It protects a single-phase final subcircuit against both overload/short-circuit (6 A, C-curve) and earth leakage (30 mA, Type A). Type A residual current detection covers pulsating DC fault currents from electronics (SMPS, dimmers, EV chargers) that a plain AC type would miss. At 18 mm wide (1MW) and 77 mm deep, it leaves room for cable bending space in a 125 mm tall enclosure. Mounting position is any — vertical, horizontal, or flat — so panel layout constraints are minimal. ## Thermal derating — the real-world current rating The 6 A nominal rating holds at 30 °C ambient. At 40 °C it derates to 5.64 A, at 45 °C to 5.46 A, at 50 °C to 5.22 A, and at 55 °C to 4.86 A. If the distribution board runs warm — say, inside a metal enclosure in a plant — the actual continuous load limit is lower than the label. Plan for the derated figure at your expected ambient; the 75 °C maximum is the storage/shipping limit, not an operating rating.","metaTitle":"Siemens 5SU9304-7KK06 SENTRON RCBO, 6A C-curve 30mA Type A,","metaDescription":"Siemens SENTRON 5SU9304-7KK06 RCBO, 1P+N, 6A C-curve, 30mA Type A residual current, 10kA breaking capacity.
