Bypass AC source
The parameters given in the table
opposite can be used to determine the
required rating of the upstream
protective circuit breaker on bypass AC
input.
Important:
It is essential to choose the type of
circuit breaker for bypass AC input
according to its breaking capacity and
the prospective short-circuit current at
its place of installation (see Schneider
Electric LV documentation).
This choice must also be made so as to
protect the static-switch
semiconductors with respect to the
maximum permissible currents (see
table opposite) and ensure
discrimination between the UPS output
fuses (see the fuse curves in figures 1
and 2) and the downstream protection
devices.
Remark:
If the installation includes a transformer
on the bypass AC input, allow for the
inrush current caused by magnetisation
of the transformer windings.

(1) the bypass AC source currents have been
determined for a rated phase-to-phase voltage of
400 V, a load power factor of 0.8 and for full rated
load as well as overloads of 25% or 50%. When
choosing the circuit breaker rating, use the "rated
current" column and check that the circuit breaker
tripping curves are compatible with the data in the
overload columns.
For a bypass AC source voltage of 380 V, multiply
the currents indicated in this table by 1.09.
For a bypass AC source voltage of 400 V, multiply
the currents indicated in this table by 1.04.
