The selective (S-type) design means it introduces a deliberate time delay so that downstream RCCBs trip first during a ground fault, keeping this unit closed to maintain power to upstream or critical circuits — essential for graded coordination in a distribution board where you can't afford a blind trip taking out a whole MCC. Rated short-circuit withstand is 10 kA per IEC 61008-1, with a permissible series fuse short-circuit current up to 100 A. ## DIN-rail fit and panel integration Depth is 70 mm, height 90 mm, grid spacing 60 mm. Installation depth 70 mm means it clears a standard 80 mm deep enclosure back wall with room for wiring. The silicon-free construction matters if you're potting or conformal-coating the panel later. Supply connection can enter from top or bottom; supplementary devices can be installed on the product extension. Overvoltage category III — suitable for fixed installation downstream of the service entrance.","metaTitle":"Siemens 5SV3647-8 SENTRON RCCB, 80 A, 300 mA, 4-pole, select","metaDescription":"Siemens 5SV3647-8 SENTRON selective RCCB, 80 A, 300 mA, 4-pole, 10 kA SCCR, 230/400 V AC.
