The Siemens 5SJ6220-6RC is a 2-pole miniature circuit breaker from the Retail line, rated at 20 A with a B tripping characteristic and a 6 kA breaking capacity. The B-curve means it trips between 3 and 5 times rated current, suited for resistive or general-purpose loads where inrush is moderate — typical for lighting circuits or small distribution boards in commercial or light industrial panels.
