The C curve means it handles moderate inrush currents typical of motor and lighting loads, tripping between 5 and 10 times rated current for short-circuit faults. The 15 kA Icu tells you this breaker can safely interrupt fault currents up to that level without welding its contacts or damaging downstream equipment — a critical spec for panel coordination in high-fault installations. The single-pole form factor snaps onto a standard DIN rail inside the enclosure. In a panel with multiple 5SY breakers, the 1-module width (roughly 18 mm per pole) keeps fill factor tight — plan for the same pitch as other Siemens 5SY units.","metaTitle":"Siemens 5SY4163-7CV MCB, 1P C63, 15kA Icu at 230/400V","metaDescription":"Siemens 5SY4163-7CV miniature circuit breaker, 1-pole C63 curve, 15kA breaking capacity at 230/400V.
