Protect Circuit protection

C120H circuit breakersB, C and D curvesEN 60898/EN 61009 : 15000 - IEC 60947-2 : 15 kA

FunctionProtection of cables against overloads and short-circuits in final distributionManual control and isolationEarth leakage protection when combined with a Vigi C120 module without

temperature derating: compliance with standard: EN 61009 (refer to pages 90265/2)Remote tripping, indication, by adding auxiliaries common to the entire C60/C120

range (refer to pages 90142/2).
