Here are some details about this contactor:

The LC1D40AM7C is a three-pole contactor, meaning it has three main power terminals.

It has a rated operational current of 40 amperes (A), which indicates the maximum continuous current it can handle.

The "M7C" in the model number denotes the coil voltage rating of the contactor. In this case, it indicates that the coil voltage is 230 volts alternate current (VAC) at 50 hertz (Hz).

The contactor is part of Schneider Electric's TeSys D range, which is designed for motor control applications.

It has built-in auxiliary contacts, commonly used for control and signaling purposes.

The LC1D40AM7C contactor is compatible with standard AC power supply systems.
