Coding of the plugs and sockets
5.4 CEAG SICHERHEITSTECHNIK GMBH
The key to safety
Plugs and sockets with a cleverness:
The innovative coding of apparatus allows
plugs used for Zone 1 to be used in
sockets for Zone 2 and/or for usage with
industrial sockets as well. Hence, plugs and
sockets for Zone 1 can be used anywhere.
However, by the same token, the coding
ensures that Zone 2 plugs cannot be
operated in sockets with Zone 1 coding.
That guarantees safety with an enormous
flexibility in their usage.
Speaking of flexibility: It goes without saying
that the plugs of the existing range also
fit into the new sockets.
