FIELD: electricity.
SUBSTANCE: invention relates to an insulating device for connecting process input/output to field devices and comprises an insulator, in-built disconnecting element to enable disconnection of electrical connection between field device and insulating device, wherein the isolating device disconnecting element also provides a visual indication of the field device coupled to the disconnecting element, wherein said disconnector is a knife-type disconnector built into said insulator. Invention also relates to a connecting system for connection of field devices and to an insulating cabinet, containing plurality of said insulation devices.
EFFECT: technical result is providing reliable and clearly visible disconnection.
