Non-withdrawable technique for low-voltage (LV) switchgear motor circuit, has mechanically traversable operating, test and isolating positions in switchgear section

摘要

A non-withdrawable technique for the functioning unit of a motor branch circuit in low-voltage (LV) switchgear or switching-station has the possible operating position (1), test position (2) isolation/separated position (3) and removed position (4) mechanically traversable within the switchgear-panel without the connections having to be released on the intake (feed) side and the outgoing section.
