Its selective (time-delayed) design means it coordinates with downstream RCCBs: under a fault, the downstream device trips first, keeping the upstream supply live for the rest of the distribution board — critical for minimizing downtime on a multi-circuit panel serving a production line or warehouse aisle. Rated for 230/400 V AC at 50/60 Hz with a 10 kA short-circuit current rating (SCCR) per IEC 61008-1, it safely interrupts faults up to that level without cascading upstream — a key coordination figure for the site electrical engineer verifying panel SCCR. Depth is 70 mm; installation depth matches at 70 mm, so it sits flush with the rail edge — no overhang into the wiring channel. At 65 °C it derates to 57.35 A, and at 70 °C to 48.8 A. The storage range is wider: -40 °C to 75 °C. Operating ambient is -25 °C to 45 °C — fine for most indoor industrial panels, but if the enclosure sits in a hot machine cell above 45 °C, the derating curve applies.","metaTitle":"Siemens SENTRON 5SV3846-8 RCCB, 4P, 63A, 1000mA, Type A, Sel","metaDescription":"Siemens SENTRON 5SV3846-8 RCCB, 4-pole, 63 A rated, 1000 mA trip, Type A, selective, 10 kA SCCR.
