Tri Power X33 HE internal protections
The table below shows the sizes of the TRI POWER X33 HE isolators and the battery fuses (SWBATT) which are all
accessible from the front of the TRI POWER X33 HE. Moreover, the table shows the maximum input and the
nominal output currents.
Fuses must be replaced with ones of the same type and of the same rating, as shown in the table.

under a 7A charge.
Short circuit
If a fault occurs on the load, the TRI POWER X33 HE protects itself by limiting the value and the duration of the
current supplied (short circuit current). These values also depend on the TRI POWER X33 HE operating status at the
time of the fault, which can be either:
TRI POWER X33 HE in NORMAL OPERATION: the load is instantly commutated to the bypass line (TRI
POWER X33 HE 30kVA I2t=20000A2s; TRI POWER X33 HE 40kVA I2t=25000A2s): the input line is
connected to the output with no internal protection (locked after t>0.5s)
TRI POWER X33 HE in BATTERY OPERATION: the TRI POWER X33 HE protects itself by supplying an
output current which is about 1.5 the nominal current for 0.5s, after which it shuts down.
Backfeed
This TRI POWER X33 HE is also equipped with an internal protection against backfeed through metal separation
devices.
An optional output on the relay board is available for activating a release device to be installed Tri Power X33 HE
tream from the TRI POWER X33 HE.
This TRI POWER X33 HE has an internal device (redundant bypass power supply) which, in case a fault
occurs, activates the bypass automatically, thus maintaining the load powered with no internal protection
and with no limit on the power supplied to the load.
Under such emergency conditions, any disturbance on the input line will affect the load.
Please see the paragraph “Redundant auxiliary power supply for automatic bypass”, in the “USE” section.
