what are these components?

Hi

This is a picture of the progressive industries surge suppressor.

Does anyone know what these items are?

Sure - is this a trick question?

The box is obviously a hard wire EMS-HW50C, inside the plastic wrap to the right is the current sensor through which the wires run so the unit can read current draw, bottom left wrapped package is the remote monitor panel, to the right is the data cable that connects the box to the monitor panel, and at the bottom are screws to secure the box lid and wire connectors.

Anything else?

Remote display ? THAT'S my best guess.

Looks like two packages of bubblewrap, a telephone cable, and some wire terminals.
And a black box with some electronics inside.
