Rapid fixing device for electrical installation device e.g. fault current circuit breaker, has slider with 3 arms with normal protrusions, with only center protrusion holding onto bearer rail

摘要

The fixing arrangement has an aperture with a fixed protrusion on one wall facing a protrusion on a sprung slider (10) on the other wall. The protrusions hold the installation device on the bearer rail. The slider has two parallel outer arms with normal outer protrusions and an intermediate arm with a normal protrusion (23). The distance from the intermediate protrusion surface (24) to the plane spanned by the outer arms has a smaller distance to the base of the installation device than the outer protrusion surfaces (20,21) so that only the intermediate protrusion holds onto the bearer rail in the mounted state.
