RST 20i3
The 3 pole connectors are available in
four versions: the standard version for
general power applications, a version
for low voltage up to 50 V with ground
conductor; another version for
switching applications up to 250 V, and
finally a green coding for applications
in multi-phase systems.
Both connectors are mechanically
coded. This means that only associated
pairs of male and female can be
connected with the correct polarity.
You therefore have the security of
a clear separation of different
applications without having to redo
any incorrect connections.
The color of the connectors indicates
the links that belong together.
