The Siemens 5SY5210-6CC12 is a 2-pole miniature circuit breaker from the 5SY5 series, rated for 440V DC with a 10kA breaking capacity and a B10 trip curve. The B10 characteristic means it trips between 3 and 5 times rated current — suited for resistive or slightly inductive loads where you need a bit of inrush headroom without waiting for a C curve.
