The Siemens 5SJ3110-7RC is a 1-pole miniature circuit breaker from the Retail line, rated 10 A with a C tripping characteristic and a 4.5 kA breaking capacity. The 4.5 kA breaking capacity at 230/400 V is sized for residential or light commercial distribution boards; it interrupts a fault up to that level without the arc re-striking, which is the core safety job of an MCB.
