The Siemens 5SJ6463-7RC is a 4-pole miniature circuit breaker from the Retail line, rated 63 A with a C characteristic and 6 kA breaking capacity. The C characteristic means it trips between 5 and 10 times rated current — standard for inductive loads like motor circuits and lighting banks where inrush is moderate. The 6 kA breaking capacity at 400 V is sufficient for most sub-distribution boards; it safely interrupts a fault up to that level without cascading upstream.
