CONDITIONS of USE:
Environmental class AD7 : can be partly or completely
immersed in water for a limited time period.
MV INLET
A -Two -pole plug-in concentric, universal terminals for
3.6/6 kV concentric two -pole cable 2 x 6, 10, 16, or
25 mm² cross-section conforming to NF C33-221 standards.
B - «Lead-through» connection in transformer.
TAP CHANGER FOR VOLTAGE ADJUSTMENT
No adjustment.
MV PROTECTION
By means of HRC fuse, rupturing capacity 15 kVA.
MV POTENTIAL CONDITION
The winding is not connected to earth potential.
On request: Earthed end of the winding connected to
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.
TED MMX - 0.4 to 10 kVA
LV OUTLET
Two-pole 6 metre-long H.07.RN.F cable
< to 1 kVA : cross-section 2 x 2.5 mm²
1 to 5 kVA : cross-section 2 x 6 mm²
10 kVA : cross-section 2 x 10 mm²
On request : two-pole plug-in terminal for H.07.RN.F.
cable with maximum 2 x 25 mm² cross-section.
LV PROTECTION
Without LV protection
On request:
The cut-out device ensures direct magnetic protection
and thermal protection by means of a probe incorporated
in the windings; breaking capacity: 6 kA.
*Single-pole + neutral, curve B, for the TED ≤ 6 kVA
*Two-pole, curve B, for the TED > 6 kVA
By HRC fuses.
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. In this case, possible LV protection must
be two-pole.
EARTHING TERMINAL
By means of a M10 threaded rod, connected internally to
magnetic circuit.
