Electrical unit with a connector for a loop through conductor

摘要

The invention relates to an electrical unit comprising a mounting device for fastening the unit to a supporting element, e.g. to a mounting rail, and at least one insulation piercing connecting device provided with an insulation piercing element and with a holding element. The insulation piercing element and holding element can move in relation to one another. When the unit is fastened to the supporting element, a conductor can be inserted into the holding element. This enables aid conductor to be looped through the holding element. The conductor can be clamped by transferring the insulation piercing element and holding element into a closed position.
