connections. Its fast opening time between 16 to 24 milliseconds supports near-instantaneous switching, while the built-in bidirectional peak-limiting diode suppressor protects the coil from inrush currents.

Operational temperature ranges from -40°C to +60°C, making it suitable for harsh industrial settings such as shipyards, quarries, oil and gas plants, and pharmaceutical manufacturing. The contactor’s 4 normally open (NO) main contacts combined with 2 auxiliary contacts (one NO and one NC) increase its control versatility.

A protective cover shields internal components from airborne contaminants and reduces the risk of electric shock, enhancing safety during operation and maintenance. Compliance with international standards including CCC, CSA, EAC, IEC, RoHS, and UL confirms the product’s quality and regulatory adherence.

This Schneider Electric LC1DT40BD Contactor is manufactured in Indonesia and intended for industrial, manufacturing, HVAC, and electrical automation applications where reliable switching and control are essential.
