Line terminal box
The terminal block for generators frame size 250÷355 is normally provided with 6x terminals; the
terminal block for generators frame size 400÷560 is provided with 3 terminals only (one each phase),
to which the supply cables are connected.
In such case the connection of the windings is made inside the machine itself and it is not accessible.
On request, also generators frame size 400÷560 can be made with 6 terminals in order to have all
winding terminals accessible.
The terminal block is made in anti-mould non-hygroscopic material.
As mentioned, the terminal box (in aluminum alloy for the generators frame size 250÷355 and in steel
plate for bigger frame sizes) has IP 55 or IP 56 protection degree, provided that the connection of the
supply cables is properly made.
