The short-circuit current rating is 10 kA per IEC 61008-1 and EN 60898 (0.8 kA under those standards). This is the part to specify when the distribution board needs a 4-module-width (72 mm) RCCB for general-purpose AC circuits, not for pulsed DC or time-graded selectivity. The IP20 rating applies once the distribution board is installed with conductors connected; this is normal for enclosed panel gear, not for open washdown areas. ## Thermal derating — full rating up to 60 °C At 65 °C it derates to 57.35 A; at 70 °C to 48.8 A. For a panel running warm, the headroom to 60 °C means no derating in most industrial enclosures. The permissible I²t is 110 000 A²·s, and the let-through current is rated at 7 100 A — figures that matter for coordination with upstream MCCBs.","metaTitle":"Siemens SENTRON 5SV4746-0 RCCB, 4P, 63A, 500mA, 10kA","metaDescription":"Siemens SENTRON 5SV4746-0 4-pole RCCB, 63 A rated, 500 mA trip, 10 kA SCCR, Type AC instantaneous.
