The instantaneous design (no intentional time delay on the RCD element) means it trips on the first half-cycle of a residual fault — no selectivity with downstream delayed RCDs, but full speed for personnel protection. ## Current derating and mounting Rated 10 A at 30 °C ambient; 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.","metaTitle":"Siemens 5SU9156-7KK10 SENTRON RCBO, 2-pole, 10 A, 10 mA, Typ","metaDescription":"Siemens 5SU9156-7KK10 SENTRON RCD-operated circuit breaker. 2-pole, 10 A, 10 mA Type A residual current, C-curve, 6 kA (EN 60898) / 10 kA (IEC 60947-2).
