Description

Schneider Electric LC1D38B7 TeSys D Contactor is an electrical device used to switch an electrical circuit on or off. It is similar to a relay, but it's designed to handle higher currents. It is a three-pole contactor. This means it can control three separate circuits. AC-3 is an electrical classification. AC-3 is for applications where the main power is AC and the load is primarily resistive or slightly inductive.

<= 440V 38A is the maximum voltage and current that the contactor is rated for. It can handle up to 440 volts and a current of up to 38 amperes. 24V AC 50/60Hz Coil specifies the coil voltage and frequency. The coil is the part of the contactor that generates the magnetic field to close or open the contacts. In this case, it operates on 24-volt AC and can handle frequencies of either 50Hz or 60Hz.

So, to summarize, Schneider Electric LC1D38B7 TeSys D Contactor is designed to handle up to 440 volts and 38 amperes in AC-3 applications. It's a three-pole contactor and operates on a 24V AC coil with a frequency range of 50/60Hz.
