Depth is 70 mm, height 90 mm. Grid spacing is 60 mm — standard for European distribution boards. Supply can land top or bottom. The IP20 rating is conditional on the distribution board being installed with conductors connected — expected for a panel-mount device. ## Short-circuit and coordination Rated short-circuit current is 10 kA per IEC 61008-1, with a permissible series fuse short-circuit current of 100 A. The rated impulse withstand voltage (overvoltage category III) suits fixed-installation downstream of the main panel. ## Thermal and environmental limits Silicon-free construction, which matters for potting or conformal-coating compatibility in sensitive electronics environments.","metaTitle":"Siemens 5SV4346-0 SENTRON RCCB, 63A 30mA 4P Type AC, 400V","metaDescription":"Siemens 5SV4346-0 SENTRON RCCB, 4-pole, Type AC, 63 A rated current, 30 mA sensitivity, 400 V AC.
