Schneider Electric TeSyS D Contactor 24V DC Coil 3-Pole 9A 4kW 3 NO 690V AC LC1D093BD

Schneider Electric LC1D093BD TeSyS D Contactor is a compact, three-pole switching device designed for efficient motor control and resistive load applications in industrial and commercial electrical panels. It features a 24V DC coil equipped with a built-in diode that helps reduce coil transient effects, enhancing operational reliability.

This contactor supports a contact current of 9A and a power rating of 4kW, making it ideal for switching three-phase motors in factory control panels, conveyor systems, pump systems, and machine tools. The device operates up to 60°C ambient temperature and accepts both plate and standard rail mounting for ease of panel integration.

The contactor offers an insulation rating suitable for contact voltages up to 690V AC and includes 3 normally open (NO) main contacts for straightforward control. Its spring terminals allow quick wiring and connection release, contributing to reduced installation time.

It also contains auxiliary signalling contacts mechanically linked as 1 NO and 1 NC, capable of handling up to 140A AC making capacity at 17V minimum switching voltage for control signalling circuits with high reliability.

Electrical endurance is robust, rated at approximately 2 million mechanical cycles for AC-3 duty at 9A and 440V, suitable for repetitive motor start-stop cycles. The device is designed for harsh industrial environments with a temperature operating range from -5°C to 60°C and can be used at altitudes up to 3,000 meters with appropriate derating.

Applications include motor control and resistive load switching in automation panels for manufacturing, HVAC systems, water treatment facilities, and other industrial processes requiring compact, reliable contactors.
