class=311411616-20022019>Dnes jsou proudové chrániče s integrovanou jistící
spouští při nadproudu a ten je potom dán hodnotou chrániče např. 16A, 20A, 25A
(nejvíce používané 3f nebo 1f). Tudíž k nim nemusíte předřadit žádný jistič
protože tuhle funkci umí. Pak je pouze proudový chránič bez integrované funkce
jističe a tam předřadný jistič musíte použít. Tyto chrániče mají udanou hodnotu
proudu např 25A, 40A pouze jako spínací, vypínací schopnost kontaktů chrániče a
vůbec tato hodnota nesouvisí s hodnotou předřadného jističe pokud jeho hodnota
není vyšší než hodnota uvedená na chrániči. </SPAN></FONT></DIV><BR>
