Note 1:

If the available fault current of the installation is below 30kA, a lower kAIC-rated breaker can be used.

Note 2:

For breaker settings, refer to below table listing available overload currents.

Note 3:

If the available fault current of the installation is less than 1200A for the 10kVA and 15kVA UPS sizes, and below 2300A for the 20kVA and 30kVA UPS sizes, a breaker (of the same value as for the bypass input) can be used.

Note 4:

Recommended maximum rating of a single-fuse configuration if the internal bypass is to be protected during a load short-circuit.
