Cables & Connectors/Ceeform

CEEform - also known as C-form or CEE plugs, and more correctly as IEC 60309 - is a standard used to define plugs and sockets for power distribution.


There are a range of colours, sizes and pin configurations available - and importantly it is not possible to mate the wrong combination of plug and socket.

The colour of the plug and socket identifies the voltage which it is designed for - in our case, blue for 200–250V (i.e. Single Phase) and red for 380–480V (i.e. Three Phase).

The diameter identifies the current the connection is expected to carry. Most of the ceeform we work with is rated for 16A, though for distribution to the Rubber Boxes we also use connectors rated for 63A and 125A.
