The 30 mA residual trip covers personnel protection (indirect contact) and fire prevention in standard AC circuits. ## Deployment context IP20 applies only when the board is closed and conductors are connected — not for open-panel or wet-area use. Rated for any mounting position, so orientation in a crowded enclosure is flexible. Rated 16 A at 30 °C ambient; at 40 °C the continuous current drops to 15.04 A, at 50 °C to 13.92 A, and at 55 °C to 12.96 A. If the distribution board runs warm — near other breakers or in a sealed enclosure — the 40 °C or 50 °C row is the one that governs the load you can actually protect. The unit survives -40 °C storage and 75 °C maximum, but the operating derating curve is what matters for continuous load. Listed as current-production (active lifecycle).","metaTitle":"Siemens 5SU9304-0KK16 SENTRON RCBO, B Curve 16 A 30 mA 10 kA","metaDescription":"Siemens SENTRON 5SU9304-0KK16 RCBO, B curve, 16 A rated, 30 mA residual trip, 10 kA breaking capacity.
