The C-curve characteristic means it trips between 5 and 10 times rated current — suited for moderate inrush loads like small motors or transformer banks in distribution panels. The 15 kA Icu (ultimate short-circuit breaking capacity) at 400 V tells you this breaker can safely interrupt faults up to that level without upstream damage — a key spec for panel SCCR coordination in industrial or commercial mains distribution.","metaTitle":"Siemens 5SY4405-7CV MCB, 15kA 400V 4P C0.5","metaDescription":"Siemens 5SY4405-7CV MCB, Icu=15kA at 400V, 4-pole, C0.5 curve.
