The Siemens 5SV6316-7KP06 is a SENTRON AFDD-RCBO combination — an arc-fault detection device and residual-current circuit breaker in one compact unit. It protects a 230 V AC, 1P+N final circuit against series arcs down to 1 A and parallel arcs up to 500 A, while the 30 mA type A RCD catches residual currents. The 6 A C-curve MCB handles the overcurrent side.
The 6 A rated current with C-curve tripping means it's sized for lighting or small appliance circuits, not motor or high-inrush loads. The 30 mA residual-current sensitivity is the standard for personnel protection in residential and commercial final circuits. The IP20 rating applies only with the protective device and conductors connected — the terminals are live when the unit is removed from the rail.
