It carries a 10 kA short-circuit current rating (SCCR). The unit is instantaneous (no short-time delay), meaning it trips within milliseconds on a residual current — standard for general-purpose shock protection in distribution boards. Snaps onto DIN rail (REG mounting) and occupies 4 width units (72 mm wide) — standard 4-pole RCCB footprint for a 400 V three-phase + N panel. Depth is 70 mm, same as installation depth; height is 90 mm. Supply can land top or bottom; neutral is on the left (N left variant). ## Thermal performance and derating At 65 °C it drops to 57.35 A, and at 70 °C to 48.84 A.","metaTitle":"Siemens 5SV5346-6KL SENTRON RCCB, 4P, 63 A, 400 V, Type A","metaDescription":"Siemens 5SV5346-6KL SENTRON 4-pole RCCB, 63 A at 40-60 °C, 400 V AC, Type A, 10 kA SCCR.
