LC1DT40U7

The Schneider Electric LC1DT40U7 is an electromechanical contactor belonging to the TeSys Deca range. This specific model is designed for non-reversing applications and features a 4-pole configuration with 4 normally open (NO) contacts. It is rated for a resistive load (AC-1) with an operational current of 40A at up to 440V AC and 60°C. The control circuit operates at 240V AC, 50/60Hz.

This contactor is built to handle demanding industrial environments, offering a rated operational voltage of up to 690V AC for the power circuit and 300V DC. It boasts a high making and breaking capacity of 450A at 440V. The device also includes a protective cover for added safety and has a mechanical durability of 15 million cycles and an electrical durability of 1.4 million cycles under AC-1 conditions.

Key electrical characteristics include a conventional free air thermal current of 40A for the power circuit and a rated insulation voltage of 600V for power circuits (CSA/UL) and 690V for signalling circuits (IEC). The rated impulse withstand voltage is 6kV according to IEC 60947. The coil technology does not include a built-in suppressor module, and control circuit voltage limits for drop-out are between 0.3 to 0.6 Uc, with operational limits between 0.8 to 1.1 Uc over a temperature range of -40°C to 70°C.
