MV POTENTIAL CONDITION
The winding is not connected to earth potential.
On request: Earthed end of the windin connected to the
outer conductor (neutral) of the cable.
(1) On request: other voltages compatible with primary winding
insulation level.
(2) On request: other voltages compatible with secondary
winding insulation level.
(3) Other percentage values on request.
TED MMX - 16, 25, 32, 50 kVA
LV OUTLET
Two-pole 6 metre-long H.07.RN.F cable , cross-section:

terminal for H.07.RN.F. cable with a maximum
cross-section of 2 x 25 mm².
LV PROTECTION
Without LV protection
On request:
The cut-out device ensures magnetic protection and
thermal protection by means a probe incorporated in
the winding (only for the 16 and 25 kVA)
Breaking capacity: 16 kVA : 85 kA - 25 kVA : 85 kA
Protection by means of one HRC fuse
LV POTENTIAL CONDITION
One end of the LV winding is connected to the earthing
terminal (blue lead).
On request: centre tap of the LV winding connected to
the earthing terminal.
EARTHING TERMINAL
By means of a M10 threaded rod, connected internally to
the transformer core.
