Description
Schneider Electric LC1D12BD TeSys D Contactor is an electrical device used to switch an electrical circuit on and off. It's typically used for controlling electric motors and other high-power loads. 3P stands for three-pole, which means it can control three separate circuits. AC-3 refers to the utilization category for contractors. AC-3 contactors are designed for normal, uninterrupted operation. They are used for starting squirrel-cage motors.
<= 440V 12A is the maximum voltage and current the contactor is rated for. It can handle voltages up to 440 volts and currents up to 12 amperes. 24V DC Coil is the voltage required to energize the coil of the contactor. In this case, it requires a direct current (DC) voltage of 24 volts to activate.
In summary, Schneider Electric LC1D12BD TeSys D Contactor is designed for three-phase applications, can handle up to 440 volts and currents of up to 12 amperes, and requires a 24-volt DC signal to operate. It's commonly used for starting and stopping motors in industrial settings
