摘要

The decoupling unit has electrical components, which are provided in an integral part of a plastic overmoulding block (2), which is positioned on top of an insulating supporter (1), where the insulating support is connected to the plastic overmoulding block through a screw connection (4). A connector plug (10) is fastened to a cable (9), which is led out from the plastic overmoulding block, where the plug has a built-in switch (11), which is opened when the plug is plugged-in a measuring line (12) and closed when the plug is not plugged-in the measuring line.
