Choose between gG and aR fuses according to the table under Quick guide for
selecting between gG and aR fuses on page 100, or verify the operating time by
checking that the short-circuit current of the installation is at least the value
given in the fuse table. The short-circuit current can be calculated as follows:
where
I
k2-ph
= short-circuit current in symmetrical two-phase short-circuit (A)
U = network line-to-line voltage (V)
