The Siemens 5SV9316-6NK32 is a compact RCBO combining overcurrent and residual current protection in a single 1P+N module. It carries a 6 kA rated short-circuit capacity (Icn) and a 30 mA Type A residual-current trip, with a B-characteristic curve and 32 A rated current (In) for 240 V AC single-phase circuits.
The Type A residual-current detection (30 mA) covers pulsating DC fault currents up to 6 mA smooth DC superimposed, which is the typical requirement for circuits with single-phase rectified loads (washing machines, LED drivers, EV chargers).
Panel integration
The compact 1P+N module occupies a single DIN-rail modular space (roughly 18 mm per pole), which simplifies panel layout when retrofitting RCBO protection into existing consumer units or distribution boards without expanding enclosure size.
