Electrical conductive element for e.g. bus bar, has display units displaying whether potential different from defined potential rests against element, where display units include optical display unit

摘要

The element has display units (22a-22c) for displaying, whether a potential different from a defined potential rests against the element. The display units include an optical display unit e.g. light source such as LED, and/or a mechanical display unit and/or an acoustic display unit. Operating devices (24) release the display with actuation of the display units, where the operating devices have a latch mechanism. A housing of a bus bar (10) comprises three chambers (12) running in a longitudinal direction.
