The Siemens 5SY4208-7CV is a 2-pole miniature circuit breaker with a C8 tripping characteristic and a rated ultimate breaking capacity (Icu) of 15 kA at 400 V AC. The C8 curve means it is designed for moderate inrush loads — typical for general-purpose distribution circuits feeding mixed resistive and small motor loads — where the instantaneous trip threshold is 8 to 12 times the rated current (64 to 96 A for this 8 A unit).
