* Rating and rated current will be shown in a kind of a double designation and are separated by "RC" ("RC" = rated current). The rating refers only to the to the time/current characteristics, whereas the rated current indicates the maximum continuous current under standard test conditions and takes the maximum power consumption of standard fuse holders according to IEC 60269-2 into account. By using the RC-value, the derating for cyclic loads "A2" = 1 can be applied.
** Cyclic load factor "A2=1" can only be in combination with the given "RC" value
