» Mountings

Basically the L-series are designed for vertical wiring. Horizontal wiring is available for Panel Mounting and Base Mounting.

Panel Mounting

The Panel Mountings are well used mountings which cover wide application ranges.

  • Thefour hole mountings, which are fixed by 4 screws around the center shaft hole. The four hole mountings provide several variations which make them fit for all tasks.

Base Mounting

Base Mounting is used to fix a switch at the rear side, therefore it is the commonly used mounting for larger distributing cabinets.

The switch can be mounted at the base panel by four screws. For this mounting, several door clutches with or without padlock are available.
