33 NOTE A PV fuse-link operates under two main conditions:
34
35 • Short-circuit in a string (see IEC 62548 and IEC 60634-7-712 or in an array or sub-array (see IEC 62548 and IEC
36 60634-7-712) which leads to a very low over-current.
37
38 • Short-circuit current supplied by the discharge of the PV inverter through a very low inductance. This short-circuit
39 condition leads to a very high rate of rise of current equivalent to a low value of time constant, corresponding to
40 Table 104.
