Installation switching device i.e. line safety switching machine, for arrangement on support rail, has oblong hole-like port or short connecting line whose longitudinal axis runs transverse to longitudinal direction of support rail

摘要

The device (1) has a housing (2) in which a bus bar and a conductor connection unit e.g. screwless clamping terminal, are arranged. Two external conductors are electrically connected with the bus bar over the conductor connection unit. The housing for the external conductors comprises an oblong hole-like port or two separate ports (2.1) arranged next to each other. Longitudinal axis of the oblong hole-like port or a short connecting line (12) runs transverse to a longitudinal direction of a support rail.
