Description
Schneider Electric LC1D18BD TeSys D Contactor is an electrical relay that is used to control a high-current circuit with a low-current signal. It's commonly used in applications like motor control. The contactor is a three-pole device. This means it can control three separate conductors (phases) simultaneously. AC-3 is the type of duty the contractor is designed for. AC-3 duty is specifically for applications where the contactor is used to start and stop squirrel cage motors during normal running conditions.
<= 440V 18A is the maximum voltage and current that this contactor can handle. It's rated for voltages up to 440V and a maximum current of 18A. 24V DC Coil is the voltage required to activate the coil of the contactor. In this case, it requires a 24V direct current (DC) supply to energize the coil and close the contacts.
In summary, Schneider Electric LC1D18BD TeSys D Contactor is a three-pole contactor designed for AC-3 duty. It can handle voltages up to 440V and currents of up to 18A.Â
