• SCDS3D12 Rated current : It makes rated current either when the value with 30% declining inductance or the generation of heat
becomes 30% near value by the rising one above another of thedirect current.
• Other type Rated current : The rate current indicastes the current when the inductance decreases to 65%. Over of it's nominal
value or D.C.current when the temperature rising t =40ºC lower, whichever is lower.
