Electrical parameters for selecting protective devices

The parameters given in the table opposite can be used to determine the required rating of the source side protective circuit breaker on Mains 1 of a single-unit or modular UPS, a frequency converter, or a parallel UPS with SSC.

Important:

It is essential to choose the type of circuit breaker according to its breaking capacity and the prospective short- circuit current at its place of installation.

Note:

For Mains 1 power supply voltages of 380, 400 and 415V, the Mains 1 current is the same because it is a function of the DC voltage.

The parameters given in the table opposite can be used to determine the required rating of the source side protective circuit breaker on the Mains 2 line for a single-unit or modular UPS.

Important:

It is essential to choose the type of circuit breaker according to its breaking capacity and the prospective short- circuit current at its place of installation. This choice must also be made so as to protect the static switch semiconductors and ensure discrimination with respect to the UPS output fuses (refer to "appendix" chapter).

For an installation with a Static Switch Cubicle, the Mains 2 currents indicated in the table must be multipled by the number of parallel-connected rectifier-inverter cubicles required to supply the load power (i.e. without taking redundant rectifier-inverter units into account).

Remark:

If the installation includes a transformer on the Mains 2 input, allow for the inrush current caused by magnetization of the transformer windings.

(1)the Mains 2 currents have been determined for a rated phase-to-phase voltage of 415V, 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 curent" column and check that the circuit breaker tripping curves are compatible with the data in the overload columns. For a Mains 2 voltage of 380V, multiply the currents indicated in this table by 1.09.

For a Mains 2 voltage of 400V, use the table in another language version of this manual.
