The instantaneous design means no intentional delay on fault; it clears fast. The 20 A rating at 30 °C derates to 18.8 A at 40 °C, 18.2 A at 45 °C, 17.4 A at 50 °C, and 16.2 A at 55 °C — the thermal curve governs real-world continuous load, not the 30 °C label. The 30 mA residual trip covers AC fault currents (Type AC), standard for general-purpose socket circuits and lighting finals. Mounts on a DIN rail in any orientation — the housing is rated for any mounting position. Supply can enter from top or bottom. The IP20 rating applies once installed in a distribution board with conductors connected — it is not a standalone outdoor device. Pollution degree 2 (normal, non-conductive) and overvoltage category III (distribution level) are standard for fixed-installation panel gear.","metaTitle":"Siemens 5SU9306-1KK20 SENTRON RCBO, 20A, 30mA, Type C, 6kA","metaDescription":"Siemens 5SU9306-1KK20 SENTRON RCBO, 1P+N, 20A rated, 30mA residual, Type C curve, 6kA per EN 60898.
