VALUE OF THE OUTPUT PROTECTIONS FOR SELECTIVITY**
Normal fuses (GI) In (Rated current)/5.5
Normal switches (Curve C) In (Rated current)/5.5
Extra Fast fuses In (Rated current)/2
* With single-phase input.
** Complying with these values, the UPS will be able to provide the power required to interrupt the output protection in
the case of a short-circuit without switching the load to the mains supply.
