The 16 A rated current with B-curve tripping characteristic means it protects lighting and general-purpose socket circuits against short-circuit and overload, while the 30 mA residual-current element provides earth-fault protection for personnel. ## Current derating and installation constraints At 40 °C it derates to 15.04 A, at 45 °C to 14.56 A, at 50 °C to 13.92 A, and at 55 °C to 12.96 A. If the distribution board runs warm — common in enclosed or multi-row panels — use the derated figure for the connected load.","metaTitle":"Siemens 5SU9306-0KK16 SENTRON RCBO, 16 A, 30 mA, Type B, 6 k","metaDescription":"Siemens SENTRON 5SU9306-0KK16 RCBO, 2-pole 1P+N, 16 A rated, 30 mA AC residual current, B-curve, 6 kA breaking capacity.
