The 63 A rating holds flat from 40 °C through 60 °C, then derates to 57.35 A at 65 °C and 48.8 A at 70 °C — so in a warm enclosure you need to check the ambient temperature against the derating curve, not just the nameplate 63 A. The 30 mA trip threshold is standard for additional protection against direct contact (IEC 60364). The 10 kA short-circuit current rating (SCCR) means the device can safely interrupt a fault up to that level when backed by an appropriate upstream overcurrent device; the let-through current is limited to 7 100 A, and the I²t value is 110 000 A²·s — both figures for coordination studies. Installation depth matches the overall depth. Mounting position is any orientation.","metaTitle":"Siemens SENTRON 5SV4346-0KL RCCB, 4P, 63A, 30mA, Type AC","metaDescription":"Siemens SENTRON 5SV4346-0KL 4-pole RCCB, 63A rated, 30mA trip, Type AC, 10kA SCCR, 400V AC, 50 Hz.
