Mountings
Panel Mounting
The Panel Mountings are well used mountings which cover wide application ranges. 
They consist of two main groups.
• The two/four hole mountings, which are fixed by (2/4) screws around the center shaft hole.
• While at the single-hole mountings the shaft hole is used for fixation.
The two/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 two or four screws and also by 'Snap-On'. For this mounting, several door clutches with or without padlock are available.

In plastic enclosure
The Isolating Enclosures are classified into five groups:
• KS-, KL-, CS-, CL-Enclosures (IP66/67): With cover coupling with or without coverinterlock, strong durable plastic and increased wiring space.
• ST1-Enclosures (IP54): With abundant wiring space and entries with thread.
• PN-, PF-Enclosures (IP42, IP65): Small dimensions and entries with thread.
• PFA-PFF-Enclosures (IP54, IP65): For KG-switches only; entries with thread,with and w/o cover coupling and strongest durable plastic.
• PK-Enclosures (IP44): Enclosure with Lateral drive and entries with and w/o thread.
