Screw and Ring Type Terminal
32 – 63 Ampere
The C-series switches represent the classic cam switch by Kraus & Naimer and are available with screw & ring type terminals

This series has either easily accessible terminal screws, or can be connected with ring type terminals. The terminals are accessible either horizontally or vertically.

The switches of the C-series offer a solution for most cam switch applications. Different contact designs, contact materials and terminals allow for their use as control switches, instrumentation switches and motor switches as well as in electronic circuitry and aggressive environments.

Mountings

Basically the C-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. 
They consist of two main groups.

The two/four hole mountings, which are fixed by (2/4) screws around the center shaft hole.
While with 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 distribution cabinets. 
The switch can be mounted at the base panel by two or four screws and also by 'Snap-On' for DIN rail mounting.. For this mounting, several door clutches with or without padlock are available.
