10 A C-curve with 30 mA RCD in one module width
The Siemens 5SV9316-1CN10 is a combined RCBO from the SENTRON series — a single-pole-plus-neutral device that packs both overcurrent protection (C-curve, 10 A rated current) and residual current detection (30 mA, Type AC) into an 18 mm wide housing.
Supply can enter from either top or bottom, and the mounting position is unrestricted, which simplifies wiring in crowded panels where busbar routing is tight.
Residual current and overcurrent coordination
C-curve tripping (10× to 15× In) handles motor inrush and capacitive loads without nuisance trips, while the 6 kA Icn ensures the device clears a bolted fault before the upstream breaker needs to see it. Energy limitation class 3 means the let-through energy is low enough to protect downstream wiring and connected equipment during a short-circuit event.
