Breaking capacity is 6 kA per EN 60898 for domestic/commercial distribution boards, and 10 kA per IEC 60947-2 for industrial panel applications — the higher figure gives you coordination headroom in a sub-distribution board with a 10 kA prospective fault level. ## Thermal derating and installation The 10 A rating holds at 30 °C ambient; above that, derate to 9.4 A at 40 °C, 9.1 A at 45 °C, 8.7 A at 50 °C, and 8.1 A at 55 °C. In a sealed, high-fill panel near other heat sources, use the 40 °C column for realistic continuous load planning. Halogen-free and silicon-free construction supports compliance with low-smoke, zero-halogen material requirements common in rail, marine, and public-building installations. The product is classified per IEC 81346-2 and DIN EN 61346-2 as function F (protection).","metaTitle":"Siemens 5SU9356-1KX10 SENTRON RCBO, 10A, 30mA, Type AC, 6kA","metaDescription":"Siemens 5SU9356-1KX10 SENTRON RCBO, 2-pole, 10A rated, 30mA residual, Type AC, 6kA (EN 60898) / 10kA (IEC 60947-2), Class C trip.
