The Type A fault-current design detects both sinusoidal AC and pulsating DC residual currents — the standard choice for circuits with single-phase rectifiers, switched-mode power supplies, or variable-speed drives downstream. The higher 10 kA figure gives the headroom needed for commercial or light-industrial distribution boards where fault currents exceed 6 kA. At 40 °C it derates to 59.22 A, at 45 °C to 57.33 A, at 50 °C to 54.81 A, and at 55 °C to 51.03 A. Mounting position is any orientation. Supply can enter from either top or bottom, which simplifies busbar routing in multi-row panels. IP20 rated with conductors connected and the distribution board installed.","metaTitle":"Siemens 5SU9356-7KK63 SENTRON RCD-MCB, 63A Type A, 6kA/10kA","metaDescription":"Siemens 5SU9356-7KK63 SENTRON 2-pole RCD-operated circuit breaker, 63A rated, Type A fault current, 6kA (EN 60898) / 10kA (IEC 60947-2) breaking capacity.
