The Siemens 5SJ6208-7FC is a 2-pole miniature circuit breaker (MCB) rated at 8 A with a C-trip curve and a 6 kA breaking capacity. It is a current-production part per the manufacturer's lifecycle stage.
The 6 kA breaking capacity (Icn) means this MCB can safely interrupt a fault current up to 6,000 A at its rated voltage — sufficient for most residential and light commercial distribution boards where the prospective short-circuit current stays below that threshold.
Deployment context
The 2-module width (36 mm at 18 mm per pole) fits standard distribution board cutouts.
