This is an MK RCD unit with LN6730s RCD inside. There are also 3x 32A blue plugs included.

The housing has sustained damage which has caused the screws and screw housing areas that hold the front panel on to snap off.

As this is the case, without repair, the unit is not electrically safe, therefore is sold As Is, as a damaged unit, for Spares/Repair/Restoration.
