The Siemens 5SL6150-6CC is a 1-pole miniature circuit breaker from the SENTRON 5SL6 family, rated 50 A with a B tripping characteristic and a 6 kA breaking capacity at 230/400 V AC. The 6 kA breaking capacity at 400 V tells you this breaker can safely interrupt a fault current up to 6,000 A without welding its contacts or failing to clear, which covers the majority of residential and light commercial panelboard applications where the prospective short-circuit current at the service entrance stays under that threshold.
