The 80 A rating at 40 °C is the headline number, but the derating curve matters in a warm panel: at 45 °C it carries 77.57 A, at 50 °C it drops to 74.59 A, and at 60 °C it's down to 64.47 A. If your distribution board runs hot — say 55 °C ambient — the effective continuous current is 70.22 A, not 80 A. Depth is 70 mm, so it fits standard 100 mm deep enclosures without conflict. Finger and back-of-hand safe per the protection class. This is an instantaneous RCCB (no short-time delay), so it trips on any residual AC current above the threshold without intentional delay. That means in a multi-level distribution board, you need upstream selectivity — typically a time-delayed S-type RCCB or a selective main breaker — to avoid a full-panel blackout on a downstream fault. The permissible I²t value of 110 000 A²·s gives the let-through energy for coordination with upstream MCCBs or fuses. ## Deployment context Designed for DIN-rail mounting inside a distribution board or sub-distribution panel. The 4-pole format covers three-phase plus neutral, typical for 230/400 V TN-C-S or TN-S systems. Type AC means it detects sinusoidal residual currents only — not suitable for pulsating DC or smooth DC fault currents (those need type A or type B RCCBs).","metaTitle":"Siemens SENTRON 5SV4747-0 RCCB, 80A 4P AC, 10kA","metaDescription":"Siemens SENTRON 5SV4747-0 4-pole RCCB, 80 A rated, 230/400 V AC, 10 kA SCCR, instantaneous AC type.
