How do you connect a single phase load to a TeSys U?

In order to connect a single phase load to a TeSys U, you have to use a LUCC* protection module with an advanced base LUB**0. LUCM* multifunction control units were also capable of this, but are now obsolete.

In terms of wiring, the centre phase connections on the control unit are left unconnected, using live through pole 1 and neutral through pole 3.

Please see wiring diagram below:



This is not the same when using an electromechanical thermal e.g. LR** or electromechanical thermal magnetic e.g. GV**
